.Os
.Sh NAME
.Nm getfacl
.Nd show Linux POSIX ACL information
.Sh SYNOPSIS
.Nm
.Op Fl dhnqs
.Op Ar file ...
.Sh DESCRIPTION
The
.Nm
utility writes Linux POSIX ACL information for each
.Ar file
to standard output.
This port reads ACLs directly from the Linux xattrs
.Pa system.posix_acl_access
and
.Pa system.posix_acl_default .
If an access ACL xattr is absent, the base ACL is synthesized from the file
mode bits.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl d , Fl -default
Show the default ACL instead of the access ACL.
If no default ACL xattr exists, only the header is printed unless
.Fl q
or
.Fl s
suppresses output.
.It Fl h
Do not follow symbolic links.
On Linux, POSIX ACLs are not supported on symbolic link inodes, so this port
returns an explicit error when
.Fl h
targets a symbolic link.
.It Fl n , Fl -numeric
Display numeric user and group identifiers instead of resolving names.
.It Fl q , Fl -omit-header
Suppress the commented file, owner, and group header.
.It Fl s , Fl -skip-base
Skip access ACLs that are trivial and can be represented entirely by the file
mode bits.
For default ACLs, suppress output when no default ACL xattr exists.
.It Fl i
Unsupported on Linux in this port.
This flag was specific to FreeBSD NFSv4 ACL output and exits with an error.
.It Fl v
Unsupported on Linux in this port.
This flag was specific to FreeBSD NFSv4 ACL output and exits with an error.
.El
.Pp
If no
.Ar file
operand is provided, or if an operand is
.Fl - ,
.Nm
reads pathnames from standard input, one per line.
.Sh EXIT STATUS
.Ex -std
.Sh SEE ALSO
.Xr chmod 1 ,
.Xr setfacl 1 ,
.Xr getxattr 2 ,
.Xr lgetxattr 2 ,
.Xr stat 2 ,
.Xr xattr 7
.Sh HISTORY
Extended Attribute and Access Control List support was developed as part of
the
.Tn TrustedBSD
Project.
This Linux port replaces the original FreeBSD ACL library dependencies with a
Linux-native xattr parser.
