Hi.

Good to see people picking up perl. Although use has declined, I still find it very useful. The O'Reilly trilogy is quite useful, and I have found the PBP to be especially valuable. The tools I use the most are align and perltidy. We get many non-standard codes and libraries from The Comprehensive Perl Archive Network - www.cpan.org as well as The world’s leading software development platform . GitHub

Of the 1000+ scripts we have almost 300 are in perl:
Code:
       44 awk-[gmn]awk-native
( ... )
      280 perl
( ... )
      176 sh
     1182 total

For example, to trim things:
Code:
clenfi CLip ENds from FIle, n,m or --top=n --bottom=m; trim, omit.
pll    Print long-line, section, trim, shorten to width as necessary.
trim   Remove strings of whitespace at beginning and end of lines.

In looking at graphs, I get visually confused by too much ink. Going by Tufte https://www.amazon.com/Visual-Displa...dp/0961392142/ and Vellemanhttps://www.amazon.com/Applications-.../dp/087150409X I tend toward less is more, as below.

Keep up the good work ... cheers, drl
