man lockit

NAME

  lockit - lock terminal with password

SYNOPSIS

  lockit [-options]

DESCRIPTION

  The lockit command will lock a terminal trapping common signals.  By
  default the utility will ask for a 'lockword' unless one was  previ-
  ously  saved in ~/.lockit or unless the crypted password is readable
  from /etc/passwd.

OPTIONS

  -password
         Specify the crypted password from /etc/passwd should be  used
         if it is valid.

  -ask    Ask for lockword (standard input).

  -save   Save crypted lockword in ~/.lockit for re-use.

  -crypted crypted-string
         Use the provided crypted string for lockword.

  -zzz seconds
         Specify  number of seconds to sleep before redisplaying time,
         default is 120 seconds.

  -noverify
         By default lockit always asks for verification of  the  lock-
         word,  whether  source  is from -ask, -crypted, or -password.
         With this option verification is not requested.

EXAMPLES

  Default invocation:

   java: lockit
   Lockword:
     Verify:
   1999-10-10 18:14:18
   <ctrl-C>
   Lockword:

  Saving lockword for re-use:

   java: lockit -save
   Lockword:
     Verify:
   lockit: Created /users/sn/snkac/.lockit: z(2227)
   1999-10-10 18:14:49
   <ctrl-Z>
   Lockword:

  Using previously saved lockword without verification:

   java: lockit -noverify
   1999-10-10 18:15:10
   <ctrl-Z>
   Lockword:

  The .lockit file includes a time stamp and a sum byte to ensure  the
  crpyted lockword string is not tampered.

NOTES

  lockit has been tested under Digital UNIX, IRIX, and UNICOS.

  Suggestions  for  enhancements  or  bug  reports  can be directed to
  fnkac@uaf.edu.

  This command utilizes the cci command parser  utilized  by  non-UNIX
  operating  systems instead of the traditional UNIX getopt() parsing.
  Options have been defined to "look like" UNIX style options, but can
  be  spelled  out  or generally abbreviated.  For example '-p' is the
  same as '-password'.  Because of this multiple options must be space
  separated  and  the hyphen is part of the option name.  Also because
  of this order of options is irrelevant.
