Shell Programming and Scripting

Hi ,

i am writing a script in which i am using following command to grep some string and then storing it's output to v, as like below :-
v=$(awk -F, '{ if ( $NF ~ /DEV/ ) print $0 "_BLD01";else print $0 "_RC01" }' mytest)

Here i am facing following issues:-

1. it is searcing DEV in the file, but i want to search DEV only if it has DEV at the end of any string. and in this case It is finding all the DEV words in the string.
for exp :- DEVinder.sh ( i want it will search only if there is DEV at the end like inder.sh_DEV) and ignore it has DEV oter than last.

Code:

 awk  '/DEV$/{ print $0 "_BLD01"}
       !/DEV$/{print $0 "_RC01" }' mytest
