MPE/iX NOTES

The current MPE/iX implementation of chmod does not allow you to modify the access permis-

sions of the root directory, account directories, and group directories. Also, use of the sticky

bits is not allowed.

MPE/iX, chmod is available as both a built-in shell utility and an external utility.

For more information on how the current

MPE/iX implementation may affect the operation of

this utility, see Appendix A, MPE/iX Implementation Considerations.
