.Xc
List project identifier (ID) and inherit flag of file(s) or directories.
.Bl -tag -width "-d"
.It Fl d

overwrite the former specified
.Fl r
option.
.It Fl r
Show on subdirectories recursively. It will overwrite the former specified
.Fl d
option.

.Bl -tag -width "-k"
.It Fl k
Keep the project ID unchanged. If not specified, the project ID will be reset
as zero.
.It Fl r
Clear on subdirectories recursively.

.Oo Fl 0 Ns Oc
.Oo Fl d Ns | Ns Fl r Ns Oc
.Op Fl p Ar id
.Ar file Ns | Ns Ar directory Ns ...
.Xc
Check project ID and inherit flag on the file(s) or directories, report the
entries without project inherit flag or with different project IDs from the
specified (via
.Fl p
option) value or the target directory's project ID.
.Bl -tag -width "-0"
.It Fl 0
Print file name with a trailing NUL instead of newline (by default), like
"find -print0".
.It Fl d
Check the directory project ID and inherit flag, not its children. It will
overwrite the former specified
.Fl r
option.
.It Fl p
Specify the referenced ID for comparing with the target file(s) or directories'
project IDs. If not specified, the target (top) directory's project ID will be
used as the referenced one.
.It Fl r
Check on subdirectories recursively. It will overwrite the former specified
.Fl d

.Bl -tag -width "-p"
.It Fl p
Set the file(s)' or directories' project ID with the given value.
.It Fl r
Set on subdirectories recursively.
.It Fl s
Set project inherit flag on the given file(s) or directories. It is usually used
for setup tree quota on the directory target with
.Fl r
option specified together. When setup tree quota, by default the directory's
project ID will be set to all its descendants unless you specify the project
ID via
.Fl p
option explicitly.
