Shell commands
==============
If you need to execute occasional shell commands during your
debugging session, there is no need to leave or suspend GDB; you can
just use the `shell' command.
`shell COMMAND STRING'
Invoke a the standard shell to execute COMMAND STRING. If it
exists, the environment variable `SHELL' determines which shell to
run. Otherwise GDB uses `/bin/sh'.
The utility `make' is often needed in development environments. You
do not have to use the `shell' command for this purpose in GDB:
`make MAKE-ARGS'
Execute the `make' program with the specified arguments. This is
equivalent to `shell make MAKE-ARGS'.
