Being pedantic again, sorry: strictly speaking, `cd` is a shell command, not a system command, which is why it doesn't have it's own manpage. You can actually find it with `man bash`. But don't do that. Use Bash's `help cd` command, instead. Oh, and also you can `help help`. (Also as a scripter, I went ahead and downloaded the Bash documentation to my local hard drive so that I can study it in a browser.)
As Joe explains, when you use the 'touch' command without any options it will set the time of the file you give as an argument to the current time. But it's good to note that you can use 'touch' to set the time of a file to anything you want with the -d option. This option will even understand a bit of natural language, for example "touch -d yesterday file" will set the time of "file" 24 hours in the past.
Just subscribed. Finally someone who can explain Linux without putting me to sleep or pissing me off with goofy nerd trying to be cool humor or lack of.
As much as I hate coding and boring letter stuff-- guess it's time I learned some of the basic commands at least.. and I wanted to learn from you-- YOU make more sense teaching things...and there's no wasted fluff!!!
The clear command only clears commands from the screen. But if you use history -c, the c option means clear. this will clear everything you typed when you opened the terminal. But if you never use this command before and you think all the commands you have typed are gone by using the clear command then you are wrong. There is this file that keeps all the commands that you have used. This file is called .bash_histor. But that's when you exit the terminal. All the commands will save.
I know this is being picky, but sda1, sda2, sdb1, sdb2, etc are PARTITIONS, not drives. sda1 is partition 1 on physical drive sda, and sdb2 is a partition on physdical drive sdb. I think it's important to use the correct terminology, especially for the audience you're trying to reach. I enjoy your videos, though. Keep up the great work !! :-)
I am a beginner in learning Linux and other computer stuff. At first, I thought "why somebody is taking 34 minutes to tell about just 10 commands of Linux?" But it is really informative. Each minute of video is worth concentrating.
Instead of doing: cat file.txt | less you can do: less file.txt Thanks for the which tip, been using linux cli for over ten years and I didn't know this.
Great video. I just want to add a thing: 'cat' (abbreviation of concatenate) is actually used to concatenate (merge) two or more files. For example: cat file1.txt file2.txt file3.txt file_n.txt We can also redirect the output to, for instance, a file, like this: cat file1.txt file2.txt file3.txt > file_1_2_3.txt file_1_2_3.txt will consist of the contents of file1.txt, file2.txt and file3.txt Again, great video. Keep em coming.
Great "Linux Level 2" video - once we've gotten past cd, mv, ls, rm, and so on, we now have some cool commands that make life easier for us. In particular, I didn't know you could use shutdown -h as a kind of reverse alarm clock. Also, I find blkid useful for detecting USB drives. Thanks!
My 3 most useful at the moment: 1) sudo sysctl -w vm.drop_caches=3 Reclaims free memory, avoid hang ups 2) chmod +x /path/path/filename Makes a file executable (only local disk) 3) sudo apt clean Clean apt cache
It's late to tell you, but man is only for 'transient' commands. cd is an internal command inside bash (the shell). Help for internal commands of the shell is availlable with -> help so for your 'cd' command you would type -> help cd, and voila: there is the description of the command cd including all options ;) Additional info: cd without any 'arguments' puts you in your home directory, so it's not needed to type cd ~. cd on it's own is enough for going home ;)
You can also search inside of less with "/". "-i" will toggle case sensitivity (though if your pattern has caps it will still assume case sensitivity. "n" for next, "b" for back. Very useful for large text files.
Top 2 commands I suggest first to learn. #1 ' man intro ' #2 ' vimtutor '. If you use those to commands, and read everything contained in those commands, then you wont need to ask for help... for a long while.
Man, Puppy Linux is weird. One thing it does is opens a browser when you use the "man" command. I'm always root, unless I choose to be "Spot" (it says somewhere why, but I'll have to read up on that again). This is all so cool, though. Two months into playing around with Linux! I'm only mad at myself for not playing with it years ago.
