It looks like that the COLUMNS env variable isn't passed to perl (see the
attached 'columnstest' file), unless it is explicitly set from the shell
(i.e. COLUMNS=$COLUMNS perl ./columnstest).
That's right, COLUMNS is actually a bash variable, and is
not normally part of the environment. You can get it from
the output of resize(1) though:
#! /usr/bin/perl
$columns = (`resize` =~ /COLUMNS=(\d+)/)[0];
print $columns;
I'll let it up to who will maintain that code to write it in
a more palatable way :-)
