PATHCHK(1) BSD General Commands Manual PATHCHK(1)
NAME
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
Check whether the names of files in the current directory are portable to other POSIX systems:
find . -exec pathchk -p -- {} +
