Re: Read file (cron)

cron is run as the user that created the cronjob.

But lots of things can go wrong here, not the least is the fact that you open a filehandle called TICKS but read the handle with <TICK>. But of course you say that the script actually runs when you test it out so that must not be it.

So beyond that.

Test that you successfully opened the filehandle open(TICK,"textfile") or die("Cannot open file textfile"); or perhaps something more graceful.
Are you sure that the sequence of events which create the file have finished before your cron job starts?
What UID was the cronjob created as? If this is different than the UID which you are using to test the script then things won't be the same.
Do you use certain modules here that are included with your PERL5LIB or other methods - these ENV variables won't be set unless you add some code in your BEGIN block or play around with global environment variables for the shell.
Are you absolutely sure that your cronjob is running - have you debugged your script by having it open and print to a logfile?

Sorry, that was a typo. It should be TICKS throughout. The sequence of events that generate the file are definetly finished before my cron job starts. How do I find out what UID the cron job was created versus what UID the script is run as? I'm positive that my cron job is running. I have it print out messages at different points in the program and i can view these in the /var/spool/mail files.	[reply]
