Re: perl pattern match for end of string using STDIN and chomp

Running the first example code you posted and entering your string does not yield your posted output; rather, it yields the correct output from your second code sample. Have you tested your posted code as written?

#!/usr/bin/perl
print "get some string: ";
chomp($string = <STDIN>);
#$string = $ARGV[0];
#chomp($string);

$string =~ m/\/([[:alnum:]]+)_.*\.(.+)$/;
print "$1\n";
$type = $2;
print "$type\n";

$string =~ m/(.+)\.${type}$/;
#$string =~ m/(.+)\.${type}\Z/;
#$string =~ m/(.+)\.${type}\z/;
#$string =~ m/(.+)\.${type}/;

print "$1\n";

exit 0;

perl 5.8.0 run on Linux 2.4.21-40.ELsmp DOES NOT WORK, you are correct I ran on perl 5.8.7 on my windows machine and it worked fine, going to try and find a more current version on our Linux machine and try and find if it is a perl version problem or if it is directly related to linux	[reply]

Ditto on ikegami above, tested v5.8.8 built for x86_64-linux-gnu-thread-multi on Ubuntu 8.04 LTS as well as Windows. What happens when you run this? `#!/usr/bin/perl print "get some string: "; $dropped = chop($string = <STDIN>); print ord $dropped, " ", ord $/, "\n"; #$string = $ARGV[0]; #chomp($string); $string =~ m/\/([[:alnum:]]+)_.*\.(.+)$/; print "$1\n"; $type = $2; print "$type\n"; $string =~ m/(.+)\.${type}$/; #$string =~ m/(.+)\.${type}\Z/; #$string =~ m/(.+)\.${type}\z/; #$string =~ m/(.+)\.${type}/; print "$1\n"; exit 0;` [download]	[reply] [d/l]

Works for me in 5.8.0 `get some string: /xxxx/yyyy/ZZZ_xxxx.CCC ZZZ CCC /xxxx/yyyy/ZZZ_xxxx` [download] And there's no reason it shouldn't. `$` not matching the end of the string would have been caught by tests. Your build is very broken if the last pattern doesn't match given the specified input.	[reply] [d/l] [select]
