NAME
pk4 - make available the Debian source package producing the specified package
SYNOPSIS
pk4 [options] package...
DESCRIPTION
pk4 resolves the specified argument(s) as either:
1. the name of a Debian binary package, and selects its Debian source package.
2. the name of a Debian source package, and selects it.
3. or a file path, and selects the Debian source package of the owning package.
The source package version is either the installed version (if any) or the installation candidate, as per
apt-cache policy.
Then, pk4 downloads the entire selected source package (every file referenced by — and including — its
.dsc file) and prints the output directory path.
OPTIONS
-allow_unauthenticated
Whether to allow unauthenticated source packages, i.e. disable signature checking.
-bin Restrict search to binary packages only.
-complete
Whether to return shell completions. Should usually be set by shell completion functions only.
-dest string
Directory in which to store source packages (default ~/.cache/pk4).
-file Interpret the argument as a file name and operate on the package providing the file.
-resolve_only
Resolve the provided arguments to source package and source package version, then print them to
stdout in %s\t%s\n format and exit.
-shell string
Which shell to start in the output directory after downloading the source (default $SHELL)
-src Restrict search to source packages only.
-verbose
Whether to print messages to stderr.
-version string
Use the specified source package version (default: installed package version, or latest known if
not installed).
EXAMPLES
# Avail the current Linux kernel sources:
pk4 -src linux
# Avail the sources which produced Debian binary package libbz2-1.0
pk4 libbz2-1.0
# Avail the sources of whichever package currently provides vi:
pk4 -file $(which vi)
# Fetch the i3 source, apply a bugfix, rebuild and replace installed packages:
pk4 i3
patch -p1 < /tmp/myfix.patch
pk4-replace
# Avail all debhelper build system implementations:
pk4 -allow_unauthenticated $(grep '^dh-*' /var/cache/pk4/completion.both.txt)
# Grep through their sources:
grep -r option ~/.cache/pk4/dh-*
CONFIGURATION FILE
The following attributes can be configured in ~/.config/pk4/pk4.deb822: Disk-Usage-Limit bytes Example: Disk-Usage-Limit: 2GiB
HOOKS
The following hooks can be configured:
after-download
after-download hooks are run after the package was successfully downloaded. Examples:
# Automatically create a git repository for each package:
mkdir -p ~/.config/pk4/hooks-enabled/after-download/
ln -s /usr/share/pk4/hooks-available/after-download/git-init \
~/.config/pk4/hooks-enabled/after-download/
unpack unpack hooks replace the unpack phase: as soon as one or more unpack hooks are found, pk4 will run
them instead of running dpkg-source -x. Examples:
# Unpack source into a new git-buildpackage repository:
apt install git-buildpackage
mkdir -p ~/.config/pk4/hooks-enabled/unpack/
ln -s /usr/share/pk4/hooks-available/unpack/gbp \
~/.config/pk4/hooks-enabled/unpack/
