Not a bug. Reread 'uniq --help', in particular, the bit about: | Discard all but one of successive identical lines from INPUT (or | standard input), writing to OUTPUT (or standard output). If your file is not sorted beforehand, then uniq is not going to sort it either. You may be interested in 'sort -u'. As an aside, I'm wondering if the --help output for uniq should be a bit more explicit about this property; contrast it with the output for join, which states: |Important: FILE1 and FILE2 must be sorted on the join fields. |E.g., use `sort -k 1b,1' if `join' has no options. - -- Don't work too hard, make some time for fun as well!
