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.
