you left off the year...
i'd rather not bloat my 3 line scripts with lookup tables
and recursive date(1) calls, i prefer them easy and short.
here's the full picture of the current situation:
on 1. april i get this file through monthly.local:
logfile-2010-04.log.gz
containing all _march_ entries (plus some april if it creeped in).
i have 2 choices:
1. do the rename dance backwards one month
2. let the job actually run sometimes before midnight, last day of the month.
Not that it helps "unbloating" your scripts, but when I have that
problem I usually cheat by running my script twice - once a few minutes
before midnight (as cron doesn't guarantee execution at a specific time,
only "at or after", we need a margin) and once after.
The first time the script is called (with a switch set to indicate it's
the pre-run) it creates a file containing the current date in a suitable
format. The next time, it uses that file for the rotated log file name.
Here's an example I use to rotate my apache log files. First the crontab
entries:
----8<--------8<--------8<--------8<--------8<--------8<---- (cut)
50 23 * * * /var/www/logs/archivelogs -d
1 0 * * * /var/www/logs/archivelogs
----8<--------8<--------8<--------8<--------8<--------8<---- (cut)
Then the script itself:
----8<--------8<--------8<--------8<--------8<--------8<---- (cut)
#!/bin/sh
cd /var/www/logs
if [ ! -f "./archivedate" ]
then
if [ "$1" = "-d" ]
then
date '+%y%m%d' >./archivedate
exit 0
fi
echo "$0: error: no /var/www/logs/archivedate"
exit 1
fi
ARCHDATE=`cat ./archivedate`
# Make archive directory if it doesn't exist already
mkdir -p ./Archive
if [ -f "./Archive/access-$ARCHDATE.log" -o -f \
"./Archive/access-$ARCHDATE.log.gz" ]
then
echo "$0: error: access.log archive file for $ARCHDATE already
there"
exit 2
fi
if [ -f "./Archive/error-$ARCHDATE.log" -o -f \
"./Archive/error-$ARCHDATE.log.gz" ]
then
echo "$0: error: error.log archive file for $ARCHDATE already
there"
exit 3
fi
mv ./access.log ./Archive/access-$ARCHDATE.log
mv ./error.log ./Archive/error-$ARCHDATE.log
# Hopefully there is a better way to do this...
#/usr/sbin/apachectl stop
#sleep 5
#/usr/bin/nice -8 /usr/sbin/httpd -u
apachectl graceful
sleep 180
gzip -q ./Archive/access-$ARCHDATE.log
gzip -q ./Archive/error-$ARCHDATE.log
rm -f "./archivedate"
exit 0
----8<--------8<--------8<--------8<--------8<--------8<---- (cut)
