Create a file

Create a file. Open the file in write mode. Perl doesn't have a function just to create a file. To create the file, use the write mode of open function.

open my $fh, ">", $file;

Example

This is an example to create a file.

use strict;
use warnings;

# Create a file. open my $fh, ">", $file

print "1: Create a file.";
my $file = "example_20080519_ $$. txt"; # $$is the process ID

if (-e $file) {
  die "$file already exists.";
}
else {
  open my $fh, ">", $file
    or die "Unable to open $file in write mode .:$!";
  close $fh;
}
