Code:

$matchme = "some stuff";
if ( $matchme =~ m/[a-z]/ ) {
   print "Oh snap you matched.";
}

By the number of matches found: 0 -> false, >=1 -> true:

Code:

zsh-4.3.9[sysadmin]% perl -le'print shift=~/OK/?"true":"false"' OK
true
zsh-4.3.9[sysadmin]% perl -le'print shift=~/OK/?"true":"false"' KO
false
