<p>How do you find the version of an installed Perl module?</p>

<p>This is in an answer down at the bottom, but I figure it important enough to live up here.  With these suggestions, I create a function in my <code>.bashrc</code></p>

<pre><code>function perlmodver {
    perl -M$1 -e 'print "Version " . $ARGV[0]-&gt;VERSION . " of " . $ARGV[0] . \
    " is installed.\n"' $1
}
</code></pre>

Most modules (especially ones from The CPAN) have a $VERSION variable:
```
```
perl -MSome::Module -le 'print $Some::Module::VERSION'
```
```
