Summary

This page will record my efforts to learn how to use POSIX ACLs. I'm familiar with ACLs used on Windows systems and to a lesser extent Mac OS X (GUI-only), but this is my first foray into POSIX ACLs.

TODO

  • Move general permissions info (references, notes, etc) to another page

References

ACLs

umask

h5. chmod, chown and sticky bits

h5. General permissions

---

Goals:

Explain stuff like:

  • @chmod 2755@
  • @setfacl -d -m group:rwx /path/to/your/dir@
