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 \-\-force\-help Give help about the \fB\-\-force\-\fP\fIthing\fP options (since dpkg 1.19.5). .TP .B \-\-version Show the version and exit. . .SH OPTIONS .TP .BI \-\-admindir " directory" Set the administrative directory to \fIdirectory\fP. This is where the \fIstatoverride\fP file is stored. Defaults to \(Fo\fI/var/lib/dpkg\fP\(Fc. .TP .BI \-\-instdir " directory" Set the installation directory, which refers to the directory where packages get installed (since dpkg 1.19.2). Defaults to \(Fo\fI/\fP\(Fc. .TP .BI \-\-root " directory" Set the root directory to \fBdirectory\fP, which sets the installation directory to \(Fo\fIdirectory\fP\(Fc and the administrative directory to \(Fo\fIdirectory\fP\fB/var/lib/dpkg\fP\(Fc (since dpkg 1.19.2). .TP .B \-\-force\-\fIthings\fP .TQ .BR \-\-no\-force\-\fIthings\fP ", " \-\-refuse\-\fIthings\fP Force or refuse (\fBno\-force\fP and \fBrefuse\fP mean the same thing) to do some things (since dpkg 1.19.5). \fIthings\fP is a comma separated list of things specified below. \fB\-\-force\-help\fP displays a message describing them. Things marked with (*) are forced by default. \fIWarning: These options are mostly intended to be used by experts only. Using them without fully understanding their effects may break your whole system.\fP \fBall\fP: Turns on (or off) all force options. \fBstatoverride\-add\fP: Overwrite an existing stat override when adding it (since dpkg 1.19.5). \fBstatoverride\-remove\fP: Ignore a missing stat override when removing it (since dpkg 1.19.5). \fBsecurity\-mac\fP(*): Use platform-specific Mandatory Access Controls (MAC) based security when installing files into the filesystem (since dpkg 1.19.5). On Linux systems the implementation uses SELinux. .TP .B \-\-force Force an action, even if a sanity check would otherwise prohibit it. This is necessary to override an existing override. This option is deprecated (since dpkg 1.19.5), it is replaced by \fB\-\-force\-all\fP. .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_ROOT If set and the \fB\-\-instdir\fP or \fB\-\-root\fP options have not been specified, it will be used as the filesystem root directory (since dpkg 1.19.2). .TP .B DPKG_ADMINDIR If set and the \fB\-\-admindir\fP or \fB\-\-root\fP options have not been specified, it will be used as the \fBdpkg\fP data directory. .TP .B DPKG_FORCE If set and none of the \fB\-\-force\-\fP\fI...\fP options have been specified, it will be used as the force options to use (since dpkg 1.19.5). .TP .B DPKG_COLORS Sets the color mode (since dpkg 1.18.5). The currently accepted values are: \fBauto\fP (default), \fBalways\fP and \fBnever\fP. . .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. . .SH SEE ALSO .BR dpkg (1).
