       is done by using the carriage return character.  The code in 4.3BSD
       "getty" to do this has never worked right.  This program can function
       as a replacement for "getty".
       Contributor: Gregg Townsend <[email protected]>
   BACKUP-DISK.TAR-Z
       A program to do disk-to-disk backups of file systems or simple

       Contributor: Dwayne Bruce <[email protected]>
   COBWEBS.TAR-Z
       Check for old or unusually large mailboxes.
       Contributor: Don Gworek <[email protected]>
   COPS.TAR-Z
       A large package of system security check programs, including checks
       for world readable/writable devices, world-writable files, "easy"
       passwords, bad .rhosts files, changes in setuid status, and more.
   CORENOTICE.TAR-Z
       Script to find old "core" files and notify their owners.
       Contributor: Anonymous
   CPUTT.TAR-Z

       Contributor: Paul Vixie <[email protected]>
   DBGREP.TAR-Z
       A disk block-based grep-like utility.  This program reads the raw file
       system device and examines all the disk blocks searching for a pattern.
       Regular expressions are not supported, although case may be ignored.
       The names of the files whose disk blocks contain the pattern, along
       with the names of their owners, etc. are printed.  This is faster than
       doing a find/grep combination, since the program does not do all the
       opens, plus it stops searching a file after the first match is found.
       This program works under 4.3BSD and SunOS 3.4.
       Contributor: Dave Curry <[email protected]>
   DUSAGE.TAR-Z
       A program to filter the output of du(1) and produce a report about
       disk space in use, change since last run, etc.
       Contributor: Johan Vromans <[email protected]>
   FINO.TAR-Z
       Find files and inode numbers.  This program reads the raw disk and
       prints out all in-use inodes and their file names.  The real reason
       it exists is to find large files being written but that have been
       unlinked and can't be found with conventional methods.  It's sort
       of a reinvention of what you can do with "icheck" and "ncheck",
       but it's sort of different too.  For 4.xBSD.
       Contributor: Dave Curry <[email protected]>
   FORCE.C
       Another program to allow running a command as the super-user; this
       one requires the password first.
