mkproto(8)mkproto(8)NAMEmkproto - Constructs a prototype file system
SYNOPSISmkproto special proto
DESCRIPTION
The mkproto command is used to bootstrap a new file system. First a new
file system is created using newfs. 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 con‐
tains tokens separated by spaces or newlines. The first tokens comprise
the specification 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 a u or a - (dash) to specify
setuid mode or not. The third character is either a g or a - (dash) for
the setgid mode. The rest of the mode is a 3-digit octal number, giving
the owner, group, and other read, write, execute permissions. (See the
chmod(1) command for more information.)
Two decimal number tokens come after the mode; they specify the user
and group IDs of the owner of the file: If the file is a regular file,
the next token is a pathname from which the contents and size are
copied. If the file is a block-special or a character-special file,
two decimal number tokens follow, giving the major and minor device
numbers. If the file is a directory, mkproto makes the entries . (dot)
and .. (dot dot) and then reads a list of names and (recursively) file
specifications for the entries in the directory. The scan is terminated
with the token $.
The following listing shows a sample prototype specification.
