.Dt PKG_CHK 8
.Sh NAME
.Nm pkg_chk
.Nd check, and optionally update, installed packages
.Sh SYNOPSIS
.Nm
.Op Fl aBbcfhiklNnpqrsuv
.Op Fl C Ar conf
.Op Fl D Ar tags
.Op Fl L Ar file
.Op Fl P Ar path
.Op Fl U Ar tags
.Sh DESCRIPTION
.Nm
verifies that the versions of installed packages matches those in
pkgsrc, optionally adding missing or updating mismatched packages.
.Pp
It can verify all installed packages, or check against a set of packages
based on the hostname, architecture, and other characteristics.
.Pp
When updating packages that depend on each other
.Nm
will skip dependent packages to reduce unnecessary rebuilding.
.Ss Options
.Bl -tag -width xxxxxxxx
.It Fl a
Automatically add any missing packages.
If a binary package exists in
.Pa ${PACKAGES}
it will be used in preference to building from source, unless the
.Fl b
or
.Fl s
options are given.
.It Fl B
Include the "Build version" (see option
.Fl b
.Xr pkg_info 1 )
of packages when determining if a package is up to date.
.It Fl b
Use binary packages.
If
.Fl s
is not set this allows
.Nm
to run without
.Ev PKGSRCDIR .
.It Fl C Ar conf
Use the
.Pa pkgchk.conf
file
.Sq Ar conf .
.It Fl D Ar tags
Add the comma separated list of tags to those checked when parsing
.Pa pkgchk.conf .
Also includes
.Ev PKGCHK_TAGS .
.It Fl f
Fetch all missing/mismatched packages found.
Can be used with
.Fl a
or
.Fl u
to perform the fetch before any building.
.It Fl g
Generate an initial
.Pa pkgchk.conf
file based upon the packages installed on the host machine.
.It Fl h
Brief help.
.It Fl k
Continue with further packages if errors are encountered.
.It Fl L Ar file
Redirect the output for all commands run into the logfile
.Pa file .
Should be specified as a full pathname.
On any error the tail end of the logfile will be displayed.
.It Fl l
List the filename for all binary packages (including best dependencies) based
on
.Pa pkgchk.conf .
Will abort if a binary package is missing.
This can be used (in conjunction with
.Fl U
and
.Fl D )
to determine what
packages would need to be copied to a remote machine to ensure it
was completely up to date.
The list is sorted so that dependencies
always come before packages which depend upon them.
.It Fl N
For each installed package, look if there is a newer version
noted in
.Pa ${PKGSRCDIR}/doc/TODO .
Good for finding packages to update.
.It Fl n
Display actions that would be taken, but do not change anything.
.It Fl P Ar path
Set the path to the binary packages.
Defaults to
.Ev PACKAGES
if
.Ev PKGSRCDIR
is available, or
.Dq Pa \&.
otherwise.
.It Fl p
Print list of package directories that will be checked, then exit.
.It Fl q
Do not display actions or take any action; only list information
about package version differences.
Useful for options that list information about package differences, such as
.Fl a
or
.Fl u .
.It Fl r
Recursively delete any mismatched packages found.
Use with care, this does not record which packages were installed
for later update.
.It Fl s
Building missing packages from source.
If UPDATE_TARGET=package is set in
.Pa /etc/mk.conf ,
then
.Nm
will automatically generate binary packages for later reuse.
.It Fl U Ar tags
Remove the comma separated list of tags from those checked when
parsing
.Pa pkgchk.conf .
Also includes
.Ev PKGCHK_NOTAGS .
Package directories can also be skipped by listing them under
.Fl U .
Passing
.Sq *
to
.Fl U
will result in all default tags being unset
.It Fl u
Automatically update any installed but out of date packages.
If a binary package exists in
.Ev PACKAGES
it will be used in preference to building from source, unless the
.Fl b
or
.Fl s
options are given.
.Pp
Note: If the update fails (particularly when building from source), the system
will be left with missing packages.
Once the error has been fixed, a second run will resume the update.
.It Fl v
Verbose - list the tags set when checking
.Pa pkgchk.conf ,
and all packages checked.
.El
.Ss Deprecated Options
.Bl -tag -width xxxxxxxx
.It Fl c
Check versions of packages specified in
.Pa pkgchk.conf .
This is a synonym for
.Nm
.Fl a q ,
and will be removed in a future version.
.It Fl i
Check versions of installed packages, ignoring
.Pa pkgchk.conf .
This is a synonym for
.Fl u q ,
and will be removed in a future version.
.El
.Sh FILE FORMAT
Anything after a
.Sq #
on a line is considered a comment.
