Cron tab time generation script
Hi folks,

Everyone knows about crontab, what i am looking for a script where i will define hour,minute and day and it will generate crontab complete time entry, i have seen many website generating crontab entry and my question is that is there any shell script that can do same work.

Code:
20 09 * * 5 command

Hello,
assuming three command line parameters as:
$cronscript.sh <hr> <min> <day>

the script would be:
Code:
HR=$1
MIN=$2
DAY=$3

crontab -l > cron_now
#add new cron into cron file
echo "$MIN $HR * * $DAY script-which-needs-to-be-added-to-cron" >> cron_now
#install the new cron_now file
crontab cron_now
#remove the temp cron_now file
rm cron_now
