Re: print() on closed filehandle

You don't check the status of open()ing OUTPUT_FILE. Change your open to read something like:

open (OUTPUT_FILE, ">", $outputfile)
  or die "Unable to open $outputfile: $!\n";

I've also used the 3-argument form of open().

Does the output file have to exist before it the system call on this code is made? Can it not create the file on the fly?	[reply]

It can fail for numerous reasons. The most common are probably: Insufficient permissions Path doesn't exist Disk error (someone ejected it) Invalid characters in file name	[reply]

I am referring to a file that is on another drive, a shared network drive. But I have done this with the input file that is used in the same system call. The file name is fine and so is the directory path. The permissions on the directory are fine.	[reply]

Re^3: print() on closed filehandle by davis (Vicar) on Dec 14, 2004 at 15:57 UTC
The correct answer is: "Try it, or read `perldoc -f open`". The short answer is that using ">" in your open will (attempt to) open the file, clobbering (ie removing) its contents, or creating the file anew if necessary.

But my question really regards the system called statement.	[reply]
