C Programming using getopt Tutorial in Linux

[@Joao-oj6bn]

Even after 8 years still the best video i can find about this subject, thanks!

[@TheLordoftheDarkness]

Thank you so much for explaining things slowly. All other tutorials I found on the Internet directly went to the ':' thing leaving me clueless. You video was very well presented on the other hand. Again thanks.

[@theurbanpenguin]

Glad it worked for you

[@NeoColossus1020]

Keep up the good work. I browse your videos from time to time and you always have a very direct/simple approach to explaining the concepts covered.

[@dampdigits]

Thank You! I was having difficulty to understand the concept from articles.

[@theurbanpenguin]

Thanks

@@theurbanpenguin why use getopt.h instead of unistd.h header file

Andrew - great video. Your truly passionate about sharing your knowledge. Keep up the great work. I learn a lot from watching your videos. Especially the C programming on RASPI. thanks, 73, N0AGI, Nagi

Bro, super good, thank you. I was writing copy of grep and don't know how to parse multiple flags so easy!

[@multivalfran]

Great video! getopt made simple !!!

[@D3rMesaa]

Ja geil, da hat der Kranzlmüller ja lang gesucht, bis er seine Aufgabe gefunden hat

[@shiftrip]

Great video. I'm a c novice so here's my question - if option is int, why does compiler allow us to option=getopt(argc....) when what we are reading from command line are characters (c or f) and not integer numbers?

[@codesk5653]

Hi there...
Thank for this video, it is extremely easy to follow along and understand. However, if the input is ./temp -fc the program takes 'c' as the ...How would I ensure that it still checks the flags/options in this case?

[@yogpooja-vq1pp]

very well explained .. thank you

[@theurbanpenguin]

Thanks for commentiing

[@shyngysbek6907]

option is declared as an integer but assigned a char symbol from the getopt and used in switch()? What?

[@shyngysbek6907]

ok, getopt returns an integer but it is represented as a char by its ASCII value

[@chandrashekharjp3044]

Great Tutorial :)

YOU SAVED ME

[@williamsilva8779]

thank you

[@shrutiambashtha6196]

Thank u sooooooo much ☺️☺️☺️

[@rafidm6263]

is there a particular reason why the flags aren't boolean?

[@samehmouldi2289]

how does the program know that cflag and flag reffer to the number of options please ?

[@miguelboxer177]

Why did you increment c and f flag?

[@Submersed24]

char **argv is the same as char *argv[] right?

[@hro688]

yes ofc. ** is the pointer to pointer, so char ** and char * [] is an array (or a pointer on the first element of this array) of "c-style" strings, because every string is c is just an array of char symbols with the 0 symbol at the end.

[@kumaravelrajan]

Perfect.

[@piacare]

8:56 did you start recording at night? Haha

[@timgoppelsroeder121]

that penguin is the shit!!!!!

[@luciomorra6174]

Didnt understand the fflag & cflag ...:(

[@SepidehAsadi1]

Thanks! It would be useful if you provide the text of code below the video link.

[@hro688]

спасибо, бро! Сними видео про getopt_long(), плизки! ставлю лайкос! успехов!

[@FERCHOLO0730]

awesome! however I played it 1.5x XD

[@Isaac-eh6uu]
