Hi Johnno-- You can use '+' in a regex to mean 'one-or-more', so s/\|+/|/ would mean "replace one or more pipe with a single pipe" (you don't need to escape the pipe in the replacement string).
As a style matter, you can enclose the pipe in a chacter class with []s to make it easier to read: s/[|]+/|/ So your problem would look like: perl -e '$string = q/1||||2||||3|4|||5/; $string =~ s/[|]+/|/g; print "$string\n"' 1|2|3|4|5 Run perldoc perlre to see an in-depth explaination of all this. --Kester > Hello All, > > I have a string that has got > > 1||||2||||3|4|||5 > > What I need it in is > > 1|2|3|4|5 > > I have tried > > $string =~ s/\||/\|/g; > > and i get this as a result > > |1|||||2|||||3||4||||5| > > what am i doing wrong? > > Mnay Thanks, > > Johnno > _______________________________________________ > Perl-Unix-Users mailing list > [EMAIL PROTECTED] > To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs _______________________________________________ Perl-Unix-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
