.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBsudo\fR accepts the following command line options:
-.IP "\-a" 4
-.IX Item "-a"
-The \fB\-a\fR (\fIauthentication type\fR) option causes \fBsudo\fR to use the
-specified authentication type when validating the user, as allowed
-by \fI/etc/login.conf\fR. The system administrator may specify a list
-of sudo-specific authentication methods by adding an \*(L"auth\-sudo\*(R"
-entry in \fI/etc/login.conf\fR. This option is only available on systems
-that support \s-1BSD\s0 authentication.
-.IP "\-b" 4
+.IP "\-A" 12
+.IX Item "-A"
+Normally, if \fBsudo\fR requires a password, it will read it from the
+current terminal. If the \fB\-A\fR (\fIaskpass\fR) option is specified,
+a (possibly graphical) helper program is executed to read the
+user's password and output the password to the standard output. If
+the \f(CW\*(C`SUDO_ASKPASS\*(C'\fR environment variable is set, it specifies the
+path to the helper program. Otherwise, the value specified by the
+\&\fIaskpass\fR option in \fIsudoers\fR\|(@mansectform@) is used.
+@BAMAN@.IP "\-a \fItype\fR" 12
+@BAMAN@.IX Item "-a type"
+@BAMAN@The \fB\-a\fR (\fIauthentication type\fR) option causes \fBsudo\fR to use the
+@BAMAN@specified authentication type when validating the user, as allowed
+@BAMAN@by \fI/etc/login.conf\fR. The system administrator may specify a list
+@BAMAN@of sudo-specific authentication methods by adding an \*(L"auth-sudo\*(R"
+@BAMAN@entry in \fI/etc/login.conf\fR. This option is only available on systems
+@BAMAN@that support \s-1BSD\s0 authentication.
+.IP "\-b" 12
.IX Item "-b"
The \fB\-b\fR (\fIbackground\fR) option tells \fBsudo\fR to run the given
command in the background. Note that if you use the \fB\-b\fR
option you cannot use shell job control to manipulate the process.
-.IP "\-c" 4
-.IX Item "-c"
-The \fB\-c\fR (\fIclass\fR) option causes \fBsudo\fR to run the specified command
-with resources limited by the specified login class. The \fIclass\fR
-argument can be either a class name as defined in \f(CW\*(C`/etc/login.conf\*(C'\fR,
-or a single '\-' character. Specifying a \fIclass\fR of \f(CW\*(C`\-\*(C'\fR indicates
-that the command should be run restricted by the default login
-capabilities for the user the command is run as. If the \fIclass\fR
-argument specifies an existing user class, the command must be run
-as root, or the \fBsudo\fR command must be run from a shell that is already
-root. This option is only available on systems with \s-1BSD\s0 login classes.
-.IP "\-E" 4
+.IP "\-C \fIfd\fR" 12
+.IX Item "-C fd"
+Normally, \fBsudo\fR will close all open file descriptors other than
+standard input, standard output and standard error. The \fB\-C\fR
+(\fIclose from\fR) option allows the user to specify a starting point
+above the standard error (file descriptor three). Values less than
+three are not permitted. This option is only available if the
+administrator has enabled the \fIclosefrom_override\fR option in
+\&\fIsudoers\fR\|(@mansectform@).
+@LCMAN@.IP "\-c \fIclass\fR" 12
+@LCMAN@.IX Item "-c class"
+@LCMAN@The \fB\-c\fR (\fIclass\fR) option causes \fBsudo\fR to run the specified command
+@LCMAN@with resources limited by the specified login class. The \fIclass\fR
+@LCMAN@argument can be either a class name as defined in \fI/etc/login.conf\fR,
+@LCMAN@or a single '\-' character. Specifying a \fIclass\fR of \f(CW\*(C`\-\*(C'\fR indicates
+@LCMAN@that the command should be run restricted by the default login
+@LCMAN@capabilities for the user the command is run as. If the \fIclass\fR
+@LCMAN@argument specifies an existing user class, the command must be run
+@LCMAN@as root, or the \fBsudo\fR command must be run from a shell that is already
+@LCMAN@root. This option is only available on systems with \s-1BSD\s0 login classes.
+.IP "\-E" 12
.IX Item "-E"
The \fB\-E\fR (\fIpreserve\fR \fIenvironment\fR) option will override the
\&\fIenv_reset\fR option in \fIsudoers\fR\|(@mansectform@)). It is only
available when either the matching command has the \f(CW\*(C`SETENV\*(C'\fR tag
or the \fIsetenv\fR option is set in \fIsudoers\fR\|(@mansectform@).
-.IP "\-e" 4
+.IP "\-e" 12
.IX Item "-e"
The \fB\-e\fR (\fIedit\fR) option indicates that, instead of running
a command, the user wishes to edit one or more files. In lieu
of a command, the string \*(L"sudoedit\*(R" is used when consulting
the \fIsudoers\fR file. If the user is authorized by \fIsudoers\fR
the following steps are taken:

-nor \f(CW\*(C`EDITOR\*(C'\fR are set, the program listed in the \fIeditor\fR \fIsudoers\fR

