Try this: use strict; use warnings; my $tempstr = "abcdefghijklmnopqrstuvwxyz\r\n\r\n\r0123456789\n\n\r"; $tempstr =~ s/(\r?\n)|(\r[^\n])|(\r$)//g; print "[$tempstr]\n"; Output: [abcdefghijklmnopqrstuvwxyz123456789] -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Martin Leese Sent: Friday, November 05, 2004 1:38 PM To: [EMAIL PROTECTED] Subject: How remove newlines?

How remove newlines?
Hi, A nice easy one for a Friday afternoon. I have a variable containing text in which I wish to convert embedded newlines to spaces. And, I wish to do this in a way which is portable. I have come up with: $tempValue =~ s/\r\n/ /g; $tempValue =~ s/\n/ /g; I believe this pair of statements will work on both Windows and UNIX, and with text originating on both Windows and UNIX. I welcome improvements. Also, how do I accommodate Macs? Many thanks, Martin ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
