.Sh NAME
.Nm xbps-install
.Nd XBPS utility to (re)install and update packages
.Sh SYNOPSYS
.Nm xbps-install
.Op OPTIONS
.Op PKG...
.Sh DESCRIPTION
The
.Nm
utility installs, reinstalls, downgrades and updates packages in the target root directory.
The argument
.Ar PKG
is a package expression, which is explained in the
.Em PACKAGE EXPRESSION
section. If package is installed, it will be updated to the version available in repositories
matching the
.Em PACKAGE EXPRESSION .
Otherwise it will be installed, or reinstalled/downgraded if
.Fl f , Fl -force
option is set.
.Sh PACKAGE EXPRESSION
A package expression is a form to match a pattern; currently xbps
supports 3 ways to specify them:
.Bl -dash
.It
by package name, i.e:
.Dq Sy foo .
The package with the greatest version available in all repositories will be choosen.
.It
by exact package name and version, i.e:
.Dq Sy foo-1.0_1 .
The first package matching expression in a repository will be choosen.
.It
by specifying a package name and version separated by any of the following version comparators:
.Bl -item -width xx -compact
.Pp
.It
.Sy <
less than
.It
.Sy >
greater than
.It
.Sy <=
less or equal than
.It
.Sy >=
greater or equal than
.Pp
Example:
.Dq Sy foo>=2.0 .
The first package matching expression in a repository will be choosen.
.Sh OPTIONS
.Bl -tag -width -x
.It Fl A, Fl -automatic
Enables automatic installation mode, i.e. package will be treated as orphan
if no package is depending on it directly.
.It Fl C, Fl -config Ar file
Specifies a full path to the XBPS configuration file.
.It Fl c, Fl -cachedir Ar dir
Specifies a full path to the cache directory, where binary packages are stored.
.It Fl d, Fl -debug
Enables extra debugging shown to stderr.
.It Fl f, Fl -force
Force downgrade installation (if package version in repos is less than installed version),
or reinstallation (if package version in repos is the same) to the target
.Ar PKG ,
overwriting regular package files and symlinks (if they have been modified) but
.Em preserving configuration files .
If
.Fl f
is specified twice,
.Em configuration files will also be overwritten .
.It Fl h, Fl -help
Show the help usage.
.It Fl n, Fl -dry-run
Dry-run mode. Show what actions would be done but don't do anything.
.It Fl R, Fl -repository=uri
Repository to be added to the top of the list. This option can be specified multiple times.
.It Fl r, Fl -rootdir Ar dir
Specifies a full path for the target root directory.
.It Fl S, Fl -sync
Synchronize remote repository index files.
.It Fl u, Fl -update
Performs a full system upgrade: all installed packages will be updated to the greatest
versions that were found in repositories.
.It Fl v, Fl -verbose
Enables verbose messages.
.It Fl y, Fl -yes
Assume yes to all questions and avoid interactive questions.
.It Fl V, Fl -version
Shows the XBPS version.
.Sh ENVIRONMENT
.Bl -tag -width XBPS_TARGET_ARCH
.It Sy XBPS_ARCH
Overrides
.Xr uname 2
machine result with this value. Useful to install packages with a fake
architecture.
.It Sy XBPS_TARGET_ARCH
Sets the target architecture to this value. This variable differs from
.Sy XBPS_ARCH
in that it allows you to install packages partially, because
configuration phase is skipped (the target binaries might not be compatible with
the native architecture).
.Sh FILES
.Bl -tag -width /var/db/xbps/.<pkgname>.plist
.It Ar /etc/xbps/xbps.conf
Default configuration file.
.It Ar /var/db/xbps/.<pkgname>.plist
Package metadata properties.
.It Ar /var/db/xbps/pkgdb-0.21.plist
Default package database (0.21 format). Keeps track of installed packages and properties.
.It Ar /var/cache/xbps
Default cache directory to store downloaded binary packages.
