Column handling in Perl

Problem

During my first encounters with Perl many years ago, I asked how can I get a specific column.

It was so easy in AWK!

Use split:
my @columns = split /\t/, $input;
my $third_column = $columns[2];

Problem	Solution	Example	Reference	Recommended
Show column 1: perl -ane 'print $F[0]."\n";' Show column 2: perl -ane 'print $F[1]."\n";' Show last column: perl -ane 'print $F[$#F]."\n";' Show last but one column: perl -ane 'print $F[($#F-1)]."\n";' So you just run your program, or cat your file, etc and pipe it through this code to get specific column.