.RE
-.IP "\-H" 4
+.IP "\-g \fIgroup\fR" 12
+.IX Item "-g group"
+Normally, \fBsudo\fR sets the primary group to the one specified by
+the passwd database for the user the command is being run as (by
+default, root). The \fB\-g\fR (\fIgroup\fR) option causes \fBsudo\fR to run
+the specified command with the primary group set to \fIgroup\fR. To
+specify a \fIgid\fR instead of a \fIgroup name\fR, use \fI#gid\fR. When
+running commands as a \fIgid\fR, many shells require that the '#' be
+escaped with a backslash ('\e'). If no \fB\-u\fR option is specified,
+the command will be run as the invoking user (not root). In either
+case, the primary group will be set to \fIgroup\fR.
+.IP "\-H" 12
.IX Item "-H"
The \fB\-H\fR (\fI\s-1HOME\s0\fR) option sets the \f(CW\*(C`HOME\*(C'\fR environment variable
to the homedir of the target user (root by default) as specified
in \fIpasswd\fR\|(@mansectform@). By default, \fBsudo\fR does not modify \f(CW\*(C`HOME\*(C'\fR
(see \fIset_home\fR and \fIalways_set_home\fR in \fIsudoers\fR\|(@mansectform@)).
-.IP "\-h" 4
+.IP "\-h" 12
.IX Item "-h"
The \fB\-h\fR (\fIhelp\fR) option causes \fBsudo\fR to print a usage message and exit.
-.IP "\-i" 4
-.IX Item "-i"
+.IP "\-i [command]" 12
+.IX Item "-i [command]"
The \fB\-i\fR (\fIsimulate initial login\fR) option runs the shell specified
-in the \fIpasswd\fR\|(@mansectform@) entry of the user that the command is
-being run as. The command name argument given to the shell begins
-with a `\f(CW\*(C`\-\*(C'\fR' to tell the shell to run as a login shell. \fBsudo\fR
-attempts to change to that user's home directory before running the
-shell. It also initializes the environment, leaving \fI\s-1TERM\s0\fR
-unchanged, setting \fI\s-1HOME\s0\fR, \fI\s-1SHELL\s0\fR, \fI\s-1USER\s0\fR, \fI\s-1LOGNAME\s0\fR, and
-\&\fI\s-1PATH\s0\fR, and unsetting all other environment variables. Note that
-because the shell to use is determined before the \fIsudoers\fR file
-is parsed, a \fIrunas_default\fR setting in \fIsudoers\fR will specify
-the user to run the shell as but will not affect which shell is
-actually run.
-.IP "\-K" 4
+in the \fIpasswd\fR\|(@mansectform@) entry of the target user as a login shell. This
+means that login-specific resource files such as \f(CW\*(C`.profile\*(C'\fR or
+\&\f(CW\*(C`.login\*(C'\fR will be read by the shell. If a command is specified,
+it is passed to the shell for execution. Otherwise, an interactive
+shell is executed. \fBsudo\fR attempts to change to that user's home
+directory before running the shell. It also initializes the
+environment, leaving \fI\s-1DISPLAY\s0\fR and \fI\s-1TERM\s0\fR unchanged, setting
+\&\fI\s-1HOME\s0\fR, \fI\s-1SHELL\s0\fR, \fI\s-1USER\s0\fR, \fI\s-1LOGNAME\s0\fR, and \fI\s-1PATH\s0\fR, as well as

.IX Item "-K"
The \fB\-K\fR (sure \fIkill\fR) option is like \fB\-k\fR except that it removes
-the user's timestamp entirely. Like \fB\-k\fR, this option does not
-require a password.
-.IP "\-k" 4
+the user's timestamp entirely and may not be used in conjunction

+.IP "\-k" 12
.IX Item "-k"
-The \fB\-k\fR (\fIkill\fR) option to \fBsudo\fR invalidates the user's timestamp
-by setting the time on it to the Epoch. The next time \fBsudo\fR is
-run a password will be required. This option does not require a password
-and was added to allow a user to revoke \fBsudo\fR permissions from a .logout
-file.
-.IP "\-L" 4
+When used by itself, the \fB\-k\fR (\fIkill\fR) option to \fBsudo\fR invalidates
+the user's timestamp by setting the time on it to the Epoch. The
+next time \fBsudo\fR is run a password will be required. This option
+does not require a password and was added to allow a user to revoke
+\&\fBsudo\fR permissions from a .logout file.
+.Sp
+When used in conjunction with a command or an option that may require
+a password, the \fB\-k\fR option will cause \fBsudo\fR to ignore the user's
+timestamp file. As a result, \fBsudo\fR will prompt for a password
+(if one is required by \fIsudoers\fR) and will not update the user's
+timestamp file.
+.IP "\-L" 12
.IX Item "-L"
The \fB\-L\fR (\fIlist\fR defaults) option will list out the parameters
that may be set in a \fIDefaults\fR line along with a short description
for each. This option is useful in conjunction with \fIgrep\fR\|(1).
-.IP "\-l" 4
-.IX Item "-l"
-The \fB\-l\fR (\fIlist\fR) option will list out the allowed (and
-forbidden) commands for the invoking user on the current host.
-.IP "\-P" 4
+.IP "\-l[l] [\fIcommand\fR]" 12
+.IX Item "-l[l] [command]"

+\&\fIcommand\fR is specified and is permitted by \fIsudoers\fR, the
+fully-qualified path to the command is displayed along with any
+command line arguments. If \fIcommand\fR is specified but not allowed,
+\&\fBsudo\fR will exit with a status value of 1. If the \fB\-l\fR option is
+specified with an \fBl\fR argument (i.e. \fB\-ll\fR), or if \fB\-l\fR
+is specified multiple times, a longer list format is used.
+.IP "\-n" 12
+.IX Item "-n"
+The \fB\-n\fR (\fInon-interactive\fR) option prevents \fBsudo\fR from prompting
+the user for a password. If a password is required for the command
+to run, \fBsudo\fR will display an error messages and exit.
+.IP "\-P" 12

The \fB\-P\fR (\fIpreserve\fR \fIgroup vector\fR) option causes \fBsudo\fR to
preserve the invoking user's group vector unaltered. By default,
