I am currently running a trigger monitor using 'nohup' command so all the output will be directed to a file. My problem is how to housekeep the outputed file properly. The trigger monitor is running 24hrs a day, 7 days a week.

here's one way to do it - write a cron job that every night does a "tail -500" (or whatever number of lines that takes your fancy) on the output file and redirect it to another file. Then "cat" it back into the original file:

tail -500 out_file > new_file
cat new_file > out_file

Don't forget to capture error output as well as standard output:

runmqtrm > out_file 2>&1 # I can never remember this form!
