It's a way of getting sha sums for a file.  I've been carrying those
in my .bashrc file for ages.. I don't remember if I didn't know about
the sha1sum program or it didn't exist in cygwin at the time, but I
found a method that worked and quit looking.  By now it's "muscle
memory" -- like returning from vacation and not being able to remember
your password, but go down to the cafeteria, get a cup of coffee,
return to your desk, turn your PC on and enter your password without
thinking.  I found a method that worked and don't think about it any
more.  You probably should use the sha1sum, sha256sum, sha512sum
programs though - if only to reduce confusion when you're talking to
other people :)
