Or even shorter, using split to extract the name of the gene:
use Modern::Perl qw/2015/; use autodie; open my $IN, '<', 'genes.tsv'; open my $OUT, '>', 'genesymbol.txt'; say $OUT ( split "\t" )[1] while (<$IN>);

split "\t" works very well for this very simple TSV file. However, for any even a bit more complicated TSV or CSV file, the use of Text::CSV comes highly recommended!


A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
