physlock - lock all consoles / virtual terminals

       Bert Muennich <ber.t at gmx.com>

       physlock  is an alternative to vlock, it is equivalent to `vlock -an'. It is written because vlock blocks
       some linux kernel mechanisms like hibernate and  suspend  and  can  therefore  only  be  used  with  some
       limitations.

       physlock is designed to be lightweight, but highly depends on the kernels ioctl API.

       The  behaviour  of  physlock  is  completely  controlled  via command-line arguments, it does not rely on
       environment variables.  physlock uses the utmp file to identify the owner of the  current  session  (i.e.
       active tty) and prompts for her password to unlock the computer.

-d     Fork  and  detach  physlock  before prompting for authentication. The parent process returns right
              after everything is set up, so this option is useful for use in suspend/hibernate scripts.

       -h     Print brief usage information to standard output and exit.

       -l     Only lock console switching and exit.

       -L     Only enable (unlock) console switching and exit. This is useful when a prior instance of  physlock
              has crashed and leaved the console switching mechanism locked.

       -m     Mute kernel messages on console while physlock is running.

       -pMSG Display MSG before the password prompt.

       -s     Disable SysRq mechanism while physlock is running.

       -v     Print version information to standard output and exit.
