pathchk -- check pathnames SYNOPSIS
pathchk [-pP] 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. -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
