Shell Programming and Scripting

Hello,

My script has a trailer record(TR).

Now I need to implement a logic, if TR is missed on the file it should generate me an email stating TR was not on the file..

Kindly help.

Please provide an example of your script's trailer record

.... and a sample of other records so that we can clearly identify what is acceptable.

If you simply want to check that the last line starts TR that is easy (when you know how) but if the requirement is more complex it might take some thinking.


Regards,

yes I simply want to check if last line has TR or not..

Currently my file is as below. Hence if last line has TR then no issues but if it do not then it should generate a email to me stating TR was missing on the file

Code:

1|xyz
1|123
2|abc
2|456
TR| total records

Please wrap all code, files, input & output/errors in CODE tags It makes them easier to read and preserves critical multiple spaces, as that can be very important.

Try

Code:

[ $(tail -1 file | cut -d\| -f1) == "TR" ] || echo mail something

I guess this might work too:

Code:

tail -1 file | grep ^TR || echo mail something

Can you guys explain along with if statement, I tried the below

if [ $(tail -1 file | cut -d\| -f1) == "TR" ]
then
echo "Trailer record is missing on the file" | mailx -m -s "Trailer record missing" a_b@x.com
fi

But this isn't working.
