I had Cygwin on my office computer for many years, and wrote
shell scripts to do things like reconcile fund lists from
separate source files, and generate reports of the differences.

Here's the top-level script. Both files have to be preprocessed
before comparing them.

#!/bin/sh
awk -f step1.awk -v arg=$1.spec $1 | sort | awk -f step2.awk > t1.out
awk -f step1.awk -v arg=$2.spec $2 | sort | awk -f step2.awk > t2.out
./recon.pl

I'm bad at shell scripts, obviously (step1? step2? Why doesn't
recon.pl use the command line arguments?). I used several
programs together that I knew only how to read the docs for.
Honestly, my first Python scripts from those days aren't that
much better, and have nearly all been themselves abandoned.

Today I'm much more productive with Python. Virtually all my
programs are data conversion and comparisons, with a good deal of
archiving and batch processing of large groups of files. I can
imagine a programmer who is learned in sh, sed, awk, sort and
sundry who would do just fine at these tasks, but I can't imagine
myself going back.
