RDSH - Random Shell

RDSH is a shell that picks a random shell on your system and runs with it. By default it uses login shells defined under /etc/shells

You can modify the shells by creating a ~/.rdshenv file

if you define multiple envs (e.g., ~/.rdshenv, ~/.rdshenv2, ~/.rdshenv3), RDSH will run one at random.

RDSH will also look for a system wide config (/etc/rdshenv*) and run one at random.

The -l and -n options exist, -l for listing the selection of shells, and -n for picking one without executing it.

The shell is entirely written in bash.

please add it to your path, or even better, use it as your login shell chsh -s "$(which rdsh)".

Read through the source code to understand your options.
