Perl or Python one-liners

[jasonwalker80]

@ahwagner here is an example of a one liner in the tutorial for evaluating the a GTF format file:

perl -ne 'if ($_ =~ /(gene_id\s\"ENSG\w+\")/){print "$1\n"}' genes_chr22_ERCC92.gtf | sort | uniq | wc -l

The tutorial describes the Perl one-liner usage. Did we decide if we were going to switch out all perl references for python equivalents?

I believe we decided it was not worth reworking these one-liners to Python (not suited). Rather we will overall de-emphasize perl in the course except as a linux tool like any other (grep, awk, sed). But, where there are larger more complex script/programs in perl we might refactor as python.
