How can I read lines from the end of file in Perl?

Question

I am working on a Perl script to read CSV file and do some calculations. CSV file has only two columns, something like below.

One Two
1.00 44.000
3.00 55.000         


        

Answer 1

The modules are the way to go. However, sometimes you may be writing a piece of code that you want to run on a variety of machines that may be missing the more obscure CPAN modules. In that case why not just 'tail' and dump the output to a temp file from within Perl?

#!/usr/bin/perl

`tail --lines=1000 /path/myfile.txt > tempfile.txt`

You then have something that isn't dependent on a CPAN module if installing one may present an issue.
