The reason why I don't use "$@" is that the arguments to the bash script is
not completely those for the executable. Some of them are just arguments
only to the bash script. So actually the script is like
[code]
#!/bin/bash
DEBUGGER=""
ARG_OPTS=""
while [[ -n "$1" ]];
case $1 in
--run)
make clean
make -j -k || exit 1
DEBUGGER=""
;;
--gdb)
make clean
make -j -k DEBUG=yes || exit 1
DEBUGGER="gdb --args"
;;
*)
ARG_OPTS="${ARG_OPTS} $1"
;;
esac
shift
done
${DEBUGGER} my_executable ${ARG_OPTS}
[/code]
