Try doing a simple 'cat /var/log/maillog | grep -c check_relay'
You can avoid the unnecessary 'cat' by just passing the filename to
grep directly:
# grep -c check_relay /var/log/maillog
This *should* be quicker, especially in looping constructs.
For my server:
cat /var/log/maillog | grep checK_relay | grep -c spamhaus
836
Again:
# grep -c 'checK_relay.*spamhaus' /var/log/maillog
# grep -c 'checK_relay.*spamcop' /var/log/maillog
# grep -c 'checK_relay.*njabl' /var/log/maillog
Would probably be more efficient and faster, you can test with 'time'
to verify this. You're spawning one process 'grep', instead of three
seperate processes, 'cat, 'grep' and 'grep' again.
It might be quicker, but that doesn't make it more efficient;-)
I often "evolve" my commandlines (I commonly use one that's 500+
characters long) and if I don't start with a cat I often wish I did:-/
