gdb -ex 'target sim' -ex 'load' -ex 'run' a.out. -batch. Run in batch mode. Exit with status 0 after processing all the command files specified with ‘-x’ (and all commands from initialization files, if not inhibited with ‘-n’). -p number. Connect to process ID number, as with the attach command.
Tracepoints (Debugging with GDB) - sourceware.org
https://sourceware.org/gdb/onlinedocs/gdb/Tracepoints.html
Using GDB’s trace and collect commands, you can specify locations in the program, called tracepoints, and arbitrary expressions to evaluate when those tracepoints are reached. Later, using the tfind command, you can examine the values those expressions had when the program hit the tracepoints.
Stack trace with GDB - Mostly Machine Learning

Below is a single command that runs a program under GDB, stops when the program receives a signal other than SIGALRM or SIGCHLD, and prints the stack backtrace of all the threads: $ gdb -q \ -batch \ -ex 'set print thread-events off' \ -ex 'handle SIGALRM nostop pass' \ -ex 'handle SIGCHLD nostop pass' \ -ex 'run' \ -ex 'thread apply all backtrace' \ --args \ my …

GDB (Step by Step Introduction) - GeeksforGeeks

GDB stands for GNU Project Debugger and is a powerful debugging tool for C(along with other languages like C++).It helps you to poke around inside your C programs while they are executing and also allows you to see what exactly happens when your program crashes. GDB operates on executable files which are binary files produced by compilation process.
How to Debug Using GDB - Baylor University
https://cs.baylor.edu/~donahoo/tools/gdb/tutorial.html
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.
Backtrace (Debugging with GDB) - sourceware.org
https://sourceware.org/gdb/onlinedocs/gdb/Backtrace.html
A backtrace is a summary of how your program got where it is. It shows one line per frame, for many frames, starting with the currently executing frame (frame zero), followed by its caller (frame one), and on up the stack. To print a backtrace of the entire stack, use the backtrace command, or its alias bt. This command will print one line per frame for frames in the stack.

Debugger is a good tool for tracing bugs. In this tutorial, we will show you how to use gdb -- a "GNU" debugger. Compiling programs to run with gdb: Below is a not-so-well written program which reads a number n from standard input, calculates the sum from 1 to n and prints out the result: 1 #include <stdio.h>

GDB Tracing Commands Tracing program execution: the record/playback model Some program behaviors can be analyzed only by collecting data over long periods of time for later analysis. Other problems occur in sections of code that are too time-sensative to be debugged interactively.