10:15 to 10:26.. if it's native windows program or game..here's one way you can do that. right click on your mint desktop..select " Create a launcher" in the command field type the following info below at the beginning. wine start /unix note the one spacebar press between /unix and the exact path of the .exe file ans ensure one space bar press between wine and start .so an example could be wine start /unix '/home/WhatINamedThisPc/.wine/drive_c/Program Files (x86)/amnesia/rest/Launcher.exe' the exact path of that .exe could need either apostrophes or quotations depending on if it lives ín the same drive as Linux Mint...OR if it is a completely separate physical drive. cheers
Want to clear some kernels. Space? Sound (dummy terminal ). Desktop. Audio card analoge stereo. Have to show where sound is by unplugging and plugging.
soooo sooooo useful thanks a lot man I have an exam tomorrow . before I listened to this vidio I have zero idea about this freaking commands 😹😸 but now I'm a professional in 34min 😎💪 isn't it looks so great.
I love the entomology of sayings. I have always wondered where the saying " more than one way to skin a cat " came from. Seems brutal, or is it just me? And does anyone else visualize the cat as still being alive? Maybe that is why I see it as brutal. Good stuff. Your bash playlist is the best on the web. Thanks a bunch.

Some alternatives of some commands in this video for productivity killall -> xkill ls -l -> la (in some distroes) clear -> Ctrl + L ctrl + alt +f7 back to GUI from tty
"Shutdown -t 2" is useful for updating before bed. It'll finish the update and shutdown. For large updates I recommend "Shutdown -t 5" or 10 depending on the size of the update.
ok, interesting, i usually want to kill just one tree of processes. killing other peoples processes would cause problems. I would first, of course use ps -ef | grep (process name) | more to find the process i want to kill@@EzeeLinux
To kill FF while retaining all tabs, "killall -9 firefox" is helpful. Chromium is a bit trickier, though. This is what I do: alias kill_chromium='kill -9 `pgrep chromium`' which(1) says where *in your search path* the file is, not where it is. You need find(1) or locate(1) for that. I like mtr(1) instead of ping, because some sites block ICMP echo. What about "more longfile.txt"? "su - cindy" brings you to her $HOME, and in her context. "cd" is built into bash, so you type "help cd".
CTRL-ALT-T : usually 'open a new terminal', on most linux gui desktops. CTRL-D : how I usually close a terminal (on a blank line. It's the 'end of file' character, which tells bash that it's done, and it can shut itself down) cd : just cd by itself -> it's a shortcut which takes you to your home. No need to type 'cd ~' CTRL-Q ( if you accidentally hit CTRL-S when reaching for CTRL-D, it'll seem like it's frozen... because that's what CTRL-S does.... CTRL-Q tells it to continue) TAB : by far the most useful key, safe to press randomly / multiply. Will try to finish typing filenames or directories, but only as far as it can before there's a choice to make... double-TAB will make it display what choices there are -- type one more letter, then hit tab again. This last one makes the command line nice to use, because you won't have to be touch-typing perfectly all the time. Once you get used to it, the way tab-completion works on windows will annoy -- it's not nearly as nice to you, forcing you to sit there and hit it over and over again while it trys one file after another... So stupid! But that's the biggest difference between Linux and Windows. Annoying things aren't welcome.
"mkdir -p" is great for ensuring that a path exists in a script, because if any of the parent directories are missing it'll create them for you as well.
There is no man page for the 'cd' command... because it is a SHELL construct/command. Do a man on bash (or ksh, csh, ...) and you will find it explained there.
I might be wrong, but you could actually run 'touch {file1,file2,file3,etc}.txt' and it would create all the files separated by coma with the .txt at the end. Saves a whole bunch of time.
export PAGER=less The man command, among others uses this. Most Linux systems have it set this way, but you might find that it's something else on some systems. Also, I always thought it was funny that AIX hardware techs would use the really primitive pg command, which still exists, and is useful when working at the really, really low levels that hardware people often do.
Don't scare DOS people by talking about touch command! :D Well, IMHO it's most useful to test inside .BAT file (:D) if you have write permission to file/directory . I love shell scripts. Had to install WSL to my windows-PC at work to write script. And to compile some C. Of course I installed Linux on virtualbox (and other instance into real partition (and after that claimed to boss that I really need new SSD because I am running out of disk space) to feel as I were home. (Linux user since 1995. Yes, I am old). But I need to use f*king Autodesk apps at work, so windows is going to stay at that computer:( Cheese... starting to be too much drunk and hating windoze. Why not. Edit: Nice video. Satisfied my daily Linux needs. Subscribed. PS: Please do video about awk. That will really make GUI people go nuts!
