Debugging Commands

 

Here are some common commands used in GDB (GNU Debugger):

• run: starts the program being debugged
• break [file:]line: sets a breakpoint at the specified line in the current file or in the specified file
• info breakpoints: lists all breakpoints
• delete [breakpoint-number]: deletes a breakpoint
• continue: continues execution until the next breakpoint or the end of the program
• next: executes the next line of the program, stepping over function calls
• step: executes the next line of the program, stepping into function calls
• backtrace: displays a stack trace of the current execution state
• print [variable-name]: prints the value of the specified variable
• help: displays a list of commands or information about a specific command
• quit or q: exits GDB

Note: gdb has a lot more command to debug and inspect, These are the most common and useful command which is used to debug C/C++ programs.
