NAME
ismpx - return windowing terminal state
SYNOPSIS
ismpx [-s]
DESCRIPTION
The ismpx command reports whether its standard input is connected to a multiplexed xt channel; i.e., whether it's running under layers or not. It is useful for shell scripts that download programs to a windowing terminal.
ismpx prints yes and returns 0 if invoked under layers, and prints no and returns 1 otherwise.
-s Do not print anything; just return the proper exit status.
