I need some help making this script... I guess I'm having trouble even interpretating what to even get started on...

I need to create a script that will search a given directory (typically a user's home directory, but not necessarily) as provided on the command line and any sub-directors for temp files/directies matching the criteria (which is written below) and delete them.

The only criteria are
Temp file and temp directory names will begin with a comma (,).
Temp files and temp directories (including all of their contents) will be removed 5 days after the last modification date of the file or directory.
The home directory and all of its subdirectories, only users with user ids greater than or equal to 500 will be checked for temp files and directories.

Anyone mind showing a sample script, or point me in the right direction here? I'm stumped...

this will help you to find files whose names begin with comma:

find . -name ',*'

id someuser

Hi Jukai,

Completing Yogesh's relpy....

#! /bin/sh

#Get the list of users in home directory
LIST=`ls -l /home | awk '{print $9}'`

#Find the users who have a user-id greater than 500
for USER in $LIST
do
USER_ID=`/usr/bin/id ${USER} | cut -f1 -d '(' | cut -f2 -d'='`
if [ ${USER_ID} -gt 500 ]
then
SUCC_LIST=`echo "${SUCC_LIST} ${USER}"`
fi
done

#Delete the files which are older than 5 days for the above collected users
for USR in ${SUCC_LIST}
do
/usr/bin/find /home/${USR} -name ",*" -type f -mtime +5 -exec /bin/rm -f {};
done


Note: Remember the above script deletes only files but not directories... for that u can modify the last find command accordingly....
