MKPROTO(8)                BSD System Manager's Manual               MKPROTO(8)

NAME
     mkproto - construct a prototype file system

SYNOPSIS
     mkproto special proto

DESCRIPTION
     Mkproto is used to bootstrap a new file system.  First a new file system
     is created using newfs(8).  Mkproto is then used to copy files from the
     old file system into the new file system according to the directions
     found in the prototype file proto. The prototype file contains tokens
     separated by spaces or new lines.  The first tokens comprise the specifi-
     cation for the root directory.  File specifications consist of tokens
     giving the mode, the user-id, the group id, and the initial contents of
     the file.  The syntax of the contents field depends on the mode.

     The mode token for a file is a 6 character string.  The first character
     specifies the type of the file.  (The characters -bcd specify regular,
     block special, character special and directory files respectively.)  The
     second character of the type is either u or `-' to specify set-user-id
     mode or not.  The third is g or `-' for the set-group-id mode.  The rest
     of the mode is a three digit octal number giving the owner, group, and
     other read, write, execute permissions, see chmod(1).

     Two decimal number tokens come after the mode; they specify the user and
     group ID's of the owner of the file.

     If the file is a regular file, the next token is a pathname whence the
     contents and size are copied.

     If the file is a block or character special file, two decimal number to-
     kens follow which give the major and minor device numbers.

     If the file is a directory, mkproto makes the entries `.' and `..' and
     then reads a list of names and (recursively) file specifications for the
     entries in the directory.  The scan is terminated with the token $.

     A sample prototype specification follows:

           d--777 3 1
           usr     d--777 3 1
                   sh      ---755 3 1 /bin/sh
                   ken     d--755 6 1
                           $
                   b0      b--644 3 1 0 0
                   c0      c--644 3 1 0 0
                   $
           $

BUGS
     There should be some way to specify links.

     There should be some way to specify bad blocks.

     Mkproto can only be run on virgin file systems.  It should be possible to
     copy files into existent file systems.

HISTORY
     The mkproto command appeared in 4.2BSD.
