Don't know what you use sort for Mike but it is critial to server
monitoring tools that parse system logfiles.
If it's so critical, why are you just learning about it now? Anyway, for
myself, I keep my logs in ISO date format, which is much easier to parse
for this sort of purpose (YYYY-mm-ddTHH:MM:SS) and works without
specifying any funky options for sort. If you're stuck with logs in
traditional syslog format, try this:
sort -u -k 1,1M -k 2,2n -k 3
Note that the documentation for -M says "month sort"; it says nothing
about days, and certainly doesn't say "by_date". You need something like
the above to specify how you want each column of data sorted. (Initial
column by month, second column numerically, rest in dictionary order.)
Looking at the documentation for sort, it could definately use some
examples like the above to show people how the -M option could be used.
I have no interest in "causing the bug to get more attention" and do
not appreciate the accusation.
It wasn't an accusation, it was a statement of fact. I was also the only
reason I could think of why a problem with a relatively uncommon option
to a non-critical text processing utility would be called "important".
