How do I run a program with commandline args using gdb within a bash script?
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.
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
-, 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.
