You must have set +stdin to be a +.B /dev/tty +device. +.PP +When +.B 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. +.SH RATIONALE +Sometimes you need to be able to know which +console is in the foreground, and stay up to +date on this. In particular, I want to be able +to record the output on the mintors, and have +it detect VT switches, so it can select the +appropriate method and display; and I want to +be able to have VT dependent colour adjustments. +.SH SEE ALSO +.BR fgconsole (1), +.BR chvt (1) +.SH AUTHORS +Principal author, Mattias Andrée.
