How I can find actual using of package?

Question

I need to find actual process or dependence on other library in running system for package by name.

How I can realize it?

Answer 1

I would suggest using Aptitude.

Aptitude is a TUI (Terminal User Interface) application managing program. It runs in a terminal but it is pretty intuitive to use anyways.

Install aptitude by using:

sudo apt-get install aptitude

in a terminal.
Run aptitude with:

aptitude

You can open up a terminal with CTRL+ALT+T

After you are in aptitude, you can use the / key to search for a package. If it isn't found the first time you search for it, you can use the / key and search for it again to find the next match.
After you have found the package that you want info on, press the enter key. That will bring up info on a package. You can navigate through it by using the up and down arrow keys.
