One key point is that the output should include every package returned
by
"apt-cache search <SearchTerm>"
& show whether or not they are installed.
===== Example showing the concept, using package "parted":
1) First, here are all the packages apt-cache returns:
# apt-cache search parted | sort
drobo-utils - manage data robotics storage units (drobos)
fatresize - FAT16/FAT32 filesystem resizer
gnu-fdisk - Linux fdisk replacement based on libparted
gparted - GNOME partition editor
kvpm - LVM frontend for KDE
libparted0debian1-dbg - The GNU Parted disk partitioning library debug
development files
libparted0debian1 - The GNU Parted disk partitioning shared library
libparted0-dev - The GNU Parted disk partitioning library development
files
libparted0-i18n - The GNU Parted disk partitioning library i18n support
libparted0 - The GNU Parted disk partitioning shared library (old name)
parted-doc - The GNU Parted disk partition resizing program
documentation
parted - The GNU Parted disk partition resizing program
partitionmanager - A partition management utility
python-parted-dbg - Python interface for libparted - Debugging symbols
python-parted - Python interface for libparted
2) But "dpkg -l" only shows some of them:
dpkg -l | grep parted
ii gparted 0.5.1-1ubuntu2
GNOME partition editor
ii libparted0 2.2-5ubuntu5
The GNU Parted disk partitioning shared libr
ii libparted0debian1 2.2-5ubuntu5
The GNU Parted disk partitioning shared libr
ii parted 2.2-5ubuntu5
The GNU Parted disk partition resizing progr

ii parted 2.2-5ubuntu5
The GNU Parted disk partition resizing program
un parted-doc <none>
(no description available)
un parted1.6 <none>
(no description available)
}
3a) I'd like to get an output list including all the packages from step
1 above,
3b) Showing the package name, & its installed status (ii, un, etc) like
from step 2.
Note: One way might be to:
1) Do the apt-cache search <packagename>
2) For each line
2a) Pull out the package name
2b) Write an apt-cache search for that name only to a temp file
3) Do the dpkg -l 's from the file
3b) & remove from the output all the dpkg heading info, leaving only the
package status lines.
Can you get that mashup? Thanks :)
========== RESULTS SO FAR: ==========
===== From tomh0665
# aptitude -F "%c%a %p %v %d" search '?narrow(?installed,parted)'
i gparted
0.5.1-1ubu GNOME partition editor
i libparted0
2.2-5ubunt The GNU Parted disk partitioning shared library (old name)
i libparted0debian1
2.2-5ubunt The GNU Parted disk partitioning shared library
i parted

: The good thing here is this shows the package installed status.
: But it is missing many of the packages shown by "apt-cache search
parted", many of which are probably not installed.
===== From aaron.toponce
alias apt-search="aptitude search"
# dpkg -l $(apt-search parted |grep ^i|awk '{print $2}'|tr '\n' ' ')

No packages found matching A.
No packages found matching A.
: The good result here is that this shows the dpkg -l, which can show
uninstalled or failed match packages.
: But it doesn't yet get all the packages.

Aaron & Tom - can you mash this up a little better? Thanks :)
