I have some ideas, but I thought I'd give you folks a crack at this Big Fun: a) You have a directory of files - say they're logs - generated at nondeterministic intervals. You may get more than one a day, more than one a month, none, or hundreds. b) To conserve space, you want to keep the last file generated in any given month (the archive goes back for an unspecified number of years), and delete all the files generated prior to that last file in that same month. c) Bonus points if the problem is solved generally for either files or directories generated as described above. These are not actually logs, and no, I don't think logrotate can do this ... or can it?here's a one-liner: rm ` \ stat -f "%SB %B %N" * \ | sort -k5nr \ | cut -c1-7,17-20,32- \ | awk 'BEGIN {a="";b=0;c=0} $1==a && $2==b && $3=c {print $4;}{a=$1;b=$2;c=$3}' \ ` This selects on creation date. change the B (both of them) in the stat call to use a different timestamp
Thanks to all that took the time. Interesting responses. It will be fun to cook up my own version. -- ---------------------------------------------------------------------------- Tim Daneliuk tun...@tundraware.com PGP Key: http://www.tundraware.com/PGP/ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
