\subsection test-example Example
|
|
|
|
|
|
2012-11-05 01:38:42 +00:00
|
|
|
<pre>
|
|
|
|
|
if test -d "/"
|
|
|
|
|
echo "Fish is cool"
|
|
|
|
|
end
|
|
|
|
|
</pre>
|
2012-07-03 21:54:00 +00:00
|
|
|
|
|
|
|
|
Because "/" is a directory the expression will evaluate
|
|
|
|
|
to true, and "Fish is cool" will be echoed
|
