Cowsay

cowsay is a program that generates ASCII art pictures of a cow with a message. It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot. It is written in Perl. There is also a related program called , with cows with thought bubbles rather than speech bubbles. .cow files for cowsay exist which are able to produce different variants of cows, with different kinds of eyes, and so forth. It is sometimes used on IRC, desktop screenshots, and in software documentation. It is more or less a joke within hacker culture, but has been around long enough that its use is rather widespread. In 2007, it was highlighted as a Debian package of the day.

Example The Unix command can also be piped into the command: [user@hostname ~]$ fortune | cowsay ________________________________________ / You have Egyptian flu: you're going to \ \ be a mummy. /

\ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w |

Using the parameter followed by , one can replace the cow with other beings, such as Tux, the Linux mascot: [user@hostname ~]$ fortune | cowsay -f tux _________________________________________ / You are only young once, but you can \ \ stay immature indefinitely. /

\ \ .--. |o_o | |:_/ | // \ \ (| | ) /'\_ _/`\ \___)=(___/

Using the parameter shows all available cow files: [user@hostname ~]$ cowsay -l Cow files in /usr/share/cowsay/cows: apt bud-frogs bunny calvin cheese cock cower daemon default dragon dragon-and-cow duck elephant elephant-in-snake eyes flaming-sheep fox ghostbusters gnu hellokitty kangaroo kiss koala kosh luke-koala mech-and-cow milk moofasa moose pony pony-smaller ren sheep skeleton snowman stegosaurus stimpy suse three-eyes turkey turtle tux unipony unipony-smaller vader vader-koala www

Parameters Option Purpose -n Disables word wrap, allowing the cow to speak FIGlet or to display other embedded ASCII art. Width in columns becomes that of the longest line, ignoring any value of . Only works with text from stdin. -W Specifies width of the speech balloon in columns, i.e. characters in a monospace font. Default value is 40. -b “Borg mode”, uses in place of for the cow′s eyes. -d “Dead”, uses , plus a descending to represent an extruded tongue, also used on Linux kernel oops. -g “Greedy”, uses . -p “Paranoid”, uses . -s “Stoned”, uses to represent bloodshot eyes, plus a descending to represent an extruded tongue. -t “Tired”, uses . -w “Wired”, uses . -y “Youthful”, uses to represent smaller eyes. -e eye_string Manually specifies the cow′s eye-type, e.g. (see Eastern-style emoticon).Characters other than printable in C0 controls and basic Latin (U+0021–U+007E) will not display properly as these parameters accept only the first two bytes of input value. Using a pre-defined cow-face will over-ride any value of and . -T tongue_string Manually specifies the cow′s tongue shape, e.g. for a pair of parentheses. -f cowfile Specifies a .cow file from which to load alternative ASCII art. Accepts both absolute file-paths and those relative to the environment variable . -l Lists the names of available cow-files in the directory instead of displaying a quote.
