You might like Perl's -l command line switch. One of the things it does is setting $\ (the output separator) to a supplied value, or to $/. $/ is \n by default. So if you use perl -le'', newlines are automatically added to prints. Together with the for modifier, you can write your script as:

perl -le'print for @INC'

A little more useful if you have relative paths in your @INC...

perl -MCwd=abs_path -le 'print for map abs_path($_), @INC'

    --k.

perl -MCwd=abs_path -le 'print for map abs_path($_), @INC'
[download]

That's a sortofa useless map in there, if you shuffle a bit:

perl -MCwd=abs_path -le 'print abs_path($_) for @INC'
