This worked for me at the command line:

	$ alias rplc="perl -pi -e 's/\r\n?/\n/g'"

Once the alias was created, this is how /bin/bash stored it:

	$ alias
	alias rplc='perl -pi -e '\''s/\r\n?/\n/g'\'''

However, you can use the rules of quoting to create an alias that is
easier to type and easier to read:

	$ alias rplc='perl -pi -e "s/\r\n?/\n/g"'
