Solaris

I have a shell script with the following Command

/vs/bin/display message priority critical start '09/14 11:00:00' stop '09/15 10:59:59' all >> /unused1/Monitoring/Log/log.txt

Where i want the date part to update automatically by a day,
Please advice.

Execute the following script in cron daily, so it will change that date accordingly.

Code:

tomorrow=`date --date='tomorrow' +%m/%d`
today=`date +%m/%d`
date='[0-9]\+/[0-9]\+'
sed "s#start '$date\(.*stop '\)$date#start '$today\1$tomorrow#" <FILENAME>

Note: If the pattern matches only this line, it will change correctly. If you have some other line also that matches it, then you are in trouble..

1. Give that shell script filename instead of <FILENAME>
2. Once after you tested that above worked correctly, add the -i option to sed command which will edit that file itself.
