I just added a ppa like so:
sudo add-apt-repository ppa:stebbins/handbrake-releases
Now, how do I get to see which packages this PPA contains?
I'm sure there is many ways to do this - since you have added the PPA, the package details exist in /var/lib/apt/lists
Thus for your example ppa:stebbins/handbrake-releases
substitute / for an _ and remove the prefix ppa: i.e. stebbins_handbrake-releases
Then just use this repositoryname in the following command line entry:
cat /var/lib/apt/lists/ppa.launchpad.net_[repositoryname]_*_Packages | grep "Package:" | sort | uniq
i.e.
cat /var/lib/apt/lists/ppa.launchpad.net_stebbins_handbrake-releases_*_Packages | grep "Package:" | sort | uniq
On newer versions of Debian the Packages file is LZ4 compressed, so you'll need to apt-get install liblz4-tool and then insert an lz4cat step into your pipeline to decompress it:
lz4cat /var/lib/apt/lists/ppa.launchpad.net_stebbins_handbrake-releases_*_Packages | grep "Package:" | sort | uniq
This will list the contents:
Package: handbrake-cli
Package: handbrake-gtk
