Hello folks,

I need some help in substitutions either using sed , awk or vi for the following problem.

I have the following lines in a file say xyz.file

END EN
PIN CLK
DIRECTION INPUT ;
PORT
LAYER VIA10 ;
RECT 0.xyz 0.807 0.5 0.857 ;
LAYER M02 ;
RECT 0.078 0.8 0.349 0.8 ;
END
END CLK
PIN VDD
DIRECTION INPUT ; --> change INPUT TO INOUT
USE POWER ;
PORT
LAYER VIA10 ;
RECT 0.820 1

I want to change the "DIRECTION INPUT" to "DIRECTION INOUT" only after the strings "PIN VDD" or " PIN VSS"

How can i accomplish this?

Appreciate your inputs on this.

Thanks!

dont bother i was able to do using sed.

sed '/PIN VDD /{n;s/INPUT/INOUT/ ;}' xyz.file > test_std.file

thanks!
