I just wish to clarify something here. What I am doing is attempting
to reuse a one-liner that has one conditional in it. I do not
consider that to be scripting or programming. I am just piping a few
tools together and checking if anything comes out the end.
I have written bash scripts of course, but those things tend to look
like this:
#!/usr/bin/env bash
SCRIPT_NAME=$(basename $0)
VERSION=1.01.001
AUTHOR="<James B. Byrne>byrnejb@harte-lyne.ca"
DATE_CREATED="2011-Jun-03"
DATE_UPDATED="2011-Jun-03"
# Maximum number of arguments allowed by this program
MAXARGS=99
# Minimum number of arguments required by this program
MINARGS=0
SCRIPT_PATH=$(dirname $0)
usage()
{
cat >&2 << EOD
Version: $VERSION
Usage: $SCRIPT_NAME [options] [arguments]
# Purpose of script:
# This is a script template with examples of getopts usage
#
This script supports the following options:
OPTIONS:
-h Show this message and exit with failure status 2
-a=value set option a to value
-b=value set option b to value
-d=level set debug level to level
. . .
Today when I script then I tend to use Ruby. Tomorrow? Who knows?
