SL (Steam Locomotive) runs across your terminal when you type "sl" as you meant to type "ls". It's just a joke command.

Copyright 1993,1998,2014 Toyoda Masashi ([email protected])

Usage: sl [OPTIONS]

Options:
  -a, --accident  An accident is occurring. People cry for help. Lists all files
  -l, --logo      Little version
  -F, --fly       It flies like the galaxy express 999
  -c, --c51       C51 appears instead of D51
  -f, --files     Disables listing files and directories
  -h, --help      Print help
  -V, --version   Print version

SL supports piping contents into it for printing things to the train car.

echo "Hello\nworld!" | sl

You can also pipe long/slow (only so slow though, if the train finishes before it gets a new line things are boring) running processes into it:

# Print package names as they are built as train cars!
cargo build 2>&1 | awk -F' ' '/Compiling/ {print $2}' | sl

You can embed the SL terminal in your own pages using query parameters:

Supported query parameters:

• accident: true or false
• fly: true or false
• smoke: true or false
• trainType: d51, c51, or logo
• messages: URL encoded JSON array of messages
