tty1
Return user's terminal name
Usage
tty [-s]
Overview
The tty utility writes the name of the terminal attached to standard input to standard output. The name that is written is the string returned by ttyname(3). If the standard input is not a terminal, the message “not a tty” is written. The options are as follows:
-
-s -
Do not write the terminal name; only the exit status is affected when this option is specified. The
-soption is deprecated in favor of the “test -t 0” command.
Exit status
The tty utility exits 0 if the standard input is a terminal, 1 if the standard input is not a terminal, and >1 if an error occurs.
