PATHCHK(1)		FreeBSD	General	Commands Manual		    PATHCHK(1)

NAME
     pathchk --	check pathnames

SYNOPSIS
     pathchk [-pP] pathname ...

DESCRIPTION
     The pathchk utility checks	whether	each of	the specified pathname argu-
     ments 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 nonexis-
     tent 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
		 component may start with the hyphen (`-') character.

     -P	     In	addition to the	default	or -p checks, write a diagnostic for
	     each argument that:

	     +o	 Is empty.

	     +o	 Contains a component that starts with a hyphen.

EXIT STATUS
     The pathchk utility exits 0 on success, and >0 if an error	occurs.

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

	   find	. -exec	pathchk	-p -- {} +
