beginning Perl tricks 

I've been around in the UNIX world long before Perl made it on the
scene. However, I didn't have time to learn it or use it until well after the release
of 5.0.  I'm just now getting to the point where I'm using Perl as an admin
tool... and I'm amazed.   I wish I'd forced myself to use it earlier...

 example of it's power 

PROBLEM:  I've obtained my own domain.  All of my pages have hard coded references
  	   to my isp.  This isn't really a problem since I have links in place, but
	  it does add to confusion and will ultimately become a maintenance nightmare.

THE FIX NEEDED:   Change all instances of "virtual-cafe" to "wagoneers" and
		all instances of "john" to "john".

SOLUTION:
	perl -pi -e 's/virtual-cafe/wagoneers/g' *.html
	perl -pi -e 's/john/john/g' *.html

 use a simple script to fix the pages 

While I could write a script to loop through my entire website, I'll
simply place this simple script in my script directory (in my path) and
execute it each time I enter a directory that hasn't been updated.  Crude,
but effective.

#!/bin/sh
#   ~/S/FixPages 
#
echo " there were "
grep virtual-cafe *.html | wc -l
echo " occurrences of virtual-cafe, and replaced with wagoneers "
perl -pi -e 's/virtual-cafe/wagoneers/g' *.html

echo " there were "
grep "john"~ *.html | wc -l
echo " occurrences of john, and replaced with john "
perl -pi -e 's/john/john/g' *.html
echo "done with this directory
