Comparing values of two consequent lines

Hi,

I have a textfile with lot of lines.
These lines have the following format

<command> a-<name of parameter> <value>
<command> b-<name of parameter> <value>

where
<command> is a command identical for all lines
<name of parameter> are different commands.
<value> is a numeric value.

The commands are paired. A certain command exist in
the form 'a-command' and 'b-command'.

The lines are sorted in way that lines with a certain
command ("a-" and "b-" form) are always paired and
grouped together.

I want to check, whether all paired lines have attached
the same value.

There are way too many lines to do this manually and doing
so would be much too error prone.

Can this done with vim automagically and how?
Or: Is there already a unix tool (I am on Linux), which
could do this check?

Thanks a lot for any help in advance!
Cheers!
Meino
