I want to create a folder, so the owner can create and read files but not be able to delete them. I tried with ACL, but the owner can still delete the files.
$ setfacl --set u::rwx,g::-,o::- control $ setfacl -d --set u::r-x,g::-,o::- control $ touch 1.txt $ ls -al 1.txt -r--------. 1 user group 1.txt $ rm 1.txt rm: remove write-protected regular empty file `1.txt'? y
