SYNOPSIS
getfacl [OPTIONS] files...
DESCRIPTION
getfacl displays file access control lists (ACLs). ACLs provide more fine-grained access control than traditional Unix permissions, allowing permissions for specific users and groups beyond owner/group/other.
PARAMETERS
-n, --numeric
Display numeric user and group IDs-t, --tabular
Use tabular output format-a, --access
Display access ACL-d, --default
Display default ACL-R, --recursive
Recurse into directories-p, --absolute-names
Don't strip leading slashes
INSTALL
sudo apt install acl
sudo dnf install acl
sudo pacman -S acl
sudo apk add acl
sudo zypper install acl
brew install acl
nix profile install nixpkgs#acl
CAVEATS
ACLs must be supported by the filesystem (mount with acl option). The default ACL only applies to directories and affects newly created files within. Use setfacl to modify ACLs.
HISTORY
getfacl is part of the acl package, providing POSIX ACL support on Linux.
