||||
.Nd check pathnames
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Fl p
|
||||
.Ar pathname ...
|
||||
.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
|
||||
.El
|
||||
.Sh EXAMPLES
|
||||
Check whether the names of files in the current directory are portable to
|
||||
other
|
||||
.Tn POSIX
|
||||
systems:
|
||||
.Pp
|
||||
.Dl "find . -exec pathchk -p \e{\e} +"
|
||||
or the more efficient:
|
||||
.Dl "find . -print0 | xargs -0 pathchk -p"
