VCRTTY(1) General Commands Manual VCRTTY(1) NAME vcrtty -- try to find a terminal-like name for the current session SYNOPSIS vcrtty DESCRIPTION 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 outputs 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 in- voking 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: vcrtty SEE ALSO tty(1), vcr(1), wmctrl(1) HISTORY The vcrtty utility was written by Peter Pentchev in 2011.
