and 1 if false.
The following options are available:
- \c -h displays a help message and then exits.
- <tt>-L FILE</tt> returns true if \c FILE is a symbolic link.
- <tt>-S FILE</tt> returns true if \c FILE is a socket.
- <tt>COND1 -a COND2</tt> combines two conditions with a logical and.
- <tt>-b FILE</tt> returns true if \c FILE is a block device.

- <tt>-d FILE</tt> returns true if \c FILE is a directory.
- <tt>-e FILE</tt> returns true if \c FILE exists.
- <tt>-f FILE</tt> returns true if \c FILE is a regular file.
- <tt>-f FILE</tt> returns true if \c FILE has set-group-ID bit set.
- <tt>-n STRING</tt> returns true if the length of \c STRING is non-zero.
- <tt>COND1 -o COND2</tt> combines two conditions with a logical or.
- <tt>-p FILE</tt> returns true if \c FILE is a named pipe.
- <tt>-r FILE</tt> returns true if \c FILE is readable.

\subsection test-example Example
<pre>
if test -d "/"
echo "Fish is cool"
end
if test -d "/"
echo "Fish is cool"
end
</pre>
Because "/" is a directory the expression will evaluate
to true, and "Fish is cool" will be echoed
Because "/" is a directory, the expression will evaluate to true, and
"Fish is cool" will be output.
