Hmm, I never thought that I would learn something about scripting by using COPS
I copied and installed your script into a debian/apache setup.
Out of the box it did not work so I "debugged" a bit.
Herewith my preliminary findings:
0 - I changed other_vhosts_access.log to access.log
1 - Using the line grep -e "200 2183" -e "200 2328" $LOGFILE > cops-log.txt didn't work for me.
a - neither 2183 nor 2328 showed up in my log file. But this was easily fixed with other (for me) matching numbers.
b - Logging into COPS with OPDS gave other numbers than logging into COPS from a browser. Did you take this into account in your script?
c - are you sure that one of these numbers isn't our old friend getJSON and double login log entries?
2 - Writing to TMPFILE did not get the desired result. I "blame" this on:
a - using another log file with a slightly different layout
b - Debian vs Mint date/time formatting (maybe?)
However even this was fixable with a lithe googling. Hey, I even learned something today!
How is the output to look like in your case? Just so I can compare.
3 - I did not (yet) use the mail functionality.
