umssync - Synchronise Umsdos directory structure with MsDOS
SYNOPSIS
umssync [
options ]
directory path ...
DESCRIPTION
umssync scan the given directories and compare the content of the
file with the content of the DOS directory. Missing files in
the
are added.
It is expected that this utility will be one day merged into a fsck.umsdos.
This utility is needed because files may be created during DOS session
without LINUX knowing about it. There is no easy way to do this
synchronisation at run time, in the file system driver. The performance
penality would be to high.
need not to run on the entire file system. Only on parts of it
which are activly used (file creation deletion etc...) during DOS session.
is normally run by root. In fact most IOCTL used by
need root effective id.
may be run by a ordinary user.
may be setuid root. If it is run by another user than root, it changes
its behavior. Most options are desallowed and the inheriting mode
is forced on. This means that a user may apply
in any directories, but the files "umssynced" will be given to the
owner of the directory with fairly restrictive permission.
This program has a different set of options if called with the name
umssetup resp.
udosctl. Please try calling the program without an option to get a list.
OPTIONS
All options require an argument. The argument may be glue to the
option letter, or given separatly. Numeric arguments may be given
in decimal, hexadecimal or octal unless specified.
follow C language convention.
Numbers starting with a 0 are octal. Numbers starting with 0x are
hexadecimal.
-c+ or -c-
Sets the conditionnal mode. The default is -c-. Under conditionnal
mode, if a directory do not contain a
file (was never umssync'ed), it won't be touch, nor any of its
subdirectories. This option allows you to apply
to a complete disk without trouble.
-d
Sets the mode value used for
directory entry creation.
The value is numeric only. The value must be an octal number.
See chmod for more info on this. The default
value is 0755 (rwxr-xr-x).
-f
Sets the mode value used for
file entry creation.
The value is numeric only. The value must be an octal number.
See chmod for more info on this. The default
value is 0644 (rw-r--r--).
-g
Sets the group id used for entry creation. The argument may be numeric
or a group name taken from /etc/group.
-i
Sets the inheriting mode. The group and user used for entry creation
are taken from the directory in which they belong.
-i- disable the option.
-i+ enable it.
-r
Control the depth (sub-directory) at which
stops. A value of 0 limits the work to the current directory. The default
value is 0. A value of 99 should be enough to cover the entire file
system.
won't cross file system (partition).
-R
Enables recursion through N directories without a
file, (ie. directories that have not been umssync'ed). For use with the
-c+ and
-r options. The default is 0, (
should not enter these directories).
-u
Sets the user id used for entry creation. The argument may be numeric
or a user name taken from /etc/passwd.
