Once the command is successful, it prints the breakpoint number, information of the program counter, file name, and the line number. The program pauses whenever the function is called. In the above example, the program that was being executed( run 10 100), paused when it encountered findSquare function call. b findSquare command makes the gfg executable pause when the debugger starts to execute the findSquare function.īreak ***any of the above arguments*** if Multiple breakpoints can be inserted by executing the command wherever necessary. It helps to debug the program at that point.

break : The command break helps to pause the program during execution when it starts to execute the function.

help : It launches the manual of gdb along with all list of classes of individual commands.

quit or q : To quit the gdb console, either quit or q can be used.

In the below image, the program was executed twice, one with the command line argument 10 and another with the command line argument 1, and their corresponding outputs were printed.

run : This command runs the current executable file.

It opens the gdb console of the current program, after printing the version information.

To start the debugger of the above gfg executable file, enter the command gdb gfg. AWK command in Unix/Linux with examplesĬompile the above C++ program using the command: g++ -g -o gfg gfg.cpp.Sed Command in Linux/Unix with examples.
