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
Since the
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
-F flag 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 -R
flag.
-
-
- -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 preserved package. Note that this is a dangerous
operation. See also the -k option.
-
-
- -K
pkg_dbdir
- Override the value of the
PKG_DBDIR
configuration 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 @unexec lines 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.
-
-
- -P
destdir
- Prefix all file and directory names with
destdir. For packages without install scripts this
has the same behavior as using
chroot(8).
-
-
- -p
prefix
- 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
-A flag.
-
-
- -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⟩
DEINSTALL
before deleting all files and as:
deinstall
⟨pkg-name⟩
POST-DEINSTALL
after deleting them. Passing the keywords
DEINSTALL and
POST-DEINSTALL 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
-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.
