NAME
pkg_delete —
a utility for deleting previously
installed software package distributions
SYNOPSIS
pkg_delete |
[-ADFfkNnORrVv] [-K
pkg_dbdir] [-P
destdir] [-p
prefix] pkg-name ... |
DESCRIPTION
The pkg_delete command is used to delete
packages that have been previously installed with the
pkg_add(1) command. The given packages are sorted, so that the
dependencies needed by a package are deleted after the package. Before any
action is executed, pkg_delete checks for packages
that are marked as preserved or have depending
packages left. If the -k flag is given, preserved
packages are skipped and not removed. Unless the -f
flag is given, pkg_delete stops on the first
error.
WARNING
pkg_delete command may
execute scripts or programs provided by a package file, your system may be
susceptible to “Trojan horses” or other subtle attacks from
miscreants who create dangerous package files.
You are advised to verify the competence and identity of those who
provide installable package files. For extra protection, examine all the
package control files in the package record directory
<PKG_DBDIR>/<pkg-name>/). Pay particular
attention to any +INSTALL or
+DEINSTALL files, and inspect the
+CONTENTS file for @cwd,
@mode (check for setuid),
@dirrm, @exec, and
@unexec directives, and/or use the
pkg_info(1) command to examine the installed package control
files.
OPTIONS
The following command line options are supported:
- pkg-name ...
- 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
-Fflag is given, one or more (absolute) filenames may be specified and the package database will be consulted for the package to which the given file belongs. These packages are then deinstalled. -A- Recursively remove all automatically installed packages that were needed
by the given packages and are no longer required. Does not remove manually
installed packages; see also the
-Rflag. -D- If a deinstallation script exists for a given package, do not execute it.
-F- Any pkg-name given will be interpreted as pathname which is subsequently 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.
-f- Force removal of the package, even if a dependency is recorded or the deinstall script fails. This might break the package database; see pkg_admin(1) on how to repair it.
-ff- Force removal of the package, even if the package is marked as a
preservedpackage. Note that this is a dangerous operation. See also the-koption. -Kpkg_dbdir- Override the value of the
PKG_DBDIRconfiguration option with the value pkg_dbdir. -k- Silently skip all packages that are marked as
preserved. -N- Remove the package's registration and its entries from the package
database, but leave the files installed. Don't run any deinstall scripts
or
@unexeclines either. -n- Don't actually deinstall a package, just report the steps that would be taken.
-O- Only delete the package's entries from the package database; do not touch the package or its files itself.
-Pdestdir- Prefix all file and directory names with destdir. For packages without install scripts this has the same behavior as using chroot(8).
-pprefix- Set prefix 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).
-R- Recursively remove all packages that were needed by the given packages and
are no longer required. This option overrides the
-Aflag. -r- Recursively remove all packages that require one of the packages given.
-V- Print version number and exit.
-v- Turn on verbose output.
TECHNICAL DETAILS
pkg_delete does pretty much what it says.
It examines installed package records in
<PKG_DBDIR>/<pkg-name>, deletes the
package contents, and finally removes the package records.
If a package is required by other installed packages,
pkg_delete will list those dependent packages and
refuse to delete the package (unless the -f option
is given).
If a package has been marked as a
preserved package, it will not be able to be deleted
(unless more than one occurrence of the -f 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
-F flag is given. The filename needs to be absolute,
see the output produced by the
pkg_info(1) -aF command.
If a deinstall 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 pkg_delete knows
how to do is delete the files created in the original distribution. The
deinstall script is called as:
deinstall
⟨pkg-name⟩
DEINSTALLdeinstall
⟨pkg-name⟩
POST-DEINSTALLAll scripts are called with the environment variable
PKG_PREFIX set to the installation prefix (see the
-p option above). This allows a package author to
write a script that reliably performs some action on the directory where the
package is installed, even if the user might have changed it by specifying
the -p option when running
pkg_delete or
pkg_add(1). The scripts are also called with the
PKG_METADATA_DIR environment variable set to the
location of the +* meta-data files, and with the
PKG_REFCOUNT_DBDIR environment variable set to the
location of the package reference counts database directory. If the
-P flag was given to
pkg_delete, PKG_DESTDIR will
be set to destdir.
ENVIRONMENT
See pkg_install.conf(5) for options, that can also be specified using the environment.
