How To Write Into Files in Perl

In Perl, you can easily write to files using various file handling functions. Here's a basic example:

```perl

Open a file in write mode

my $filename = 'output.txt'; open(my $fh, '>', $filename) or die "Could not open file '$file_name' $!";

Data to write into the file

my $data = "Hello, this is some content to write to the file!\n";

Write data to the file

print $fh $data;

Close the file

close($fh); ```

Let's break this down:

• open(my $fh, '>', $file_name) opens a file named output.txt in write mode ('>'). It returns a file handle $fh to perform operations on the file.
• print $fh $data writes the content stored in $data to the file associated with the file handle $fh.
• close($fh) closes the file once you're done writing to it.

You can also check for errors when opening the file using die to handle potential issues with file opening.

Remember to handle errors gracefully and close the file handle once you're finished writing to the file. Additionally, you can use other modes like >> to append to a file rather than overwriting it.
