vi Search for text, Replace with <CR> or control character.
Greetings,
Using vi, how can I change the following text:
-I/myviews/nexus_7400rel/vobs/nexus/platforms/97400/include -I/myviews/nexus_7400rel/vobs/nexus/modules/i2c/7400/include -I/myviews/nexus_7400rel/vobs/nexus/modules/surface/7400/include
Into this:
/myviews/nexus_7400rel/vobs/nexus/platforms/97400/include
/myviews/nexus_7400rel/vobs/nexus/modules/i2c/7400/include
/myviews/nexus_7400rel/vobs/nexus/modules/surface/7400/include
The first text is a contiguous string with spaces and "-I" separating the lines of include paths (yes, this is from a "C" makefile output).
I want to search for all the occurances of " -I", and replace with a carriage return (or linefeed) using vi. This is for vi on a Linux system.
The search portion is easy: :g/ -I/s// (what goes here?)/g
It's the "what goes here?" part that I need help with.
Any answers or alternative solutions would be greatly appreciated.
