The following will not work if you have line breaks in you file names, but if you do
have that, you may want to rethink that as it will usually cause problems for programs,
especially for shell scripts.
The command @command{__pony=$(ponysay -o 3>&1 1>/dev/null | grep ^pony\ file: |
sed -e s/^pony\ file:\ //g) && (ponysay -of "$__pony" | ponythink -Wi -f "$__pony")}
will give you a pony thinking of herself. The command works on GNU Bash, but my
not work one less POSIX compatible shells. It works by first getting a random
pony and use the extra information printed the file descriptor 3 (see @ref{Extra information}),
and fetchs the file name with help of @command{grep} and @command{sed}. The file
name is stored in a shell variable. It the pipes one an execute of ponysay into
another executing, using the stored file anme in both executions.
Ponysay can use just about anything as a message because it quarantines the message's
ANSI escape sequences, including colour. And is Unicode aware (including combining
characters) and ANSI escape sequence aware.
Naturally this means that you can also make ponies think of eachother,
for example: @command{ponysay -f rarity -b round 'My little Spiky-wiky' |
ponythink -f spikefloat -b unicode -W n}

To make it easier to write auto-completion for shells, @command{ponysay} supports

which has no short versions. To make it even easier we use @command{auto-auto-complete}