.Pp
Each line in
.Pa pkgchk.conf
can either define a new tag or a package directory
(such as sysutils/skill), in each case followed by a list of tags.
.Ss New tag groups
Lines that define a new tag can be used to group tags to avoid
repeating the same set of tags for multiple packages.
For example:
.Dl mailserver      \= tll gta tycoon jeeves iris
would cause the mailserver tag to be set for any of the listed hosts.
Note that the tags after the
.Sq =
are parsed with the same set of tag
evaluation rules as those after package definitions (see later).
.Ss Package definition lines
Package directory lines are used to determine which packages are to be
installed, checking the tags against the current defined set.
.Ss Tag evaluation
Tags on package directory are checked against the current machine's set:
.Bl -bullet
.It
If a matched tag starts with a hyphen
.Sq - ,
the package is always excluded.
.It
Otherwise if any tags match the package will be included.
.It
A line without any tags matches all machines.
.It
An asterisk
.Sq *
matches any tag.
.It
If a tag starts with an
.Sq /
then it is checked for as a readable filename.
.It
Tags cannot contain a hyphen
.Sq -
or plus
.Sq + .
.It
Tags separated by spaces are treated as
.Dq or .
.Dq taga tagb
means if
.Em taga
or
.Em tagb
match the current machine.
.It
Tags separated by a plus are treated as
.Dq and .
.Dq taga+tagb
means if
.Em taga
and
.Em tagb
match the current machine.
.El
.Pp
The default set of tags used to determine which packages to match
in
.Pa pkgchk.conf
are equivalent to the output of the following with
any spaces converted to hyphens (-): hostname -s, hostname, uname
-srm, uname -sr, uname -sm, uname -s, uname -r, uname -m.
If
.Pa /usr/X11R6/lib/libX11.so
or
.Pa /usr/X11R6/lib/libX11.a
is present,
.Em x11
is added to the list of tags.
Tags should not contain the - or + characters.
To see tags for the current machine, run
.Nm
with the
.Fl v
option.
.Sh ENVIRONMENT
.Nm
uses the following environment variables.
.Bl -tag -width xxxx
.It Ev MAKECONF
Path to
.Pa mk.conf .
Defaults to
.Pa @MAKECONF@ , @PREFIX@/etc/mk.conf ,
or
.Pa /etc/mk.conf .
.It Ev PKGSRCDIR
Base of pkgsrc tree.
If not set in the environment, then this variable is read from
.Pa ${MAKECONF} .
If it is still not set, and if the current working directory
appears to be inside a pkgsrc tree, then this variable
is set to the base of that pkgsrc tree.
Finally, if
.Pa /usr/pkgsrc
appears to contain a pkgsrc tree, then that is used as a last resort.
.It Ev PKG_DBDIR
pkgsrc database directory.
If not set in environment then read from
.Pa ${MAKECONF} .
Defaults to
.Pa @PKG_DBDIR@ .
.It Ev PACKAGES
Location of binary packages.
If not set in environment then read from
.Pa /etc/mk.conf .
Defaults to
.Pa ${PKGSRCDIR}/packages .
.Pp
Unless in a completely homogeneous environment (every machine running
exactly the same OS version and architecture) setting
.Ev ${PACKAGES}
in
.Pa /etc/mk.conf
to a value such as
.Bd -literal
${PKGSRCDIR}/packages/${LOWER_OPSYS}-${OS_VERSION}-${MACHINE_ARCH}
.Ed
.Pp
is strongly recommended.
If
.Em cpuflags
(devel/cpuflags) is being used to optimally target individual CPU types,
then
.Ev ${CPU_DIR}
should be appended to
.Ev ${PACKAGES} .
.It Ev PKGCHK_CONF
Pathname to pkg_chk configuration file.
If not set in environment then read from
.Pa /etc/mk.conf .
Defaults to
.Pa ${PKGSRCDIR}/pkgchk.conf .
.It Ev PKGCHK_UPDATE_CONF
Pathname to temporary list of installed packages used when updating.
If not set in environment then read from
.Pa /etc/mk.conf .
Defaults to
.Pa ${PKGSRCDIR}/pkgchk_update-$(hostname).conf .
Note, if pkgsrc is being
shared across multiple machines which may be updating at the same time then
it is important this file does not overlap between machines.
.It Ev PKGCHK_TAGS
Additional tags to add when parsing
.Pa pkgchk.conf .
.It Ev PKGCHK_NOTAGS
Additional tags to unset when parsing
.Pa pkgchk.conf .

.Sh BUGS
When used against binary packages,
.Nm
does not handle the directory containing multiple versions of the same package.
