I have a directory in the production environment from which i have to delete files older then 40 minutes with .pid extention. I wrote a script below for the purpose.
Code:
#!/bin/bash
#
# Script to delete specific file older than N minutes.
# OLDERTHAN="40" #40 minutes
FOLDER="home/optima/pids/"
PID="*.pid"
OLDERTHAN="40"
if [ -e ${FOLDER}/${PID} ]
then
ls_time=`ls -l ${FOLDER}/$PID`
pid_h=`echo $ls_time | cut -d\ -f 8 | cut -d\: -f 1`
pid_m=`echo $ls_time | cut -d\ -f 8 | cut -d\: -f 2`
echo pid time=$pid_h:$pid_m
let pid_time=(10#$pid_h*60)+10#$pid_m
curr_h=`date | cut -d\ -f 4 | cut -d\: -f 1`
curr_m=`date | cut -d\ -f 4 | cut -d\: -f 2`
let curr_time=(10#$curr_h*60)+10#$curr_m
echo curr_time=`date | cut -d\ -f 4`
let diff=10#$curr_time-10#$pid_time
#echo pid_time=$pid_time
#echo curr_time=$curr_time
echo diff=$diff minutes
if [ $diff -ge $OLDERTHAN ]
then
echo "${PID} is older than $OLDERTHAN minutes"
echo "Deleting ${PID}..."
rm -f ${FOLDER}/${PID}
else
echo -e "${PID} is not older than $OLDERTHAN minutes"
fi
else
echo -e "${PID} not found."
fi
I created a test pid in /home/somefolder/pids to check if the script will delete old pids or not. I ran it & it showed the following result “*.pid not found.” Any advice?

I replaced PID=”*.pid” with PID="*pid* *.pid*" and ran the script and got the below result. Kindly advice.
Code:
# ./pid_cleanup.sh
./pid_cleanup.sh: script: not found.
./pid_cleanup.sh[10]: Syntax error at line 16 : `(' is not expected.

Please use code tags also in updates. Also please refrain from overly use of font formatting since it is awful to remove when editing your post, thanks. It would be also helpful if you'd use indention when posting your scripts as well.
