A very simple Perl-Script that prints some information about the current string, like length numbers and words:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
#!/usr/bin/perl use strict; print str_stat("123 abc"); sub str_stat { my $var = shift; my $out .= "length = ".length($var); my @text = ("a-zA-Z","words","0-9","numbers"); my @reg = ('[a-zA-Z]','\w+','[1-9]','\d+'); for(0..$#text){ $out .="\n".$text[$_]." = "; $out .=()= $var =~ /$reg[$_]/g; } return($out.$/); } |
Our result:
|
1 2 3 4 5 |
length = 7 a-zA-Z = 3 words = 2 0-9 = 3 numbers = 1 |
