Now,
There are many tools which will give you command line editing ,
Resource hacker : Free and good one,
it provides scripting and saving resources go through help file where u get hell lot of examples about that ,
by the way u only asked for cheap OR free utilities ,
but there are several tolls which can perform efficiently (not free one)
if u want some more util call me ...
and yes most of the paying resource editor tools provide command line editing free.....means u can download trail and go for cmd line editor absolutely free....
