Bug Wants to change shell script into crontab
Hi friends,

Actually i wrote many scripts in korn shell for time saving activity in storage domain. But every week i am spending some time for the running of script. So every Monday i wants to run my scripts automatically. So corn will be helpful according to my friend's opinion.
But I don't know how to change my script into corn.
Can anyone help me please?

Below is one of my sample script, can anyone same to corn.

Code:
#! /bin/ksh

if [[ $# < 1 ]];then
   clear

  read sid?"Enter last four digits of the SYMM frame:"

else
   sid=$1
fi

sudo symdev -sid $sid list -noport -nobcv >> /home/gopalpa/no_port1.$sid

cat /home/gopalpa/no_port1.$sid|awk '$1 != "Symmetrix"' >>/home/gopalpa/no_port2.$sid

cat /home/gopalpa/no_port2.$sid|awk '$NF != 3' >>/home/gopalpa/no_port3.$sid

cat /home/gopalpa/no_port3.$sid|awk '{tot+=$NF;print " Dev "$1" Dev size "$NF}END {print "Total capacity of unmapped devices  " tot " MegaBytes"}' >> /home/gopalpa/no_port.$sid

echo "unmaped devices --> cat /home/gopalpa/no_port.xxxx"

echo "Checking capacity of no_port devices in symm $sid.... /n"
cat /home/gopalpa/no_port.$sid| sed '$!d'

rm /home/gopalpa/no_port3.$sid
rm /home/gopalpa/no_port2.$sid

1. Is your script working now as is "without changing to cron"?
2. Crontab contains entries which defines when a command or script should run. Usually this is defined in "/etc/crontab" file.
3. If your script runs as is without any errors, all you have to do is add this line in crontab to run every monday at 9am
Code:
0 9 * * 1    /home/usr/script.sh

Additionally. Cron is a job scheduler in Unix environment helping to run scripts/jobs periodically. There is no need to change the code to run in cron but once you develop your code just add script-name plus time period to the crontab file. Though check here for further explanation. Often used options are
Code:
crontab -l # to lists cron entries
crontab -e # to edit/add cron entries. Use this option with caution

so no nedd to open a the default editor (sudo crontab -e) and pasting the above script in that vi?????


so every monday running this command (0 9 * * 1 /home/usr/script.sh) is enuf? rite?
