Hi Andreas, Here's a few more comments on the current getrichacl(1) page that I fetched from the git repo.

[" file ]... .SH DESCRIPTION For each file, .B getrichacl displays the file name and the file's Rich Access Control List (RichACL). The output format of .B getrichacl is as follows:
Add a blank line here.
.fam C .RS .nf 1: file: 2: flags:a 3: owner:rwp-------------::mask 4: group:r-p-------------::mask 5: other:r---------------::mask 6: owner@:rwp-------------::allow 7: user:foo:r-p-------------::allow 8: group@:r-p-------------::allow 9: group:bar:r-p-------------::allow 10: everyone@:r---------------::allow 11: .fi .RE .fam T Line 1 contains the file name, followed by a colon. Line 2 contains the ACL flags. This line is omitted if no flags are set. Lines 3--5 indicate the owner, group, and other file masks, which are only shown if the \fB\-\-raw\fR option is specified. Lines 6--10 indicate different ACL entries for the file owner .RB ( owner@ ), user \fIfoo\fR, the owning group .RB ( group@ ), group \fIbar\fR, and for everyone .RB ( everyone@ ). A blank line follows at the end. The default output format uses the single-letter forms of flags and permissions, identifiers of ACL entries are right justified, permissions are vertically aligned, and permissions which are always granted .RB ( read_attributes ", " read_acl ", " synchronize ) are omitted. See the .BR richacl (7) manual page for the defined flags and permissions. By default, .B getrichacl displays the effective permissions remaining after applying the file masks to the ACL. The file masks and underlying NFSv4 ACL can be displayed with the \fB\-\-raw\fR option. When .B getrichacl is used on a file that does not have a RichACL or on a filesystem that does not support RichACLs, .B getrichacl
Replace the previous line with "it".
displays the access permissions defined by the traditional file permission bits as a RichACL. When .B getrichacl is used on a file that has a POSIX ACL (see .BR acl (5)), it prints an error message. .SH OPTIONS .TP \fB\-\-long\fR, \fB\-l\fR Display access masks and flags in their long form. .TP \fB\-\-full\fR Also show permissions which are always implicitly allowed. .TP \fB\-\-raw\fR Show ACLs as stored on the file system, including the file masks. Implies \fB\-\-full\fR. .TP \fB\-\-unaligned\fR Do not align ACL entries or pad missing permissions with '-'. .TP \fB\-\-numeric-ids\fR Display numeric user and group IDs instead of names. .TP \fB\-\-access\fR [=\fIuser\fR[:\fIgroup\fR:...]}, \fB\-a\fR[\fIuser\fR[:\fIgroup\fR:...]} Instead of showing the ACL, show which permissions the user running the command has for the specified file(s). When \fIuser\fR is specified, show which permissions the specified user has instead. If \fIuser\fR is followed by a colon and a (possibly empty) list of groups, assume that \fIuser\fR is a member in the specified groups; otherwise, .BR getgrouplist (3) is used to determine the groups \fIuser\fR is a member in.
