command scans the installed ports and show all UPDATING entries that affect one
of the installed ports. Alternative a list of pkg-names could be passed.
.Sh OPTIONS
The following command line options are supported:
.Bl -tag -width indent
.It Ar pkg-name ...
UPDATING entries for the named packages are displayed.
.It Fl d Ar date
Only entries newer than this date are shown. Use a YYYYMMDD date format.
.It Fl f Ar UPDATING file
Defines a alternative location of the UPDATING file.
.El
.Sh EXAMPLES
.Bl -tag -width indent
.Dl pkg_updating
.Pp
Shows all entries of all installed ports.
