VCRTTY(1) BSD General Commands Manual VCRTTY(1)NAMEvcrtty — try to find a terminal-like name for the current session
SYNOPSISvcrttyDESCRIPTION
The vcrtty utility examines the current session and tries to find the
name of a terminal or something similar that could describe it for tools
like vcr(1) that do different things on different terminals. The vcrtty
utility tries the following in succession:
* If the TTY environment variable is set, vcrtty outputs its con‐
tents.
* If the tty(1) command may be executed successfully, vcrtty out‐
puts its result.
* If the DISPLAY environment variable is set, vcrtty assumes that
this is a X session and outputs a “xdesktopN” string after trying
to determine which X desktop it is running on; for this purpose,
the wmctrl(1) tool is used if available.
* Otherwise vcrtty does not output anything at all; it is up to the
invoking program to decide whether to treat this as an error.
RETURN VALUES
The vcrtty utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
The vcrtty utility examines the TTY and DISPLAY environment variables as
outlined above. Also, the PATH variable may affect its operation when
invoking tty(1) or wmctrl(1).
FILES
The vcrtty utility's operation is not directly affected by any files.
EXAMPLES
Well, just do it - output a usable TTY name:
