arguments How do I run a program with commandline args using gdb within a bash script?

3 Answers

gdb -ex=r --args myprogram arg1 arg2

-ex=r is short for -ex=run and tells gdb to run your program immediately, rather than wait for you to type "run" at the prompt. Then --args says that everything that follows is the command and arguments, just as you'd normally type them at the commandline prompt.

gdb set args example

When running a program on gdb, usually, the arguments for the program are given at run command. Is there a way to run the program using gdb and as well as give arguments within a shell script?

I saw an answer in a related question, mentioning that we can attach the gdb to the program after script starts executing. But then I will have to 'wait' the program.

I'm curious whether there is any other way to do this.

You could create a file with context:

run arg1 arg2 arg3 etc

program input

And call gdb like

gdb prog < file

An addition to the answer of Hugo Ideler. When using arguments having themself prefix like -- or -, I was not sure to conflict with gdb one.

It seems gdb takes all after args option as arguments for the program.

At first I wanted to be sure, I ran gdb with quotes around your args, it is removed at launch.

This works too, but optional:

gdb --args executablename "--arg1" "--arg2" "--arg3"

This doesn't work :

gdb --args executablename "--arg1" "--arg2" "--arg3" -tui

In that case, -tui is used as my program parameter not as gdb one.
