Systemwide scripts

This is the diff between the backup and the current copy.

# Systemwide Sscripts

I have added a few very basic system-wide scripts to `/usr/local/bin`. These include some of the basic commands proposed by the motdessage of the day (`/etc/motd`). Some of them just provide a more common name for a specific app, e.g. `email` will start `mutt`, `forums` will start `tin`.


*Thinks to keep in mind:*

Q: Why not use aliases for this?

A: Users might not use the shell you created the alias for. A user using `fish` won't be able to use a `bash` alias.

Q: Why `email` and not just `mail`?

A: Because that already is taken by the program `mail`. Before setting a new script name better check it won't reuse the same name a different app uses.
