.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility checks whether each of the specified
|
|
.Ar pathname
|
|
arguments is valid or portable.
|
|
.Pp
|
|
A diagnostic message is written for each argument that:
|
|
.Bl -bullet
|
|
.It
|
|
Is longer than
|
|
.Dv PATH_MAX
|
|
bytes.
|
|
.It
|
|
Contains any component longer than
|
|
.Dv NAME_MAX
|
|
bytes.
|
|
(The value of
|
|
.Dv NAME_MAX
|
|
depends on the underlying file system.)
|
|
.It
|
|
Contains a directory component that is not searchable.
|
|
.El
|
|
.Pp
|
|
It is not considered an error if a
|
|
.Ar pathname
|
|
argument contains a nonexistent component as long as a component by that
|
|
name could be created.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl p
|
|
Perform portability checks on the specified
|
|
.Ar pathname
|
|
arguments.
|
|
Diagnostic messages will be written for each argument that:
|
|
.Bl -bullet
|
|
.It
|
|
Is longer than
|
|
.Dv _POSIX_PATH_MAX
|
|
.Pq 255
|
|
bytes.
|
|
.It
|
|
Contains a component longer than
|
|
.Dv _POSIX_NAME_MAX
|
|
.Pq 14
|
|
bytes.
|
|
.It
|
|
Contains any character not in the portable filename character set (that is,
|
|
alphanumeric characters,
|
|
.Ql \&. ,
|
|
.Ql \&-
|
|
and
|
|
.Ql _ ) .

No component may start with the hyphen
|
|
.Pq Ql \&-
|
|
character.
|
|
.El
|
|
.It Fl P
|
|
In addition to the default or
|
|
.Fl p
|
|
checks, write a diagnostic for each argument that:
|
|
.Bl -bullet
|
|
.It
|
|
Is empty.
|
|
.It
|
|
Contains a component that starts with a hyphen.
