Hello, getconf. This is a slight reinvention of the
wheel^H^H^H^H^HPOSIX.2 and X/Open utility, and rather more complicated than necessary.

|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm getconf
|
||||
.Nd retrieve standard configuration variables
|
||||
.Sh SYNOPSIS
|
||||
.Nm getconf
|
||||
.Op Fl v Ar environment
|
||||
.Ar path_var
|
||||
.Ar file
|
||||
.Pp
|
||||
.Nm getconf
|
||||
.Op Fl v Ar environment
|
||||
.Ar system_var
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm getconf
|
||||
utility outputs the value of
|
||||
.Tn POSIX
|
||||
or
|
||||
.Tn X/Open
|
||||
system or path configuration variable on the standard output.
|
||||
If the specified variable is undefined, the string
|
||||
.Dq Li undefined
|
||||
is output.
|
||||
.Pp
|
||||
The first form of the command, with two mandatory
|
||||
arguments, retrieves file- and filesystem-specific
|
||||
configuration variables using
|
||||
.Xr pathconf 2 .
|
||||
The second form, with a single argument, retrieves system
|
||||
configuration variables using
|
||||
.Xr confstr 3
|
||||
and
|
||||
.Xr sysconf 3 ,
|
||||
depending on the type of variable.
|
||||
.Pp
|
||||
All variables use the same name as the manifest constants defined in
|
||||
the relevant standard C-language bindings, including any leading
|
||||
underscore or prefix.
|
||||
That is to say,
|
||||
.Ar system_var
|
||||
might be
|
||||
.Dv ARG_MAX
|
||||
or
|
||||
.Dv _POSIX_VERSION ,
|
||||
as opposed to the
|
||||
.Xr sysconf 3
|
||||
names
|
||||
.Dv _SC_ARG_MAX
|
||||
or
|
||||
.Dv _SC_POSIX_VERSION .
|
||||
(There is one exception: there is no corresponding manifest constant
|
||||
to
|
||||
.Dv _CS_PATH ,
|
||||
so a
|
||||
.Ar system_var
|
||||
of
|
||||
.Dq Li PATH
|
||||
is used.)
|
||||
.Pp
|
||||
The
|
||||
.Fl v Ar environment
|
||||
option is not supported, but provided for compatibility purposes.
|
||||
.Sh DIAGNOSTICS
|
||||
The
|
||||
.Nm getconf
|
||||
utility exits 0 on success or >0 if an error occurred.
|
||||
Use of a
|
||||
.Ar system_var
|
||||
or
|
||||
.Ar path_var
|
||||
which is completely unknown to the system is considered an error,
|
||||
causing a diagnostic message to be written to standard error; one
|
||||
which is known but merely undefined does not result in an error
|
||||
indication.
|
||||
.Pp
|
||||
Use of the unsupported
|
||||
.Fl v Ar environment
|
||||
option will result in a diagnostic message indicating that it is not
|
||||
supported.
|
||||
.Sh EXAMPLES
|
||||
The command:
|
||||
.Bd -literal -offset indent
|
||||
getconf PATH
|
||||
.Ed
|
||||
.Pp
|
||||
will display the system default setting for the
|
||||
.Ev PATH
|
||||
environment variable.
|
||||
.Pp
|
||||
The command:
|
||||
.Bd -literal -offset indent
|
||||
getconf NAME_MAX /tmp
|
||||
.Ed
|
||||
.Pp
|
||||
will display the maximum length of a filename in the
|
||||
.Pa /tmp
|
||||
directory.
|
||||
.Sh SEE ALSO
|
||||
.Xr confstr 3 ,
|
||||
.Xr pathconf 2 ,
|
||||
.Xr sysconf 3
|
||||
.Sh STANDARDS
|
||||
The
|
||||
.Nm getconf
|
||||
utility is expected to be compliant with
|
||||
.St -susv2 .
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm getconf
|
||||
command first appeared in
|
||||
.Fx 5.0 .
|
||||
.Sh BUGS
|
||||
The original
|
||||
.Tn X/Open
|
||||
specification erroneously requires the return values of
|
||||
.Xr pathconf 2
|
||||
and
|
||||
.Xr sysconf 3
|
||||
to be printed using the
|
||||
.Xr printf 3
|
||||
format specifier
|
||||
.Li \&"%d" .
|
||||
We ignore that aspect of the specification and use the
|
||||
correct
|
||||
.Li \&"%ld"
|
||||
format.
