title: How can I use Perl to get a SHA1 hash of a file from the Windows command line?
body: <p>I have a file called <em>secure.txt</em> in <em>c:\temp</em>.  I want to run a Perl command from the command line to print the SHA1 hash of <em>secure.txt</em>.  I'm using ActivePerl 5.8.2.  I have not used Perl before, but it's the most convenient option available right now.</p>
