As small improvement, you can use $. instead of $cnt, as is documented in perlvar.

Actually, his specific point was that one probably didn't want to count the number of lines read from the file, but instead the number of lines printed. Because of the presence of the `next` statement, they're not the same thing. Thus the use of the `$cnt` variable to keep track of the number of lines printed. perl -pe '"I lo`+$^X$\"$]!$/"=~m%(.)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'	[reply] [d/l] [select]
