One of the most common mistake is typing sl instead of ls command. I actually set an alias i.e. alias sl=ls; but then you may miss out the steam train with whistle.
sl is a joke software or classic UNIX game. It is a steam locomotive runs across your screen if you type "sl" (Steam Locomotive) instead of "ls" by mistake.
Type the following command under Debian / Ubuntu Linux, enter:
# apt-get install sl
It is also available on FreeBSD and other UNIX like operating systems. Next, mistyped ls command as sl:
It also supports the following options:
- -a : An accident seems to happen. You'll feel pity for people who cry for help.
- -l : shows little one.
- -F : It flies.
- -e : Allow interrupt by Ctrl+C.
