NAME

       germinate-pkg-diff — compare seeds against currently installed packages

SYNOPSIS

       germinate-pkg-diff [-l file] [-m {i|r|d}] [-a arch] [seeds]

DESCRIPTION

       germinate-pkg-diff  compares  the  expansion  of  a  list  of  seed  packages against the set of packages
       installed on the current system.  When constructing seeds for a software distribution, it can be used  to
       iteratively find packages installed on developers' systems that should be included in the seeds.

       A  list of seeds against which to compare may be supplied as non-option arguments.  Seeds from which they
       inherit will be added automatically.  The default is ‘desktop’.

OPTIONS

       -l, --list file
             Read the list of currently installed packages from file.  The default is to read the output of dpkg
             --get-selections, and any supplied file should be in the same format.

       -m, --mode {i|r|d}
             Set the output mode as follows:

             i     Show the dpkg selections needed to install just these seeds.   List  unseeded  but  installed
                   files as “deinstall”, and seeded but uninstalled files as “install”.

             r     List  unseeded  but  installed  files  as  “install”,  and  seeded  but  uninstalled files as
                   “deinstall”.

             d     Show the differences between the packages specified by the seeds and the  list  of  installed
                   packages, in a somewhat diff-like format.

       -S, --seed-source source,...
             Fetch       seeds       from       the       specified      sources.       The      default      is
             http://people.canonical.com/~ubuntu-archive/seeds/.

       -s, --seed-dist dist
             Fetch seeds for distribution dist.  The default is ubuntu.bionic.

       -d, --dist dist,...
             Operate on the specified distributions.  The default is bionic.  Listing multiple distributions may
             be useful, for example, when examining both a released distribution and its security updates.

       -a, --arch arch
             Operate on architecture arch.  The default is i386.

BUGS

       --mode r is useless as dpkg --set-selections input.
