PATHCHK(1) General Commands Manual PATHCHK(1)
NAME
pathchkcheck 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:
Is longer than PATH_MAX bytes.
Contains any component longer than NAME_MAX bytes. (The value of NAME_MAX depends on the underlying file system.)
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:
Is longer than _POSIX_PATH_MAX (255) bytes.
Contains a component longer than _POSIX_NAME_MAX (14) bytes.
Contains any character not in the portable filename character set (that is, alphanumeric characters, ‘.', ‘-' and ‘_'). No component may start with the hyphen (‘-') character.
EXAMPLES
Check whether the names of files in the current directory are portable to other POSIX systems:
 
find . -print | xargs pathchk -p
