problem with echoing script variable to gpg

2008-12-18 Thread pwaugh 

While this shell command

echo -n "net.berrysoft.dib.Game" | gpg --print-md sha1

gives me the correct response, when I try to do this in a script using ${1}:

digest = $( echo -n ${1} | gpg --print-md sha1 )
echo digest

I do not get the same value  I have no clue why.  Help.

Too much whitespace, and a misunderstanding about how shell variables
work.  You want:

digest=$( echo -n "$1" | gpg --print-md sha1 )
echo "$digest"

Don't work too hard, make some time for fun as well!

Thanks.  Amazingly, I got it figured out shortly after, and works like
a charm now.
