NAME
pathchk
- check pathnames
SYNOPSIS
pathchk
[-p]
pathname ...
DESCRIPTION
The
pathchk
utility checks whether each of the specified
pathname
arguments is valid or portable.
A diagnostic message is written for each argument that:
-
Is longer than
PATH_MAX
bytes.
-
Contains any component longer than
NAME_MAX
bytes.
(The value of
NAME_MAX
depends on the underlying file system.)
-
Contains a directory component that is not searchable.
It is not considered an error if a
pathname
argument contains a nonexistent component as long as a component by that
name could be created.
The options are as follows:
- -p
-
Perform portability checks on the specified
pathname
arguments.
Diagnostic messages will be written for each argument that:
-
Is longer than
_POSIX_PATH_MAX
(255)
bytes.
-
Contains a component longer than
_POSIX_NAME_MAX
(14)
bytes.
-
Contains any character not in the portable filename character set (that is,
alphanumeric characters,
`.',
`-'
and
`_').
No component may start with the hyphen
(`-')
character.
EXAMPLES
Check whether the names of files in the current directory are portable to
other
POSIX
systems:
find . -print | xargs pathchk -p
