.TH dpkg\-statoverride 1 "2013-04-01" "Debian project" "dpkg utilities"
.SH NAME
dpkg\-statoverride \- override ownership and mode of files
.
.SH SYNOPSIS
.B dpkg\-statoverride
.RI [ option "...] " command
.
.SH DESCRIPTION
\(lq\fBstat overrides\fR\(rq are a way to tell
.BR dpkg (1)
to use a different owner
or mode for a path when a package is installed (this applies to any
filesystem object that
.B dpkg
handles, including directories, devices, etc.). This can be used to
force programs that are normally setuid to be install without a setuid
flag, or only executable by a certain group.
.P
\fBdpkg\-statoverride\fR is a utility to manage the list of stat
overrides. It has three basic functions: adding, removing and listing
overrides.
.
.SH COMMANDS
.TP
.BI \-\-add " user group mode path"
Add an override for \fIpath\fP. \fIpath\fP does not need to exist
when this command is used; the override will be stored and used later.
Users and groups can be specified by their name (for example \fBroot\fR
or \fBnobody\fR), or by their number by prepending the number with a
\(oq\fB#\fR\(cq (for example \fB#0\fR or \fB#65534\fR).
The \fImode\fR needs to be specified in octal.

If \fB\-\-update\fP is specified and \fIpath\fP exists, it is immediately
set to the new owner and mode.
.TP
.BI \-\-remove " path"
Remove an override for \fIpath\fP, the status of \fIpath\fP is left
unchanged by this command.
.TP
.BR \-\-list " [\fIglob-pattern\fP]"
List all overrides. If a glob pattern is specified restrict the output
to overrides which match the glob.
.TP
.B \-\-help
Show the usage message and exit.
.TP
.B \-\-version
Show the version and exit.
.
.SH OPTIONS
.TP
.BI \-\-admindir " directory"
Change the \fIdirectory\fP of the \fBdpkg\fP database where the statoverride
file is also stored. Defaults to \fI/var/lib/dpkg\fP.
.TP
.B \-\-force
Force an action, even if a sanity check would otherwise prohibit it.
This is necessary to override an existing override.
.TP
.B \-\-update
Immediately try to change the \fIpath\fP to the new owner and mode if it
exists.
.TP
.B \-\-quiet
Be less verbose about what we do.
.
.SH EXIT STATUS
.TP
.B 0
The requested action was successfully performed.
.TP
.B 1
For \fB\-\-list\fP, if there are no overrides or none match the supplied
glob.
.TP
.B 2
Fatal or unrecoverable error due to invalid command-line usage, or
interactions with the system, such as accesses to the database,
memory allocations, etc.
.
.SH ENVIRONMENT
.TP
.B DPKG_ADMINDIR
If set and the \fB\-\-admindir\fP option has not been specified, it will
be used as the \fBdpkg\fP data directory.
.
.SH FILES
.TP
.I /var/lib/dpkg/statoverride
File which contains the current list of stat overrides of the system. It
is located in the \fBdpkg\fP administration directory, along with other files
important to \fBdpkg\fP, such as \fIstatus\fP or \fIavailable\fP.
.br
Note: \fBdpkg\-statoverride\fP preserves the old copy of this file, with
extension \(lq\-old\(rq, before replacing it with the new one.
