NAME

pathchk — check pathname validity

SYNOPSIS

DESCRIPTION

pathchk checks each pathname for their validity and portability.

By default, pathchk does the following checks, based on the underlying filesystem:

• Isn't longer than PATH_MAX
• Doesn't have any path component longer than NAME_MAX
• Is reachable to the current user
• Doesn't contains invalid bytes

Note that non-existing path components aren't seen as an error by pathchk.

OPTIONS

-p

Do not perform checks against the underlying filesystem, meaning:

• _POSIX_PATH_MAX is used instead of PATH_MAX
• _POSIX_NAME_MAX is used instead of NAME_MAX
• Directories aren't checked for user reachability
• POSIX Portable Character Set is the only reference for invalid byte sequences

-P

Perform the following additional checks:

• Doesn't contains a path component whose first character is the <hyphen-minus> character
• Isn't empty

EXIT STATUS

The pathchk utility exits 0 on success, and >0 if an error occurs.
