- 'Ctrl+x 1' to enter the TUI mode.
- 'Ctrl+x o' to shift between windows
- 's' or 'step' to step into the source code.
- 'br' or 'break' to set a breakpoint followed by a line number or function name
- 'c' or 'continue' to continue from a breakpoint.
- 'set var=value' to set a varaible value.
- 'p' or 'print' followed by a variable. Note: You can also dereference a variable (e.g. print *px) to see the dereferenced value.
- 'bt' or 'backtrace' to get the stack frame.

This was very helpful, thanks a lot! I'm learning C at the moment, and I used a debugger only a couple times before, inside an IDE. The fact that it's possible to debug through a terminal without so much pain is mind-blowing!

[@MikeShah]

Agreed, it's super powerful and my primary means of debugging now :D

For windows gdb - help (I have 7.6 version approximately 10 years old)
but -help just lists available options and it is not enough for me

[@MikeShah]

Hmm, are you able to run gdb ./executable_name ? From within gdb you can also do 'help' as well
