Removing duplicate RPMS.

Got the script mainly with google search on the <a href="http://linux.derkeiler.com/Mailing-Lists/Fedora/2006-12/msg04156.html">link.

Nice trick..

Get the list of rpms with just the names
rpm -qa –queryformat &#8217;%{name}\n&#8217; > pkglist

Get the non-uniques list.
sort -g pkglist | uniq -d > duplicates

Get the versions of the duplicate files:
for pkg in `cat duplicates`; do
rpm -q $pkg » removelist
done

Now keep the rpms that you want to delete in the removelist

6) Something that is difficult to find on the net is : how to create a numbered list in vi/vim? Simple, we will use macro's
To do this:
a> type number and terminatory ex: 1)
b> start recording using qa  . This will record the macro in a.
c> yank the line with yy
d> goto next line
e> press a to increment the number
f> End the macro recording with q
g> Play the macro with numner of times to repeat the actions. Example press 11@a
7) For repeating the last command you can use
8) You can put your vim settings in ~/vimrc and this can containg things like "set nu" and any other configuration.
9) Adding date in vi : :r! date
10) There is a variant of vi known as elvis which is quite nice
11) Similarly for viewing binary file there is a variant called bvi
