I already use apt-get for most of my package management. Yet, there are times when I occasionally need to use Synaptic to do certain things. I would like to learn the equivalent commands for doing the following things in Synaptic:
- Check a package's dependencies / dependent packages. (This can be done in Synaptic by viewing the properties of a package).
- Browse available packages
- Search (in package names as well as the details/descriptions) for some key. (The search function at the top of synaptic)
- Check if a package is installed or not
Also, is there a way to find packages that are no longer necessary (e.g. a package no longer in use because I removed a dependency). I have a feeling my system is terribly bloated because I removed certain programs and not all the dependencies went with them.
