NEWFS(8)                COMMAND REFERENCE                NEWFS(8)



NAME
     newfs - construct a new file system

SYNOPSIS
     /etc/newfs [ -v ] [ -F ] [ mkfs-options ] special

DESCRIPTION
     Newfs is a ``friendly'' front-end to the mkfs(8) program.
     Newfs will use the argument special to obtain information
     about the disk for calculating the appropriate parameters to
     use in calling mkfs, then build the file system by forking
     mkfs.

     Special is the special file (device) on which the file
     system is to be mounted.

     Newfs must be run as super-user, since it must write to the
     file system.

OPTIONS
     -v  Newfs will print out its actions, including the
         parameters passed to mkfs.

     -F  Newfs will only print warnings, rather than exit, if it
         fails to identify the system, or if it discovers the
         special file is a swap device.

     Mkfs-options which may be used to override default
     parameters passed to mkfs are:

     -b block-size
         The block size of the file system in bytes.

     -c #cylinders/group
         The number of cylinders per cylinder group in a file
         system.  The default value used is 16.

     -f frag-size
         The fragment size of the file system in bytes.

     -i bytes/inode
         This specifies the density of inodes in the file system.
         The default is to create an inode for each 2048 bytes of
         data space.  If fewer inodes are desired, a larger
         number should be used; to create more inodes a smaller
         number should be given.

     -m freespace%
         The percentage of space reserved from normal users; the
         minimum free space threshhold.  The default value used
         is 10%.

     -r revolutions/minute
         The speed of the disk in revolutions per minute
         (normally 3600).

     -S sector-size
         The size of a sector in bytes (almost never anything but
         512).

     -s size
         The size of the file system in sectors.

     -t #tracks/cylinder
         The number of tracks per cylinder.

FILES
     /etc/mkfs                to actually build the file system

     /usr/mdec                for boot-strapping programs

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [NP_ERR]       An error occurred that was not a system
                    error.  Execution terminated.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.
