The ppkkgg__ddeelleettee command is used to delete packages that have been previ-
ously installed with the pkg_add(1) command.

OOPPTTIIOONNSS
The following command line options are supported:
_p_k_g_-_n_a_m_e _._._.
The named packages are deinstalled, wildcards can be used, see
pkg_info(1). If no version is given, the one currently installed
will be removed. If the --FF flag is given, one or more (absolute)
filenames may be specified and the Package Database will be con-
sulted for the package to which the given file belongs. These
packages are then deinstalled.
--DD If a deinstallation script exists for a given package, do not
execute it.
--dd Remove empty directories created by file cleanup. By default,
only files/directories explicitly listed in a package's contents
(either as normal files/directories or with the @@ddiirrrrmm directive)
will be removed at deinstallation time. This option tells
ppkkgg__ddeelleettee to also remove any directories that were emptied as a
result of removing the package.
--FF Any pkg-name given will be interpreted as pathname which is sub-
sequently transformed in a (real) package name via the Package
Database. That way, packages can be deleted by giving a filename
instead of the package-name.
--ff Force removal of the package, even if a dependency is recorded or
the deinstall or require script fails.
--KK _p_k_g___d_b_d_i_r
Set _p_k_g___d_b_d_i_r as the package database directory. If this option
isn't specified, then the package database directory is taken
from the value of the environment variable PKG_DBDIR if it's set,
otherwise it defaults to _/_v_a_r_/_d_b_/_p_k_g.
--nn Don't actually deinstall a package, just report the steps that
would be taken if it were.
--OO Only delete the package's entries from the package database, do
not touch the package or its files itself.
--pp _p_r_e_f_i_x
Set _p_r_e_f_i_x as the directory in which to delete files from any
installed packages which do not explicitly set theirs. For most
packages, the prefix will be set automatically to the installed
location by pkg_add(1).
--RR This option triggers a recursive delete of the given package and
any packages it depends on, unless some other package still needs
a dependent package. This --RR option can be used to clean up by
deleting a package and all its then-unneeded dependent packages.
--rr ppkkgg__ddeelleettee first builds a list of all packages that require
(directly and indirectly) the one being deleted. It then deletes
these packages using ppkkgg__ddeelleettee with the given options before
deleting the user specified package. This --rr option can be used
to recursively delete a package and all of the packages which
depend on that package.
--VV Print version number and exit.
--vv Turn on verbose output.
TTEECCHHNNIICCAALL DDEETTAAIILLSS
ppkkgg__ddeelleettee does pretty much what it says. It examines installed package
records in _/_v_a_r_/_d_b_/_p_k_g_/_<_p_k_g_-_n_a_m_e_>, deletes the package contents, and
finally removes the package records (if an alternate package database
directory is specified, then it overrides the _/_v_a_r_/_d_b_/_p_k_g path shown
above).
If a package is required by other installed packages, ppkkgg__ddeelleettee will
list those dependent packages and refuse to delete the package (unless
the --ff option is given).
If a package has been marked as a pprreesseerrvveedd package, it will not be able
to be deleted (unless more than one occurrence of the --ff option is
given).
If a filename is given instead of a package name, the package of which
the given file belongs to can be deleted if the --FF Flag is given. The
filename needs to be absolute, see the output produced by the pkg_info
--aaFF command.
If the package contains a _r_e_q_u_i_r_e file (see pkg_create(1)), then this is
executed first as
rreeqquuiirree _<_p_k_g_-_n_a_m_e_> _D_E_I_N_S_T_A_L_L
(where _p_k_g_-_n_a_m_e is the name of the package in question and _D_E_I_N_S_T_A_L_L is a
keyword denoting that this is a deinstallation) to see whether or not
deinstallation should continue. A non-zero exit status means no, unless
the --ff option is specified.
If a ddeeiinnssttaallll script exists for the package, it is executed before and
after any files are removed. It is this script's responsibility to clean
up any additional messy details around the package's installation, since
all ppkkgg__ddeelleettee knows how to do is delete the files created in the origi-
nal distribution. The ddeeiinnssttaallll script is called as:
ddeeiinnssttaallll _<_p_k_g_-_n_a_m_e_> _V_I_E_W_-_D_E_I_N_S_T_A_L_L
before removing the package from a view, and as:
ddeeiinnssttaallll _<_p_k_g_-_n_a_m_e_> _D_E_I_N_S_T_A_L_L
before deleting all files and as:
ddeeiinnssttaallll _<_p_k_g_-_n_a_m_e_> _P_O_S_T_-_D_E_I_N_S_T_A_L_L
after deleting them. Passing the keywords _V_I_E_W_-_D_E_I_N_S_T_A_L_L, _D_E_I_N_S_T_A_L_L and
_P_O_S_T_-_D_E_I_N_S_T_A_L_L lets you potentially write only one program/script that
handles all aspects of installation and deletion.
All scripts are called with the environment variable PKG_PREFIX set to
the installation prefix (see the --pp option above). This allows a package
author to write a script that reliably performs some action on the direc-
tory where the package is installed, even if the user might have changed
it by specifying the --pp option when running ppkkgg__ddeelleettee or pkg_add(1).
