Hi there,

I found what I think is a bug in the *md5sum* command.

When used on a filename with a backslah, the output doesn't look quite the
same as usual:

# ls -l /tmp/file1 '/tmp/file\2'
-rw-r--r-- 1 root root 2 2012-04-30 17:05 /tmp/file1
-rw-r--r-- 1 root root 2 2012-04-30 17:05 /tmp/file\2
# md5sum /tmp/file1 '/tmp/file\2'
60b725f10c9c85c70d97880dfe8191b3  /tmp/file1
\3b5d5c3712955042212316173ccf37be  /tmp/file\\2

Hope this helps

Thanks for the report.  However, this is not a bug, but intentional
behavior.  It allows us to encode filenames with newlines in them using
a \n sequence, but to use \ as an escape character, \ also has to escape
itself.
