Bash Directory Cleaner

There are times when one will have non-rotating log files in one’s code. The scripts keep generating more logs based on the date and the directories keep filling up. What is one supposed to do?

This is a quick Bash directory cleaner I use:

function usage() {
echo "Usage: $0 [d directory] [t time_in_days]"
exit 1
}

TIME=30
HOMEDIR=/home/zenoss
SCRIPTSDIR=${HOMEDIR}/scripts
LOGDIR=${SCRIPTSDIR}/log

REMOVEFILE=${LOGDIR}/findResults.$$.txt

while getopts d:t: flag
do
case "${flag}" in
d) DIRECTORY=${OPTARG};;
t) TIME=${OPTARG};;
[?]) usage;;
esac
done
shift $((OPTIND - 1))

if [ $# -ne 0 ]
then
usage
fi

if [ ! -d "$DIRECTORY" ]
then
echo "Directory specified was not a directory"
exit 2
fi

find ${DIRECTORY} -mtime +${TIME} > ${REMOVEFILE}

echo "Removing: "
cat ${REMOVEFILE}

for each in `cat ${REMOVEFILE}`
do
rm $each -f
done

rm ${REMOVEFILE}

This script allows one to chose a directory and how many days of logs to keep.

Here is an example usage:


0 12 * * 1 /home/user/scripts/bin/dirCleaner.sh -d/home/user/scripts/log -t31 >> /home/user/scripts/log/dirCleaner.`date +\%Y\%m\%d`.log 2>&1
