Hi all, In my script, I have a system call, and redirect the stderr to a file. # # open STDERR, ">$workpath\\error_log.txt"; # system "..."; # but I only want the ERROR messages to be logged in the file. Is there any method to filter the WARNING messages generated by the system call. Thanks.
You're talking about the warnings generated by the program in the system call, not something perl generates, correct?
If so, check the documentation on the program to see if warnings can be suppressed. If not, then what are the criteria that separates the warnings from the errors? Once you know that, you can write a filter to remove them.