10:00 it may install and not create a launcher .. and you have to know the name of the package .. and search where the hell it is.. there is no executable file as in windows for all are executable files in linux... tell me which f... folder has the executable. i am not sure if it has installed anything; if someone else- a hacker maybe- created a file it seems it would/may not prompt to ask a permission to install nor show to a basic user any sign of any software installed .. i would call that command wherethehell ... so primitive and exasperating an experience..i think, that's why many people prefer windows. nice video i like it, thank you.. but i did not like the idea of running after things in computer, like a mother running after a spoiled kid...
What you're talking about is an extremely rare thing. Yes, there is an executable file and yes you can easily create a launcher if it does. You just don't know how. A little research will take care of that. Plus, there are man y programs in Linux that are not designed to run from a menu but are for the command line only. they don't have launchers. Look before you leap when installing software. :)

to copy from terminal use ctrl+ shift+ c, to paste use ctrl+ shift+ v to open a new tab in terminal use ctrl+shift+t. to close a terminal tab use ctrl+ shift+ w.
thanks for the videos. have learned a lot from your channel. If I could just find my perfect distro now :) like debian neptune and mint (I am still newbie-but learning it. )
Hi Joe, I have a simple problem, if it's in Windows, it wouldn't be a problem. I use Linux Mint 18.1 and this is the scenerio: Nautilus told me I have an internal drive name ABC and a USB drive named DEF. I would like to copy file from drive ABC to drive DEF, how would I issue the command in Terminal??? Please help me! I am a Linux neubie. Thanks a lot, Joe.
One command I find odd that isn't installed is traceroute (I know there is a package you can install). That along with the ping tool are very much needed to find a fault in a connection to a server. It can tell where the "break" is. It's helped me on Windows systems to find out that a local server was down. (Corporate server in another location). The fix was to force a reroute to a backup server. The reason it wasn't automatic was because the other server was 3000 miles away and didn't have everything that was needed. It was better to see it down so that it could be fixed quickly.
Just a little thing with the whole 'less' & 'more' scrolling thing. You can also set buttons to scroll either a half-page or a full page. ex: my half page is 'Shift + Down', scroll full page down 'Shift + Alt + Down'. So if I want to be scrolling half pages I just push shift then the desired direction. For full-page scrolling, do shift+alt then up or down for faster scrolling works great for me!
9:50 The WHICH command relies on the PATH variable, it totally ignores other copies of the same executable file on your computer, if not specified in PATH. Actually, nobody says that the paths in your PATH variable actually exist. The main reason to use WHICH is when you have multiple copies of a same-named executable spread out over different structures (path). But, also having those paths in the PATH variable. The order determines which one is used.
Thanks a lot really appreciate it, outstanding tutorial. One question I am using centoOS however I forgot my root password how can I reset it please, Thanks
Man pages are great. I can't count how many times the man pages have been helpful. Do yourself a favor and get in the habit of reading the man pages of any program you install.
I learned the which command. I had always used the Find / -executable -name file.ext. Debian is the root operating system that many of the others are derived like ubuntu and mint. I also use apt-get and dpkgs for installing and removing packages.
I click on random links about Linux. Just to learn something new, or keep me refresh on commands I already know. That touch timestamp, I really didn't know that one. And will keep that fresh in my mind. That command can come in handy at times. Really like this video. So thumbs up.
Thats not true, If desktop hangs up you can bring up terminal or use tty terminal!! In 'kernel panic' situation nothing works !! You need to reboot only!!! Days are gone, when Desktoo GUI kept crashing.
I agree, looks more for beginners but that is fine. You gotta start some place and the CL gives you options and is very powerful tool in Linux. Don't be intimidated, learn these and then keep adding new ones...8-)
With the terminal in live boot I was able to remove a couple of files in my Pop-os install where I accidentally filled up the place with virtual disks of several GB and stopped the system with 0 bytes of free space. The startup worked after that. 7-8 GB of free space was required to show me a login. It's complicated to make oneself root/admin in Linux and give permission to be all over the place, but it worked and was funny to try and solve something like that. I think most terminal commands are well explained on the internet now.
The ctrl alt F4 real terminal has been a saver for me although on a serious hang the TTY has been slow to process the login before I'm able to type "reboot." I only learned recently that ctrl alt F4 followed by ctrl alt del cuts out the authentication and its wait to give a clean shutdown/reboot
As for "which" command, I didn't know that one but I use "whereis" This command will not just tell you where the launch file is but will tell you where all the files related to the program are. It will often give multiple directories for libraries and other related files.
