gdb command in Linux with examples - GeeksforGeeks
September 2, 2024 - For example, in the above execution, the breakpoint is kept at function findSquare and the program was executed with the arguments "1 10 100". When the function is called initially with a = 1, the breakpoint happens. Now we create a checkpoint and hence gdb returns a process id(4272), keeps it in the suspended mode and resumes the original thread once the continue command is invoked.

GDB can run on most popular UNIX and Microsoft Windows variants, as well as on macOS.
How many of you actually use GDB from the terminal?
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 More on reddit.com

The purpose of a debugger such as GDB is to allow you to see what is going on "inside" another program while it executes -- or what another program was doing at the moment it crashed. GDB can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: • Start your program, specifying anything that might affect its behavior.

March 18, 2024 - Since we’re going to do post-release debugging, we should first compile our example. To that end, we’ll use gcc (GNU C Compiler). To make full use of GDB, it’s best we compile with the -g or -ggdb flags to gcc.

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.?
