Hi, The following: sort < mifluz.dict -t ' ' -k 2n,2n > mifluz.dict.sorted fails when mifluz.dict is large enough to trigger the use of temporary files. Each temporary file is properly sorted by the resulting output is *not* sorted numerically on the second field. This bug only shows in textutils-2.0a sort. The same command works well with the textutils-2.0 sort. Thanks, FYI: textutils-2.0a is shipped with RedHat-6.2. -- Loic Dachary http://www.dachary.org/ [EMAIL PROTECTED] 24 av Secretan http://www.senga.org/ [EMAIL PROTECTED] 75019 Paris Tel: 33 1 42 45 09 16 [EMAIL PROTECTED]
