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.
