in reply to Zeroing A File

Update: (added a little more code)

You might consider:

use strict; my $file = '/tmp/this_file'; my $fh; unless (open($fh,">$file")) { die "I can't open $file for writing: $!"; } truncate $fh, 0; close($fh);

Of course, this example is a little contrived, since if you open the file for writing like that and then close it, I think it will truncate it without needing the truncate command. But I can conceive of using that truncate() command if I had been writing to a file and then decided to start over. I must admit, I have never used it.

Another update: Ah, as pointed out by bluto, the truncate command also can be called in the form:

truncate $myfile, 0;

... which is at least somewhat more useful.

If the file is not owned by you, then you may need to have group- or world- writable permissions set on it, depending on your operating system.