Very gud. Presently i am working to take my Linux knowledge to the next level so hopefully this time next year i too will be capable of making videos like this!
The "cd" command is not a "basic system function". In most case it is an intrinsic function of the shell you're using. When you submit "man cd" in a bash you will be directed to the bash builtin man page.
My favorite use of touch is to match timestamps with other files: touch -r otherfile.txt And, there are reasons to get pedantic about the three different kinds of time stamps at the more advanced levels: ctime, mtime, and atime.
Very good tutorial! I'm a long time Linux user and just wanted to check out your lessons. I will definitely recommend you to some of my students who are looking to learn about Linux commands. Aloha!
+Ana Rita you're missing the point. The "dash" between su and Cindy saves you from having to change directories, set environment variables, etc. it allows the root user to completely assume the su'd user's account. I'm completely aware that root has to have complete access. I've spent over 25 years as a Unix system admin.
+Jeremy Nieuwoudt Ah, You are correct and I didn't point that out in the video... I responded to the comment from Ann without looking closely at the original. Thanks for the input. :)

would like to add this command
sudo !!
this will add sudo to the previous command and execute it, if u forgot to add root permission
That would have been useful earlier today... very, very useful...
for clearing instead of "clear", just use ctrl+L
That doesn't work on every terminal and I was trying to keep this video very close to the basics as possible. :)
clear will erase your scrollback so you may want to do ctrl+L instead to preserve your scrollback (same as clear -x)
The clear command only clears commands from the screen.
But if you use history -c, the c option means clear. this will clear everything you typed when you opened the terminal. But if you never use this command before and you think all the commands you have typed are gone by using the clear command then you are wrong. There is this file that keeps all the commands that you have used. This file is called .bash_histor. But that's when you exit the terminal. All the commands will save.
I prefer "reset"
Nice! I'm running WSL2 on Windows. Naturally, it works in my Linux environment, but it turns out that it works in PowerShell as well. But not cmd.
I know this is being picky, but sda1, sda2, sdb1, sdb2, etc are PARTITIONS, not drives. sda1 is partition 1 on physical drive sda, and sdb2 is a partition on physdical drive sdb. I think it's important to use the correct terminology, especially for the audience you're trying to reach.

Some commands needs you to do that
There is no man page for cd because cd is part of the shell and is documented in the bash or other shell man page.
Great video.
I just want to add a thing:
'cat' (abbreviation of concatenate) is actually used to concatenate (merge) two or more files.
For example: cat file1.txt file2.txt file3.txt file_n.txt
We can also redirect the output to, for instance, a file, like this:
cat file1.txt file2.txt file3.txt > file_1_2_3.txt
file_1_2_3.txt will consist of the contents of file1.txt, file2.txt and file3.txt
Again, great video. Keep em coming.
sksmd

It *can* be used that way, but its typical use is to print the contents of a single file to standard output (ie. the terminal).
cat is an abbreviation of catenate not concatenate.
Also > overwrites the file >> appends to the file

if it's native windows program or game..here's one way you can do that.
right click on your mint desktop..select " Create a launcher"
in the command field type the following info below at the beginning.
wine start /unix
note the one spacebar press between /unix and the exact path of the .exe file ans ensure one space bar press between wine and start .so an example could be
wine start /unix '/home/WhatINamedThisPc/.wine/drive_c/Program Files (x86)/amnesia/rest/Launcher.exe'
the exact path of that .exe could need either apostrophes or quotations depending on if it lives ín the same drive as Linux Mint...OR if it is a completely separate physical drive.

What is best software to use to make copy of Linux harddrive
The dd command. :)
There is no man page for the 'cd' command... because it is a SHELL construct/command. Do a man on bash (or ksh, csh, ...) and you will find it explained there.
True for all shell built-in commands. It's possible to learn a great deal by reading your shell's man pages.
help cd
"Greetings and salutations"... I loved Might and Magic 6 too back in the days.
It comes from when I was in school for radio... One of my teachers used to say that on the air. :)
I might be wrong, but you could actually run 'touch {file1,file2,file3,etc}.txt' and it would create all the files separated by coma with the .txt at the end. Saves a whole bunch of time.
