How many spaces to a tab on this tty

Question

I have a perl script that is writing to stdout which is a tty. Is there a way to determine how many spaces to a tab on that tty?

Generally the "standard" is 8 – Cfreak Nov 12 '10 at 15:34 — Cfreak, Nov 12 '10 at 15:34

8

You want the 'it' capability from terminfo.

use Term::Terminfo;
my $ti = Term::Terminfo->new; 
$tabsize = $ti->getnum( "it" );

What does the "it"-argument mean? – sid_com Nov 12 '10 at 16:08
@sid_com - init_tabs. Google's your friend. One of the first 3 links on googling "terminfo it tab" yields: "it# - Initial number of spaces between tabs."; http://www.comptechdoc.org/os/linux/howlinuxworks/linux_hltermcommands.html – DVK Nov 12 '10 at 17:16
