Is there a way to let the gdb repeat the same instrcutions on every start again?
I am currently debugging a program with gdb. I have to start gdb over and over again and do the same steps:
set a breakpoint, run, print a variable, quit
Is there a way to let gdb do that automatically for me? Probably a script that could be 开发者_开发问答attached as a parameter?
Thanks in advance!
You can do it either by -x file
option or by -ex command
option. From Gdb manual:
-command file
-x file
Execute commands from file file. The contents of this file is evaluated exactly as the source command would. See Command files.
-eval-command command
-ex command
Execute a single gdb command.
This option may be used multiple times to call multiple commands. It may also be interleaved with `-command' as required.
gdb -ex 'target sim' -ex 'load' \
-x setbreakpoints -ex 'run' a.out
The interwebs differ on whether the name of the file is .gdbrc or .gdbinit, but GDB will read this file from your home directory on start-up, and it can give any GDB command (including setting breakpoints).
