the code in question is a simple but a very handy tool which I use very often on my and other machines of our department. It prints PATH env variable contents line by line, showing '==' signs for repeating paths, and '??' for non-existent ones.

I use for Win32, Linux, SunOS machines quite often with conjuction of other tool, about which I also will tell.

Regards,
Vadim.

#!/usr/bin/perl
my @dirs = split(($^O eq 'MSWin32'?';':':'), $ENV{PATH});
for (0..$#dirs) {
  if (-d $dirs[$_]) {
    print "  ";
  }
  else {
    print "??";
  }
  print (((-d $dirs[$_])?"  ":"??"),(exists $_{$dirs[$_]}?"=":" "),(sp
+rintf "%3d. ",$_+1));
  $_{$dirs[$_]}++;
  print $dirs[$_],"\n";
}
