I am adding an option to md5 to reverse the order of output.
From: MD5 (/COPYRIGHT) = 7df8bc77dcee71382ea73eb0ec6a9243
to: MD5 7df8bc77dcee71382ea73eb0ec6a9243 /COPYRIGHT
The reson for this addition is to aid visual diffs. They are much easier if the MD5 hashes are nicely lined up.
I don't understand the issue. If you're going to compare
MD5 (/dev/null) = d41d8cd98f00b204e9800998ecf8427e and MD5 (/dev/null) = 93b885adfe0da089cdf634904fd59f71
They are already lined up. If instead you want to compare something like
MD5 (foo) = d3b07384d113edec49eaa6238ad5ff00 MD5 (quux) = d3b07a382ec010c01889250fce66fb13 to MD5 (foo) = 1bfe5d8702009e431bad3862b79f5d95 MD5 (quux) = 8687c409c3cc95464d49a7c4dff71e73
They're less lined up, but they look a lot better to a human than
MD5 1bfe5d8702009e431bad3862b79f5d95 foo MD5 8687c409c3cc95464d49a7c4dff71e73 quux
If for some reason we _really_ need this, what's wrong with a shell transformation instead:
transform_md5 () { local line while read line; do printf "MD5\t%s\t%s\n" $(echo "$line" | cut -d' ' -f4) \ done }
{"/home/green"}$ md5 /dev/null | transform_md5 MD5 d41d8cd98f00b204e9800998ecf8427e /dev/null
What good is all the convenience we have available to reduce bloat if we never use it for anything?
My question is what flag to use. "-r" for reversed output? "-v" for visual diff?
