- Check pathnames for validity on a wider range of POSIX compliant systems:

`pathchk -p {{path1 path2 …}}`

- Check pathnames for validity on all POSIX compliant systems:

`pathchk --portability {{path1 path2 …}}`

- Only check for empty pathnames or leading dashes (-):

`pathchk -P {{path1 path2 …}}`
