The following reply was made to PR bin/20449; it has been noted by GNATS. From: Gregory Bond <gnb@itga.com.au> To: Cyrille Lefevre <clefevre@citeweb.net> Cc: FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: bin/20449: strange behaviour of sed 's/ */ /' w/ or w/o g Date: Mon, 07 Aug 2000 14:14:26 +1000 > $ echo 'a string with spaces' | sed 's/ */ /' > a string with spaces This is exactly what you've asked for: the first place which matches / */ (i.e. 0 or more spaces, i.e. the empty string at the beginning of the line) is replaced with a space. Similarly with the other 3 examples. Check up the meaning of "*" in regex(3). To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
