  To show all installed packages you can use the "dpkg" command, and
 then filter the list via grep to those that are installed.  (And not
 removed/purged).  To do this run:

skx@itchy:~$ dpkg --list |grep ^ii

  You might find the package name is truncated, so can fix this
 by running:

skx@itchy:~$ COLUMNS=200 dpkg --list |grep ^ii

  Finally if you just want to see the *name* of the package you can
 use awk to print that out alone.  This stops you from seeing the
 one-line package description too:

skx@itchy:~$ COLUMNS=200 dpkg --list |grep ^ii | awk '{print $2}'

  If you wish this list to be in a file just use redirection:

skx@itchy:~$ COLUMNS=200 dpkg --list |grep ^ii | awk '{print $2}' > list.txt
