Tell me more ×  I want to find packages whose names contains
characters in a specified search string. Something similar to
apt-cache search, but I also want the output to show whether the
package is installed on my system by marking with a flag ii
(installed) or un (not installed).  $ dpkg -l *skype*  ||/ Name
Version            Description un  skype              <none>
(no description available) un  skype-common       <none>
(no description available) un  skype-mid          <none>
(no description available)  So Ubuntu finds skype in its
software center and it passes the flag un, indicating its not
installed on my system.  Well, actually it is installed on my
system:  $ apt-cache policy skype  So why was the un flag
associated with skype in the above example?  In fact, whenever I
use the dpkg command, it thinks the package is not installed:
dpkg -L skype Package `skype' is not installed. share|improve
