PATHCHK(1)                  General Commands Manual                 PATHCHK(1)

     pathchk - check pathnames

     pathchk [-p] pathname ...

     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

     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.

     Check whether the names of files in the current directory are portable to
     other POSIX systems:

           find . -exec pathchk -p \{\} +
     or the more efficient:
           find . -print0 | xargs -0 pathchk -p

     getconf(1), pathconf(2), stat(2)

     The pathchk utility conforms to IEEE Std 1003.1-2001 ("POSIX.1").

     A pathchk utility appeared in NetBSD 2.0.
