From: Todd A. Jacobs on 21 Jun 2010 14:10 Is there some functionality in apt-cache or aptitude for displaying recommended files, other than having to visually parse the output of "apt-cache show"? Basically, I'd just like to get a list of recommended packages from a list of installed or prospective packages without having to use the aptitude GUI. -- "Oh, look: rocks!" -- Doctor Who, "Destiny of the Daleks" -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Maybe grep-dctrl (package dctrl-tools) can help with this.

If you can handle the *curses interface of aptitude do: 1. Execute 'aptitude'. 2. Press Ctrl+T. 3. Use left/right to navigate to "Views". 4. Use up/down to navigate to "Audit Recommendations". This shows anything recommended but not installed. By using up/down to highlight a particular recommendation, you can see why it is recommended in the bottom pane. Aptitude does this (mostly) with a package limit, and we can easily see what it is. Press 'l'. This allows you to edit the package limit, but it shows the current one so we can note it. "!~v!~i~RBrecommends:~i" With this magic string, we can get much of this data from the command line. Simply issuing (aptitude search '!~v!~i~RBrecommends:~i') from the shell will basically give us the data in the top frame. For any particular package in that list (e.g. policykit-gnome), you can also determine why it would be recommended from the command line. Simply issuing (aptitude why '~i' 'policykit-gnome') will give the "most installed, strongest, tightest, shortest" reason to install that package, which should be a recommendation. Try (aptitude -v why '~i' 'policykit-gnome') for other interesting results. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss(a)iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

In dselect the search feature is the same '/', once you enter your search if you keep pressing the '/' key you cycle through all the matches to the search string. In aptitude the '/' key brings up the search dialog again and I have to press three keys to continues the search, '/' to open search dialog, 'tab' key to select the 'OK' or ''Cancel' button, then the 'enter' key to find , repeat. I am wondering if I am missing a feature of aptitude, or if I just need to learn the new way. ? -- Peace, Greg -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
