Re: md5sum: Output format error on files with backslash in their names

[Steven Augart]

Dear W. Limmer,

I can reproduce the output you sent.

I examined the md5sum documentation, and it is indeed incomplete.  "For 
each file, `md5sum' outputs the MD5 checksum, a flag indicating binary or 
text input file, and the filename. " 

It seems clear that this whole backslashing thing is done in order to 
handle the case of a filename that contains a newline (since the format 
uses newlines as terminators), and once that's in place, to handle the 
case of a filename that contains the string "\n".  (I looked in the source 
code, src/md5sum.c, to check.)

maintainer(s): Does it make sense for one of us to add documentation on 
the file format output by md5sum to the information on the texinfo page?

backslash in their names


Dear Team,

using md5sum on files with a backslash in their filenames 
gives an error in the output file format: A waste backslash
is output at the beginning of the line.

Also the backslashes themselves are quoted: Bug or feature?

Please check following example:

> md5sum ../div/Üble\ Filenamen/*
\45bb8963e53c01e2fd6f926bc15f0553  ../div/Üble Filenamen/with\nLinefeed
\d41d8cd98f00b204e9800998ecf8427e  ../div/Üble Filenamen/with \\ Backslash
\d41d8cd98f00b204e9800998ecf8427e  ../div/Üble Filenamen/with \\\\ 
Backslashes
a6a218b4d55f251551f21ac351bded8e  ../div/Üble Filenamen/äöü?
...

Best regards,
W. Limmer
