And, if you're curious, the following one line C program will also do the
trick, assuming it IS run from a terminal (/usr/bin/tty is just a more
complex version of this).
#include <stdio.h>
void main()
{
(void)printf("%s\n", ttyname(0));
}
ryan@ren:/home/ryan $> cc -o mytty mytty.c
ryan@ren:/home/ryan $> mytty
/dev/ttyv2
( Recommendation: Just use tty(1)... it's pretty much been around since
day 1.. So I think it qualifies for "cross platform" and
"non-shell-specific" :-)
On some systems, I like to include the terminal in my shell prompts for
interactive logins. In Bourne shells,
export PS1="`tty | cut -c 6-` $USER@....whatever else you like to put in
your prompt"
