Using a newer version of coreutils would tell you why: $ comm test1 test2 1266281 11348282 15431856 16264803 17248121 17384099 18911432 20513956 21436960 21634600 24129206 33773592 37710752 44903491 comm: file 1 is not in sorted order 103652294 103865085 126302054 198494684 208442526 253536357 1002513128 46959037 51274038 comm: file 2 is not in sorted order 103652294 103865085 126302054 208442526 253536357 1002513128 Proper use of comm requires that you pre-sort both input files. As such, this is not a bug in comm, so I'm closing this bug. However, feel free to add further comments or questions. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
