Hello all. I have tried to do something simple. Do ls, pipe it to perl -ne (using xargs) and print. And it runs indefintely. I have tried something simple, like printing out only the directories. See code below

  ls | xargs perl -ne ' map { print $_ , "\n" if ( -d $_ )  ; } @ARGV  '

This runs almost indefintely. However this gets me what I need:

  ls | xargs perl -ne ' $a = shift ; print $a  "\n" if (-d $a) ;  '

why?

In reply to ls piped tpo perl -pe runs indefintely by ISAI student
