I would like to generate some exit code, say 20.
But if I do on shell:
$ exit 20
the shell is closed (X-Windows case) or I am logged out (text console case). Of course, inside .sh scripts, this command works fine.

$ return 20 bash: return: can only `return' from a function or sourced script $ break 20 bash: break: only meaningful in a `for', `while', or `until' loop
Is there any way to assign a value to
