I use the command line because later on, I am going to port exercises from the O'Reilly book Data Science at the Command Line to
Perl. This nonsensical idea that Perl is unsuited for "data science" tasks (which is really data cleaning/munging) needs to be
Data Science at the Command Line link
I think this ability to do quick things at the command line is an advantage that Perl has over Python.
You do bring up a good point about the quoting. How should I make this more general, to make clear these one-liners work (with some modification)
on all systems that have Perl and PDL installed?
