i am generating the above out put for my backup jobs. Now i am checking manually for the validity of the bakup by comparing the times.

Now i am planning to write a shell script to check. first i need to check the todays date and time when the job has started for each and every line.
could any one help me in this how to write a shell script for this. I am a very beginner fot shell scripting.

Thanks in advance,
Raju

Not sure how you want to "check" the data to make sure it is okay. So if you read everyline in the file and compare to todays date then what do you want to do?

For example:
testdate=`date +%m/%d/%Y`
grep "$testdate" $youroutputfile

will give you all lines with the current date where youroutputfile is the name of the file you created by your output. But what do you want to do with the output from the grep command?

Hi Thanks for the reply.
