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:

     o	 Is longer than PATH_MAX bytes.

     o	 Contains any component longer than NAME_MAX bytes.  (The value of NAME_MAX depends on the underlying file system.)

     o	 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:

	     o	 Is longer than _POSIX_PATH_MAX (255) bytes.

	     o	 Contains a component longer than _POSIX_NAME_MAX (14) bytes.

	     o	 Contains any character not in the portable filename character set (that is, alphanumeric characters, '.', '-' and '_').  No com-
		 ponent may start with the hyphen ('-') character.

EXAMPLES

     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
