Let's say you have a list of error patterns in patterns.txt:

error3
error7

And your logs are in a file called all.log. Then you could generate a temporary file with the errors that match your specified patterns, and if the file is non-empty, then email it to yourself:

grep -f patterns.txt all.log > /tmp/matches.log
test -s /tmp/matches.log || mailx -s 'interesting errors' [email protected] < /tmp/matches.log

You can do it without a temporary file by storing the result of grep in a variable:

matches=$(grep -f patterns.txt all.log)
test "$matches" && echo "$matches" | mailx -s 'interesting errors' [email protected]
