Ksh: Send a mail in case grep finds something
I want to search a file if it contains special strings and if yes, the records found should be mailed.

I can either do it with a temporary file:

Code:
/usr/bin/grep somestring somefile > /tmp/tempfile && /usr/bin/mail -s "Found something" email@mycomp.com < /tmp/tempfile

... or by running the grep command twice:

Code:
/usr/bin/grep -q somestring somefile && /usr/bin/grep somestring somefile | /usr/bin/mail -s "Found something" email@mycomp.com

I wonder if there is another short and smart way doing this without using a file and without using grep twice and without do-loops?

This should run with AIX 6.1, preferably under ksh version 88.

try
Code:
grep somestring somefile | mailx -s "Found something" email@mycomp.com

Thanks, but unfortunately that sends an empty mail in case grep doesn't find anything.

No mail in that case.
Only in the rare case that something is found, the addresse should be notified.

try
Code:
if [ `grep somestring somefile | wc -l` -gt 0 ];
then
grep somestring somefile | mailx -s "Found something" email@mycomp.com
fi

That is what I already had. Please re-read my original post for what I am looking for.
