Writing to files

Basically, the FP below is the file pointer. You open a file using one (>) right angle bracket to overwrite the file with the contents, and two (>>) right angle brackets to append the contents to the file.

The variable $content contains the content you want to add to the file.

You can have as many print commands as you want, as long as they are in between open and close.

open(FP,">filename.txt");
print FP $content;
close(FP);

A better way to write to files

open my $fp, '>', 'filename.txt';
print $fp $content;
close $fp;

Another example

my $content = "write this content to file";
my $filename = 'filename.txt';
open my $fp, '>', $filename or croak "cannot open $filename: $OS_ERROR";
print $fp $content or croak "cannot write to $filename: $OS_ERROR";
close $fp or croak "cannot close $filename: $OS_ERROR";
