NAME

       physlock - lock all consoles / virtual terminals

SYNOPSIS

       physlock [-dhLlsv] [-u USER]

DESCRIPTION

       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.  It always allows unlocking as root and as a specified user.  If  no  username  is
       given on the command line, then physlock uses the name of the calling user.

OPTIONS

       -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.

       -s     Disable SysRq mechanism while physlock is running.

       -u USER
              Allow  the  given  user to unlock the computer. Using this option prevents physlock from using the
              name of the calling user.

       -v     Print version information to standard output and exit.
