.SH "OPTIONS"

\&\fBvisudo\fR accepts the following command line options:
-.IP "\-c" 4
+.IP "\-c" 12
.IX Item "-c"
Enable \fBcheck-only\fR mode. The existing \fIsudoers\fR file will be
checked for syntax and a message will be printed to the
If the syntax check completes successfully, \fBvisudo\fR will
exit with a value of 0. If a syntax error is encountered,
\&\fBvisudo\fR will exit with a value of 1.
-.IP "\-f" 4
-.IX Item "-f"
+.IP "\-f \fIsudoers\fR" 12
+.IX Item "-f sudoers"
Specify and alternate \fIsudoers\fR file location. With this option
\&\fBvisudo\fR will edit (or check) the \fIsudoers\fR file of your choice,
instead of the default, \fI@sysconfdir@/sudoers\fR. The lock file used
is the specified \fIsudoers\fR file with \*(L".tmp\*(R" appended to it.
-.IP "\-q" 4
+In \fBcheck-only\fR mode only, the argument to \fB\-f\fR may be \*(L"\-\*(R",
+indicating that \fIsudoers\fR will be read from the standard input.
+.IP "\-h" 12
+.IX Item "-h"
+The \fB\-h\fR (\fIhelp\fR) option causes \fBvisudo\fR to print a short help message
+to the standard output and exit.
+.IP "\-q" 12
.IX Item "-q"
Enable \fBquiet\fR mode. In this mode details about syntax errors
are not printed. This option is only useful when combined with
-the \fB\-c\fR flag.
-.IP "\-s" 4
+the \fB\-c\fR option.
+.IP "\-s" 12
.IX Item "-s"
Enable \fBstrict\fR checking of the \fIsudoers\fR file. If an alias is
used before it is defined, \fBvisudo\fR will consider this a parse
error. Note that it is not possible to differentiate between an
-alias and a hostname or username that consists solely of uppercase
+alias and a host name or user name that consists solely of uppercase
letters, digits, and the underscore ('_') character.
-.IP "\-V" 4

The \fB\-V\fR (version) option causes \fBvisudo\fR to print its version number
and exit.
