|
<p>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.
|
|
</p>
|
|
<p>The command <code>__pony=$(ponysay -o 3>&1 1>/dev/null | grep ^pony\ file: |
|
|
sed -e s/^pony\ file:\ //g) && (ponysay -of "$__pony" | ponythink -Wn -f "$__pony")</code>
|
|
will give you a pony thinking of herself. The command works on GNU Bash, but may
|
|
not work on less POSIX compatible shells. It works by first getting a random pony and
|
|
use the extra information printed the file descriptor 3 (see <a href="Extra-information.html#Extra-information">Extra information</a>),
|
|
and fetchs the file name with help of <code>grep</code> and <code>sed</code>. 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. This does not
|
|
work on FISH shell because os POSIX incompatibility.
|
|
</p>
|
|
<p>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.
|
|
</p>
|
|
<p>Naturally this means that you can also make ponies think of eachother,
|
|
for example: <code>ponysay -f rarity -b round 'My little Spiky-wiky' |
|
|
ponythink -f spikefloat -b unicode -W n</code>
|
|
