Thanks for the help, guys. Below is a portion of my sed script. It just goes
through a bunch of html files and replaces outdated URLs with the correct
locations. All substitions are the same format.

I think I may have solved my problem. Most of these html files were created on
Macs or Windows PCs. Using tr, I replace the returns w/ a newline and then pipe
it into sed:
tr "[\r]" "[\n]" < ${1} | $sed > ${1}.new 2>/dev/null
The "2>/dev/null" is to get rid of the sed errors about the missing newline on
the last line of the file. This appears to be working with one exception. On
the Macs and most PC editors, the files still appear normally after being
massaged by tr and sed. The exception is Windows notepad - when the the altered
files are opened w/ notepad, they become on long line with some junk characters
appearing in lieu of newlines. Wordpad, Word and Netscape composer don't have
any problems. I figure if anyone uses notepad and complains, I can just tell them
to use a better editor (which would be just about anything else).
Ideally, I would like to return the files to the original condition regarding
newlines and returns, but putting
tr "[\n]" "[\r]"
on the end of the above pipe didn't do it. Any ideas?
