pkg_add
command is used to install packages created
with the pkg_create(1)
command. Selected packages containing pre-compiled applications from the
/usr/ports tree can be found on the
OpenBSD FTP site or on the official
OpenBSD CD.
pkg_add
.pkg_add
can be used to install new
packages, to replace existing packages with other flavors (option
-r
) or to update packages to newer versions (option
-u
).
Details of packing-list internals are documented in pkg_create(1).
pkg_add
will
syslog(3) installations and
updates by default (but see
pkg.conf(5)).
If a package is digitally signed:
pkg_add
checks that its packing-list is not
corrupted and matches the cryptographic signature stored within.pkg_add
verifies that the signature was emitted by
a valid user certificate, signed by one of the authorities in
/etc/ssl/pkgca.pempkg_add
verifies that each file matches its sha256
checksum right after extraction, before doing anything with it.pkg_add
verifies that any dangerous mode or owner
is registered in the packing-list.In normal mode, the package names given on the command lines are
names of new packages that pkg_add
should install,
without ever deinstalling existing packages.
In replacement mode, the package names given on the command lines
are names of new packages that pkg_add
should
install, possibly replacing existing installed packages.
In update mode, the package names given on the command lines are
names of installed packages, and pkg_add
should
figure out newer package names for these, then replace the old packages with
the new.
Each package name may be specified as a filename (which normally consists of the package name itself plus the “.tgz” suffix) or a URL referring to FTP, HTTP, HTTPS, or SCP locations. The following examples are valid:
pkg_add -v
ftp://ftp.openbsd.org/pub/OpenBSD/2.7/packages/i386/m4-1.4.tgz
pkg_add -v
scp://login@host/usr/ports/packages/sparc/all/tcl-8.4.7.tgz
If the given package names are not found in the current working
directory, pkg_add
will search for them in each
directory named by the PKG_PATH
environment
variable. Specifying ‘-
’ as a package
name causes pkg_add
to read from the standard
input.
pkg_add
also understands
‘stems’, that is, package names without any version
specification. For instance, with pkg_add kdelibs
,
pkg_add
will look in the current directory (or the
PKG_PATH) for a kdelibs package.
In case of ambiguities, for instance: pkg_add
screen
(matches screen-4.02 and screen-4.02-static),
pkg_add
will error out, unless it is invoked in
interactive mode (option -i
).
To avoid ambiguities, pkg_add
supports
‘stems with flavors’, that is, a stem separated from flavors
with a double dash. For instance, the previous ambiguity could be resolved
by using pkg_add screen--
(matches only the normal
flavor) or pkg_add screen--static
(matches only the
static flavor).
If the environment variable PKG_CACHE
is
set to a directory name, every package retrieved from a distant location
will also be copied here.
Some packages may depend on other packages. When resolving
dependencies pkg_add
will first look at already
installed packages, then match dependencies with the list of packages left
to install, then ask the user's opinion in interactive mode, then install
default packages that satisfy the dependencies.
Alternatively, it is possible to add packages interactively from
within the ftp(1) client, in
which case setting PKG_PATH
correctly will be
necessary for any dependency to be found out and retrieved the same way. For
example, the following works:
$ ftp ftp://ftp.openbsd.org/pub/OpenBSD/2.7/packages/i386/ 250 CWD command successful ftp> ls m* 227 Entering Passive Mode (129,128,5,191,164,73) 150 Opening ASCII mode data connection for m*. m4-1.4.tgz metamail-2.7.tgz mh-6.8.4.tgz mm-1.0.12.tgz mpeg_lib-1.2.1.tgz mpeg_play-2.4.tgz mpg123-0.59q.tgz mutt-0.95.7i.tgz 226 Transfer complete. ftp> get m4-1.4.tgz "|pkg_add -v -"
Warning: Since the
pkg_add
command may execute scripts or programs
contained within a package file, your system may be susceptible to
“trojan horses” or other subtle attacks from miscreants who
create dangerous packages. Be sure the specified package(s) are from trusted
sources.
The options are as follows:

sure everything stays in synch. -D
dontmerge disables that behavior.pkg_add
will try to find new files
in old packages by comparing the stored sha256, and tie the entries
together to avoid extracting files needlessly.
-D

behavior.-i

-r
pkg_add
will try to
take every precaution to make sure the replacement can proceed before
removing the old package and adding the new one, and it should also handle
shared libraries correctly. Among other things,
pkg_add
will refuse to replace packages as soon as
it needs to run scripts that might fail (use -D
update to force the replacement);
pkg_add
will also refuse to replace packages when
the dependencies don't quite match (use -D
updatedepends to force the replacement).-s

