A compromise perhaps bolting several things together.

From the suggestions given and further digging, I've ended up with:-
Code:
awk "/Active transaction started/ && /${userregex}/ {print \$1, \$2, \$3 \$11 \
> \"/tmp/logs/splitlog.\"gensub(/[^[:alnum:]._-]/, \"\", \"g\", \$11)}" /var/log/qapplog

for userfile in /tmp/logs/splitlog.*
do
   lastrecord=$(tail -1 $userfile)
   printf "User %s last record is %s\n" "$userfile" "$lastrecord"
   .... whatever else here ....
done

To explain it a bit more:-
  • The ${userregex} is a regular expression for all the users we are interested in, so we can exclude testing messages which sadly get written to the same log.

  • The text output is just for checking we've got it, there would be further processing (and that's all fine) This is finding a way to get the last logged entry for each user, so the printf line is just for debug.

  • We removed the grep with the two expressions (both must be satisfied) see this thread

  • The output file(s) are redirected to /tmp/logs/splitlog. appended by the output from the gensub on field 11. The gensub removes all characters from field 11 that are not matched by being alphanumeric, full-stop (period for American English), underscore or hyphen, those all being acceptable characters to build a filename from and sensibly allowed in user account names. We could possibly have apostrophes too, but these have been excluded.

It seems to work for me in testing, but I'd appreciate another few sets of eyes to validate I'm not doing something daft and leaving a gaping hole somewhere.