Nope. You can do that with spaces as separators but not commas.. :)
@@EzeeLinux Ohhh right, haven't used that one in a long while, my bad xD
less is more
export PAGER=less
The man command, among others uses this. Most Linux systems have it set this way, but you might find that it's something else on some systems. Also, I always thought it was funny that AIX hardware techs would use the really primitive pg command, which still exists, and is useful when working at the really, really low levels that hardware people often do.
Awesome! I learned some new things today. Thanks. :)
Don't scare DOS people by talking about touch command! :D
Well, IMHO it's most useful to test inside .BAT file (:D) if you have write permission to file/directory .
I love shell scripts. Had to install WSL to my windows-PC at work to write script. And to compile some C.
Of course I installed Linux on virtualbox (and other instance into real partition (and after that claimed to boss that I really need new SSD because I am running out of disk space) to feel as I were home. (Linux user since 1995. Yes, I am old).
But I need to use f*king Autodesk apps at work, so windows is going to stay at that computer:(
Cheese... starting to be too much drunk and hating windoze. Why not.
Edit: Nice video. Satisfied my daily Linux needs. Subscribed.
PS: Please do video about awk. That will really make GUI people go nuts!
9:40 onwards= a headache saver for me. Thanks Joe
10:00 it may install and not create a launcher .. and you have to know the name of the package .. and search where the hell it is.. there is no executable file as in windows for all are executable files in linux... tell me which f... folder has the executable. i am not sure if it has installed anything; if someone else- a hacker maybe- created a file it seems it would/may not prompt to ask a permission to install nor show to a basic user any sign of any software installed .. i would call that command wherethehell ... so primitive and exasperating an experience..i think, that's why many people prefer windows. nice video i like it, thank you.. but i did not like the idea of running after things in computer, like a mother running after a spoiled kid...
What you're talking about is an extremely rare thing. Yes, there is an executable file and yes you can easily create a launcher if it does. You just don't know how. A little research will take care of that. Plus, there are man y programs in Linux that are not designed to run from a menu but are for the command line only. they don't have launchers. Look before you leap when installing software. :)
@@EzeeLinux o.k. :) even if i don't like it, i will learn it- now i will learn how to create laucher. i was looking for a feat for myself- linux first and pyhton 2nd. thank you for the info you have shared. have a lovely day.
to copy from terminal use ctrl+ shift+ c,
to paste use ctrl+ shift+ v
to open a new tab in terminal use ctrl+shift+t.
to close a terminal tab use ctrl+ shift+ w.
Once again, not in every terminal... :)
Joe Collins works in mint ☺
anyway, great videos
thanks for the videos. have learned a lot from your channel. If I could just find my perfect distro now :) like debian neptune and mint (I am still newbie-but learning it. )
You can also do a *search* with *less* (among other things), by pressing '/'
Hi Joe,
I have a simple problem, if it's in Windows, it wouldn't be a problem.
I use Linux Mint 18.1 and this is the scenerio:
Nautilus told me I have an internal drive name ABC and a USB drive named DEF. I would like to copy file from drive ABC to drive DEF, how would I issue the command in Terminal???
Please help me! I am a Linux neubie.
Thanks a lot, Joe.
One command I find odd that isn't installed is traceroute (I know there is a package you can install). That along with the ping tool are very much needed to find a fault in a connection to a server. It can tell where the "break" is. It's helped me on Windows systems to find out that a local server was down. (Corporate server in another location). The fix was to force a reroute to a backup server. The reason it wasn't automatic was because the other server was 3000 miles away and didn't have everything that was needed. It was better to see it down so that it could be fixed quickly.
Finished the vid. REally bare-bones list here, i dont think you can use linux without many of these. Very good for complete begginers, for sure.
Just a little thing with the whole 'less' & 'more' scrolling thing. You can also set buttons to scroll either a half-page or a full page. ex: my half page is 'Shift + Down', scroll full page down 'Shift + Alt + Down'.
So if I want to be scrolling half pages I just push shift then the desired direction. For full-page scrolling, do shift+alt then up or down for faster scrolling works great for me!
