Help with a regex

cspctec has asked for the wisdom of the Perl Monks concerning the following question:

I have an array that has the following values:

nfcclib
lib
[download]

and I need to match only "lib", not "nfcclib". I have tried the following regex with no success...

/^lib$/
/^lib/
[download]

I thought the carrot and dollar sign meant the beginning and end of the string, but it matches nfcclib also. Any help is appreciated.

I get the following: `use warnings; use strict; use Data::Dumper; chomp( my @array = <DATA> ); for (@array) { chomp; if (/^lib$/) { print "Yes: $_\n"; } else { print "No : $_\n"; } } print "\n", Dumper \@array; __DATA__ nfcclib lib` [download] Output: `No : nfcclib Yes: lib $VAR1 = [ 'nfcclib', 'lib' ];` [download] Consider using Data::Dumper to examine the array's elements. Hope this helps Edit: Added Data::Dumper.	[reply] [d/l] [select]

You understood ^ and $ correctly, you probably test it wrong. Could you give us the code sample that makes you reach that conclusion ? `perl -E 'say /^lib/ ? "$_ matched" : "$_ did not match" for qw/nfcclib lib/;'` `nfcclib did not match lib matched` [download] Alternatively, you could also use \b which means word boundary (so the regex `m<\blib>;` or its equivalent `/\blib/`)	[reply] [d/l] [select]

show your code, as the carrot and dollar solution should work, perhaps the bug is elsewhere or there are white-spaces in your array values. This is not a Signature...	[reply] [d/l]

you can match it with eq if regexp doesn't work	[reply]
