How to handle subroutine redefined errors in Perl

So I have a file that in short has this problem...

#!/usr/bin/perl -w
package Foo;

use strict;
use POSIX;

...

sub remove {
  ...
}
...

and I get a get an error saying the subroutine remove has been redefined. I know the problem, there is a subroutine called remove in POSIX. However, I don't know how to handle it. How is this problem typically solved?

Solution

  • do this:

    use POSIX ();

    which will stop the export all default functionality of the POSIX module. You will then need to prefix all POSIX methods with POSIX:: such as:

    POSIX::remove(filename)

    for the POSIX remove function.
