PATHCHK(1) General Commands Manual PATHCHK(1)
pathchk – check pathnames
pathchk [-p] pathname ...
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.
Check whether the names of files in the current directory are portable to
other POSIX systems:
find . -print | xargs pathchk -p
The pathchk utility exits 0 on success, and >0 if an error occurs.
