Here a way using a script with the following contents...

#!/usr/local/bin/ksh
# 
for fname in $*
	do
		sed "s/\.//" $fname > $fname"x"
		mv $fname"x" $fname
	done
#

...and is executed as follows:
$ <scriptname> <filename expression>

This script will remove "." 's from one or multiple files.
...I think there's a bug in FreeBSD 'sed' implementation ;)
