good spotted an thanks Lotus1 was just partially my fault: the code was correct but, as i work on an unfriendly OS, i need to put double quotes around the argument. So the actual command line became: `perl -MYAPE::Regex::Explain -e " print YAPE::Regex::Explain->new(qr/$A +RGV[0]/)->explain();" "^\s[^\s\=]+\s="` [download] with the right output: Read more... (2 kB) and the second one `perl -MYAPE::Regex::Explain -e " print YAPE::Regex::Explain->new(qr/$ARGV[0]/)->explain();" "^\s\w+\s="` with his right output: Read more... (2 kB) For the OP the best was probably to highlight only the different part: perl -MYAPE::Regex::Explain -e " print YAPE::Regex::Explain->new(qr/$A +RGV[0]/)->explain();" "[^\s\=]" .. ---------------------------------------------------------------------- [^\s\=] any character except: whitespace (\n, \r, \t, \f, and " "), '\', '=' ---------------------------------------------------------------------- perl -MYAPE::Regex::Explain -e " print YAPE::Regex::Explain->new(qr/$A +RGV[0]/)->explain();" "\w" .. ---------------------------------------------------------------------- \w word characters (a-z, A-Z, 0-9, _) ---------------------------------------------------------------------- [download] L* There are no rules, there are no thumbs.. Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.	[reply] [d/l] [select]
