Giving a single user write permissions

rated 0 times [ 6] [ 0] / answers: 1 / hits: 3697 / 2 Years ago, sat, january 29, 2022, 7:20:20

I want to grant a single user write permissions to a directory owned by root over command line. With chmod, it seems that I can only change the permissions for owner, group and other, not for a specific user.

If filesystem is mounted with the acl option (default in ext4 in any modern Ubuntu - if not, add it to /etc/fstab), you can use setfacl:

setfacl -m u:USERNAME:r FILENAME

would give user USERNAME read access to FILENAME.
