In Ubuntu, new applications are usually available as deb packages. Although Ubuntu comes packaged with gui package management tools like synaptic, the command line provides a much faster way. Read on to know how to manage deb packages in Ubuntu from the command line using apt-cache.

'apt-cache search' - Used to search for repositories.

If you want to install a package and if you want to search for it i.e. check whether it is a valid package, you can use apt-cache search. For example

 apt-cache 'package-name'

Suppose you want to search for the package skype

 apt-cache search skype  
pidgin-skype - Skype plugin for libpurple messengers
pidgin-skype-dbg - Skype plugin for libpurple messengers (debug symbols)
earcandy - Sound level manager for PulseAudio
skype - Skype 

'apt-cache search' - Used to search package using package description.

That is, if you want to install phpmyadmin, you can search for it in'apt-cache search php'. This will list all the packages relating to php, including phpmyadmin

'apt-cache show 'package-name' : To display the basic information about a package.'

For example : You can try this by going through the command 'apt-cache show skype'

This will list all the details the package skype

You will get something like this

Package: skype

Linux is the epitome of the FLOSS model. Technical Solution Linux installation Leave a reply Your email address will not be published. Required fields are marked * Dewey J. Corl (not verified) access_time 25 May 2020 - 08:47 Linux is not ready for the general public! (I am a Ubuntu user). For proof, 1. try to simply print labels on a Dymo label printer. It takes a LOT of work to get to the ease of label printing already available in Windows and Mac. 2. try syncing a modern Palm based PDA. Yes, jpilot and others will sync the main data, but pictures and midi files do not get transferred without a lot of extra setup. These are examples of applications that are not ready for the general public. Since an operating system only supports applications, Linux is not ready to be a common desktop for the general public. While we are waiting for the applications to catch up, keep up the good work!! Anoop John (not verified) access_time 25 May 2020 - 08:47 Dewey Yes you may be right. But these are not applications that a common man would use. A common man would use one of these applications - Internet browser, Chat Client, Email Client, Document Writer, Presentation Creator, Spreadsheet Editor, Movie Viewer, Music Player, CD/DVD Writer. Both examples you cited are more specific applications that only a small percentage of the whole population uses. It will take time before those hardware vendors identify the need from their perspective to address the Linux community.

I am getting immersed in the LINUX and seeing the versatility. To my surprise, I am able to read one of my old backup CD(wherein lot of my valuable file exist) done in DIRECT CD wizard (a custom cd writing software of Easy Cd creator in WIN98) which could not be read in XP. Installation of old version of easycd creator/direct cd program was not possible in XP. I thought that possible i lost all data. Very pleasant start! Srikanth N. S. (not verified) access_time 25 May 2020 - 08:47 Hi Anoop, My friend is thrilled with Ubuntu. One of his grouses with windows was that after OS installation, everything else is to be installed separately which is a real headache. WHereas if u install Linux, everything is installed as a package and he is thrilled to bits! Let linux installation spread in Trivandrum and your service in this direction is highly appreciated. Kepp up the good work Regards. PDA Freak (not verified) access_time 25 May 2020 - 08:47 Is it possible to install linux on a packardbell notebook ?
