\&\fBvisudo\fR accepts the following command line options:

.Ip "\-c" 4

.IP "\-c" 4

.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

Line 222

Line 213

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

.IP "\-f" 4

.IX Item "-f"

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, \f(CW@sysconfdir\fR@/sudoers. The lock file used

is the specified \fIsudoers\fR file with \*(L".tmp\*(R" appended to it.

.Ip "\-q" 4

.IP "\-q" 4

.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

.IP "\-s" 4

.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

letters, digits, and the underscore ('_') character.

.Ip "\-V" 4

.IP "\-V" 4

.IX Item "-V"

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

and exit.
