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. sl is a highly advanced animation program for curing your bad habit of mistyping.
Install sl software to get Steam Locomotive ( train in shell )
Type the following apt-get command/apt command on a Debian / Ubuntu Linux:
$ sudo apt-get install sl
Type the following yum command on a CentOS/RHEL (first enable EPEL repo on a RHEL/CentOS version 6 or version 7 of CentOS/RHEL):
$ sudo yum install sl
Type the following dnf command on a Fedora Linux:
$ sudo dnf install sl
Type the following brew command on a macOS Unix desktop:
$ brew install sl
Type the following pkg_add command on a OpenBSD:
# pkg_add -v sl
Type the following pkg command on a FreeBSD:
# pkg_add -v sl
Okay, just 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.
And there you have it, sl displays animations (train in shell) aimed to correct users who accidentally enter sl instead of ls for fun and profit. If you enjoyed this desktop fun app, you may also like to use the following apps on Linux:
