NAME    [Toc]    [Back]

     pathchk -- check pathnames

SYNOPSIS    [Toc]    [Back]

     pathchk [-p] pathname ...

DESCRIPTION    [Toc]    [Back]

     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
		 component may start with the hyphen (`-') character.

EXAMPLES    [Toc]    [Back]

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

	   find . -print | xargs pathchk -p
