NAME
vtchs - Listen for VT switches
ETYMOLOGY
(v)irtual (t)erminal (ch)ange(s)
SYNOPSIS
vtchs
DESCRIPTION
vtchs ignores all arguments. You must have set
stdin to be a /dev/tty device.
When vtchs starts, it prints the number of the
currently active console. Then, in an infinite
loop, it waits for the user to change console,
and prints the number of the newly active console
when this happens.
RATIONALE
Sometimes you need to be able to know which
console is in the foreground, and stay up to
date on this.