, except it also skips fetching full packages
and stops at getting the information it needs.-U

pkg_add

relies on PKG_PATH
to figure out the new package
names.-v
-v
turn on more
verbose output. By default, pkg_add
is almost
completely silent, but it reacts to keyboard status requests (see
stty(1)).
-v
turns on basic messages,
-vv
adds relevant system operations,
-vvv
shows most internal computations apart from
individual file/directory additions, -vvvv
also
shows dependencies adjustments, and -vvvvv
shows
everything.-x
-z
pkg_add
should do its best
to match package names passed on the command line, even if the versions
don't match and it will proceed even if some packages can't be found.By default, when adding packages via FTP, the
ftp(1) program operates in
“passive” mode. If you wish to use active mode instead, set
the FTPMODE
environment variable to
“active”. If pkg_add
consistently
fails to fetch a package from a site known to work, it may be because the
site does not support passive mode FTP correctly. This is very rare since
pkg_add
will try active mode FTP if the server
refuses a passive mode connection.
pkg_add
differentiates between packages specified on the
command line, and packages installed automatically because of
inter-dependencies: the first kind will be tagged as ‘installed
manually’. The -a
option is used internally by
the ports(7) infrastructure and
dpb(1) to handle dependencies.
It is also possible to tweak the ‘installed
manually’ status of a package after the fact. Running
pkg_add
on an already installed package will tag it
as ‘installed manually’, even if it was already there as a
dependency of something else, and doubling the -a
option will remove the ‘installed manually’ tag from installed
packages.
pkg_info(1) can be used to show only manually-installed packages, and pkg_delete(1) can be used to remove dependencies when they are no longer needed.
pkg_add
deals with ‘updatesets’
internally. An updateset is a collection of old package(s) to delete, and new
package(s) to install, as an atomic operation. Under normal circumstances, an
updateset contains at most one old package and one new package, but some
situations may require pkg_add
to perform several
installations/deletions at once.
For each new package in an updateset,
pkg_add
extracts the package's “packing
information” (the packing-list, description, and
installation/deinstallation scripts) into a special staging directory in
/var/tmp (or PKG_TMPDIR
if
set - see CAVEATS, below) and then runs
through the following sequence to fully extract the contents of the
package:
@conflict
directives; see
pkg_create(1)) with a
package already recorded as installed. In non-replacement mode, its
installation is terminated.pkg_add
verifies that the current machine
architecture agrees with the constraints.@depend
and
@wantlib
directives; see
pkg_create(1)) are read
from the packing-list. If any of these dependencies are not currently
fulfilled, an attempt is made to find a package that meets them and
install it, looking first in the current updateset, then in the list of
packages to install passed to pkg_add
; if no
adequate package can be found and installed, the installation is
terminated.pkg_add
checks for collisions with installed file
names, read-only file systems, and enough space to store files.@exec
is more versatile), it is
executed with the following arguments:
PRE-INSTALL
If the install script exits with a non-zero status code, the installation is terminated.
POST-INSTALL
PKG_DBDIR
is set,
this overrides the /var/db/pkg/ path shown
above).Note that it is safe to interrupt pkg_add
through SIGINT
, SIGHUP
, and
other signals, as it will safely record an interrupted install as
partial-<pkgname>[.n].
When replacing packages, the procedure is slightly different.
pkg_add
will attempt to
update those packages. If they update to the new package(s), nothing needs
to be done. If they're part of the list of updatesets to install, the
corresponding updatesets will be merged. Otherwise,
pkg_add
will add them to the current updateset,
and rerun update to find suitable update to those packages.@unexec-delete
commands are not executed.@exec-add
commands are not executed.To update packages in -u mode, pkg_add
performs the following steps.
PKG_PATH
is
considered as an update candidate.pkg_add
searches for a ‘quirks’
package first, which may contain exceptions to these rules. This special
package contains global information, such as packages that can be deleted
because they're now part of base, or stem changes.PKG_PATH
should point to
a snapshot of packages for a given version of
OpenBSD, similar to the organization on the FTP
sites.pkg_add
will ask
the user in interactive mode, and not perform the update in
non-interactive mode.pkg_add
checks the package dependencies. If
necessary, it will install or update them first. Once all dependencies are
up-to-date, pkg_add
will update the package.FTPMODE

seconds, so that incorrectly

PKG_PATH
PKG_PATH
are searched. It should contain a series
of entries separated by colons. Each entry consists of a directory name.
URL schemes such as FTP, HTTP, HTTPS, or SCP are also appropriate. The
current directory may be indicated implicitly by an empty directory name,
or explicitly by a single period
(‘./
’).PKG_TMPDIR
If /var/tmp is mounted noexec, you must
currently set PKG_TMPDIR
to a suitable area, as
pkg_add
will refuse to install any package that
contains executable scripts.