9:50 The WHICH command relies on the PATH variable, it totally ignores other copies of the same executable file on your computer, if not specified in PATH. Actually, nobody says that the paths in your PATH variable actually exist. The main reason to use WHICH is when you have multiple copies of a same-named executable spread out over different structures (path). But, also having those paths in the PATH variable. The order determines which one is used.
Thanks a lot really appreciate it, outstanding tutorial. One question I am using centoOS however I forgot my root password how can I reset it please, Thanks
Man pages are great. I can't count how many times the man pages have been helpful. Do yourself a favor and get in the habit of reading the man pages of any program you install.
I learned the which command. I had always used the Find / -executable -name file.ext.
Debian is the root operating system that many of the others are derived like ubuntu and mint.
I also use apt-get and dpkgs for installing and removing packages.
I click on random links about Linux. Just to learn something new, or keep me refresh on commands I already know. That touch timestamp, I really didn't know that one. And will keep that fresh in my mind. That command can come in handy at times. Really like this video. So thumbs up.
Thats not true, If desktop hangs up you can bring up terminal or use tty terminal!!
In 'kernel panic' situation nothing works !! You need to reboot only!!!
Days are gone, when Desktoo GUI kept crashing.
I agree, looks more for beginners but that is fine. You gotta start some
place and the CL gives you options and is very powerful tool in Linux.
Don't be intimidated, learn these and then keep adding new ones...8-)
With the terminal in live boot I was able to remove a couple of files in my Pop-os install where I accidentally filled up the place with virtual disks of several GB and stopped the system with 0 bytes of free space. The startup worked after that. 7-8 GB of free space was required to show me a login. It's complicated to make oneself root/admin in Linux and give permission to be all over the place, but it worked and was funny to try and solve something like that. I think most terminal commands are well explained on the internet now.
The ctrl alt F4 real terminal has been a saver for me although on a serious hang the TTY has been slow to process the login before I'm able to type "reboot." I only learned recently that ctrl alt F4 followed by ctrl alt del cuts out the authentication and its wait to give a clean shutdown/reboot
The "touch" command is probably one of the primary ways why you would need to use a terminal in the first place. Great one!
This reminds me of MS-DOS command prompt.
I need to pracice more of these on Linux.
As for "which" command, I didn't know that one but I use "whereis" This command will not just tell you where the launch file is but will tell you where all the files related to the program are. It will often give multiple directories for libraries and other related files.
I'm on a chromebook maybe next month ima get my first windows computer and the first thing I'm gonna do is open the terminal xd
Very gud. Presently i am working to take my Linux knowledge to the next level so hopefully this time next year i too will be capable of making videos like this!
I've had to use Ctrl Alt F4 a few times with MATE and would either do a Ctrl Alt Del or a shutdown command or reboot command.
Instead of typing "clear", try CTRL-L :)
I do./ It doesn't work in every terminal, though. That;s why I typed it in these videos. :)
Really? Never found a terminal it doesn't work in. It even works in Mac OSX bash. (except maybe putty.. which is just wrong ;)
The "cd" command is not a "basic system function". In most case it is an intrinsic function of the shell you're using. When you submit "man cd" in a bash you will be directed to the bash builtin man page.
Thanks again for the knowledge.
P.s. i dont skip your adds out of respect. Knowledge should be free but it isnt.
My favorite use of touch is to match timestamps with other files: touch -r otherfile.txt
And, there are reasons to get pedantic about the three different kinds of time stamps at the more advanced levels: ctime, mtime, and atime.
Great useful tips. Powerful stuff... Something Windows forbids its customers to obtain and maintain. 👍
Arrived here from another video where the comments exploded into a pronunciation war, bloody hilarious!!!
Very good tutorial! I'm a long time Linux user and just wanted to check out your lessons. I will definitely recommend you to some of my students who are looking to learn about Linux commands. Aloha!
su - cindy will allow you to log into Cindy's account AND take you to her home directory AND execute that account's login script.
+Jeremy Nieuwoudt Yes, the administrator has full access to everyone's account. That's how it should be. :)
+Ana Rita you're missing the point. The "dash" between su and Cindy saves you from having to change directories, set environment variables, etc. it allows the root user to completely assume the su'd user's account. I'm completely aware that root has to have complete access. I've spent over 25 years as a Unix system admin.
+Jeremy Nieuwoudt Ah, You are correct and I didn't point that out in the video... I responded to the comment from Ann without looking closely at the original. Thanks for the input. :)
