Description
kbdinfo is an interface to KDGETMODE, GKBMODE, GKBMETA and GKBLED ioctls. Its primary use case is to query the status of the given CONSOLE (or the currently active one, if no -C option is present) from a shell script.
If the final value argument is not specified, kbdinfo will print the result of the desired ioctl to the standard output. Otherwise, the given value is compared to the actual result, and the utility will exit with a status code of 0 for a match, 1 otherwise. No text is printed for this style of invocation.
