Not tested, but you should be able to do all that with a single pipeline
to avoid those temporary files:
while true
do
grep "incomplete transaction" /var/spool/exim/log/mainlog | \
egrep -o "<.*>" | sed "s/[<>]//g" | nl | \
sort -u -t @ -k 2 | \
sort -n -k 1 | \
tail -n 250
sleep 15
done
If that doesn't work, you really should use tempfile to avoid
overwriting things in the current directory accidentally.
