A question on sed:
	I want to replace a string xyz:KJSDKJSDJS: by xyz:: in a
password file. The string "KJSDKJSDJS" is arbitrary. So I try:
	sed -e 's/xyz:\??:/xyz::' $passwd
I guess the regular expression \?? should match any string, but does
not work. I know I am goofing somewhere. Any hints? Thanks.
