If you're willing to accept bashisms, then:
argstr=""
for arg in "$@"; do
argstr=${argstr:+$argstr,}arg=${arg//,/,,}
done
qemu-system-arm --semihosting-options "$argstr"
If you want pure POSIX shell then it is slightly
uglier as we have to invoke sed:
argstr=""
for arg in "$@"; do
o=$(printf '%s.\n' "$arg" | sed s/,/,,/g)
argstr=${argstr:+$argstr,}arg=${o%.}
done
qemu-system-arm --semihosting-options "$argstr"
(Note the trick with the '.' to ensure correct handling
of trailing newlines in arguments; credit to mdw for
that one.)
