Hi all,

I work in Sun Solaris 9. I am plan to put the following script(remove90dysOldrfiles.sh) in CRONTAB for removing huge huge number of files those are older than 90 days from different directory.
In the Crontab i will set the time for everymidnight it will search 90days older file and remove it from system.

But my confusion is how the Following script will work is it Like- every command for find and remove will execute one after another or parallel processing could be happen. If parallel processing could be occur than i scared CPU usage will be too much higer in system, which will effect the live system offcourse. Experts i need your earnest advise from you.

# vi /var/opt/remove90dysOldrfiles.sh

#!/usr/bin/sh
find /var/opt/backup/backup1 -name "USR*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/backup/backup2 -name "CUST*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/Mainbackup/backup3 -name "SUB*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/backup/backup4 -name "GP*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/Mainbackup/backup5 -name "AIR*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/backup/backup6 -name "IN*" -mtime +90 | xargs -n 100 rm -f
find /var/opt/Mainbackup/backup7 -name "MS*" -mtime +90 | xargs -n 100 rm -f
