GDB Quick Guide
I found out I didn't need cgdb by the way, it was better to just gdb -tui on Debian. Less modem noise in the form of uninterpreted escape sequences too.
So it paid up to do gdb -help.
The guide doesn't mention watch or watch -l but it points to Debugging with GDB where you can find everything.
It is a good quick start, with a couple of examples.

Hello. So, by no means a pro yet, but I feel I have researched the subject enough to practice, and I have. So, those three blogs from Red Hat, concerning using Gdb instead of printf statements, where wildly interesting, I'm not sure how much time the technique saves, but I guess it saves some, and I also guess, while I write that this way of getting output doesn't disappear with screen refreshes. (The articles also show how to make your breakpoints reusable by the "save breakpoints" command, so you can edit them and reuse them for next session.) (The "#" works for a comment in the ini file, so I guess it also works for commenting out in breakpoint files you source in, so that some "break point commands" can be disabled). It's great even if it isn't Turbo Debugger, which was more visual, but you can break on values, and reuse your breakpoint commands, so in the end I feel having something not inferior. Part 1 Part 2 Part 3 And well, its a complex program, and I will eventually read the info manual, no matter how much I hate the info manuals, because this is a must. The --core command line options which lets you load a coredump from when your program crashed, and you can view values and see the stack trace, that feature justifies everything. IMHO. Oh, and on some slides from the University of Maryland, I learned about the "finish" command that finishes the current function you are in. :)

Getting Started with gdb C and C++ programs compiled with the GNU compiler and the -g option can be debugged using GNU's debugger gdb (actually, you can use gdb on code that is not compiled with -g, but unless you like trying to figure out how assembly code sequences map to your source code I wouldn't recommend doing so).

Before invoking the debugger. make sure you compiled your program (all its modules, as well as during linking) with the "-g" flag. Otherwise, life will be tough. Lets compile the "debug_me.c" program, and then invoke "gdb" to debug it:

If you want to know where you are in the program's execution (and how, to some extent, you got there), you can view the contents of the stack using the backtrace command as follows: (gdb) bt #0 ComputeFactorial (number=0) at broken.cpp:7 #1 0x08048907 in ComputeSeriesValue (x=3, n=2) at broken.cpp:21 #2 0x08048a31 in main () at broken.cpp:43

It’s a good habit to always use these options.) The -g option puts debugging information into the executable. Most importantly, it puts the text of the source code file into the executable so you can examine it as the program executes (we’ll see how below). Type gdb myprog (for the example above).

Curious how many of you use raw GDB when debugging C programs. Is it worth learning? Or is it better to find some front end program with buttons / watch-windows etc.?

I only use gdb and printf.

I use it in the terminal, but unless I'm just getting a backtrace from a core dump (most common use case), I usually press Ctrl-X A to enable eXtra-Awesome mode (I don't think it's actually called eXtra-Awesome mode, but that's how I remember the keystroke). I very rarely am stepping through code with gdb though, I tend to rely on printf's or just thinking really hard more often. Edit: looked it up, it's apparently called TUI mode
