.Dt PKGCHK 1
.Sh NAME
.Nm pkg_chk
.Nd check, and optionally update, installed packages
.Sh SYNOPSIS
.Nm
.Op Fl abcfhiknrsuvB
.Op Fl C Ar conf
.Op Fl D Ar tags
.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.
.Pp
.Sy Options
.Bl -tag -width xxxxxxxx
.It Fl B
Check the "Build version" (see option -b of pkg_info(1)) of packages.
.It Fl C Ar conf
Use the pkgchk.conf file
.Sq Ar conf .
.It Fl D Ar tags
Add the comma separated list of tags to those checked when parsing
pkgchk.conf. Also includes
.Ev PKGCHK_TAGS .
.It Fl U Ar tags
Remove the comma separated list of tags from those checked when
parsing pkgchk.conf. Also includes
.Ev PKGCHK_NOTAGS .
Package directories can also be skipped by listing them under
.Fl U
.It Fl a
Automatically add any missing 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.
.It Fl b
Limit additions or updates to using binary packages. If
DEPENDS_TARGET=package
is set in
.Pa /etc/mk.conf ,
then
.Nm
will automatically generate binary packages for later reuse.
.It Fl c
Check versions of packages specified in pkgchk.conf.
.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, or with
.Fl c
or
.Fl i
to just fetch missing/mismatches packages.
.It Fl h
Brief help.
.It Fl i
Check versions of installed packages, ignoring pkgchk.conf.
.It Fl k
Continue with further packages if errors are encountered.
.It Fl n
Display actions that would be taken, but do not change anything.
.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
Limit additions or updates to building from source.
.It Fl u
Automatically update any missing packages. If a binary package exists
in 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 packaged.
.It Fl v
Verbose - list the tags set when checking pkgchk.conf, and all packages checked.
.El
.Sh FILE FORMAT
Each non comment line in pkgsrc.conf should contain a package
directory (such as sysutils/skill) followed by an optional list of
tags. Tags are checked against the current machine's set:
.Bl -bullet
.It
If a matched tag starts with a hyphen '-', 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
.Em *
matches any tag.
.It
Tags cannot contain a hypen '-' or plus '+'.
.It
Tags separated by spaces are treated as 'or'. 'taga tagb' means if
.Em tag_a
or
.Em tag_b
match the current machine.
.It
Tags separated by a plus are treated as 'and'. 'taga+tagb' means if
.Em tag_a
and
.Em tag_b
match the current machine.
.El
.Pp
The default set of tags used to determine which packages to match in
pkgsrc.conf are equivalent to the output of the following with any spaces
converted to hypens (-): 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 PKGSRCDIR
Base of pkgsrc tree. If not set in environment then read from
.Pa /etc/mk.conf .
Defaults to
.Pa /usr/pkgsrc
.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_TAGS
Additional tags to add when parsing pkgchk.conf.
.It Ev PKGCHK_NOTAGS
Additional tags to unset when parsing pkgchk.conf.
.El
.Sh EXAMPLES
Sample pkgchk.conf file:
.Bd -literal
# Must install before others

.Sh BUGS
Updating packages on which other packages depend can currently only be done
via source (not binary packages).
.Pp
If both package
.Em a
and package
.Em b
are to be updated, and
.Em a
depends on
.Em b ,
.Nm
will correctly skip the update of
.Em a .
However, if
.Em a
depends on
.Em b
and
.Em c ,
and all three are marked for update,
.Nm
will update
.Em b
and
.Em c
in two separate passes, resulting in unnecessary rebuilding of
.Em a
(and potentially other packages).
