bpkg-pkg-unpack – unpack package archive


bpkg pkg-unpack [options] (pkg[/ver] | --existing|-e dir)


If only the package name is specified, then the pkg-unpack command unpacks the archive for the previously fetched (bpkg-pkg-fetch(1)) package. The resulting package state is unpacked (bpkg-pkg-status(1)).

If the package version is also specified, then the (source) directory from one of the directory-based repositories (bpkg-rep-add(1)) is used in place, without copying it into the configuration directory. Such a package is called external.

If the --existing|-e option is used, then instead of the package name, pkg-unpack expects a local path to an existing package directory. In this case, bpkg will use the (source) directory in place, the same as for packages from directory-based repositories. Also, unless the --purge|-p option is specified, bpkg will not attempt to remove this directory when the package is later purged with the bpkg-pkg-purge(1) command. Such a package is also external.

If --existing|-e is specified together with the --replace|-r option, then pkg-unpack will replace the archive and/or source directory of a package that is already in the unpacked or fetched state.

An external package triggers several changes in semantics compared to a normal package: The package (output) directory inside the configuration is called just pkg rather than pkg-ver. It is also assumed that the packaging information (package manifest and lockfile) for such packages may change without incrementing the package version (for example, during development). To support this, bpkg implements the package iteration mechanism which may result in iteration numbers to be shown as part of the package version, for example, 1.2.3#1 (see Package Version).


Treat the argument as an existing package directory path rather than the package name to unpack.
Remove the existing package directory when the package is purged.
Replace the source directory if the package is already unpacked or fetched. Can only be specified with an external package.
--directory|-d dir
Assume configuration is in dir rather than in the current working directory.
