<tt>if CONDITION; COMMANDS_TRUE...; [else; COMMANDS_FALSE...;] end</tt>
\subsection else-description Description
<tt>if</tt> will execute the command CONDITION. If the condition's exit
status is 0, the commands COMMANDS_TRUE will execute. If it is not 0 and
<tt>else</tt> is given, COMMANDS_FALSE will be executed. Hint: use
<a href="#begin"><tt>begin; ...; end</tt></a> for complex conditions.
<tt>if</tt> will execute the command \c CONDITION. If the condition's exit
status is 0, the commands \c COMMANDS_TRUE will execute. If it is not 0 and
<tt>else</tt> is given, \c COMMANDS_FALSE will be executed.
\subsection else-example Example
The command <tt>if test -f foo.txt; echo foo.txt exists; else; echo foo.txt does not exist; end</tt>
will print <tt>foo.txt exists</tt> if the file foo.txt
exists and is a regular file, otherwise it will print
<tt>foo.txt does not exist</tt>.
The following code tests whether a file \c foo.txt exists as a regular file.
<pre>
if test -f foo.txt
echo foo.txt exists
else
echo foo.txt does not exist
end
</pre>
