Set default ACL on Linux

Filed under: UNIX & Linux — martin @ 2:45 pm

Challenge: User1 has a world-writable directory. User2 has umask 077 set and writes into User1’s world writable directory. User1 can’t read those files.

Workaround: Short of User 2 setting his umask properly, set a default ACL on the directory:

setfacl -d -m user::rw,group::rw,other::r /path/to/User1/incoming/
