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.

Code:
:1,$s/-I/\n/g

Thanks Padow,

Unfortunately, using your syntax causes each instance of " -I" to be replace with "^@" as in:

^@/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

Any other ideas?

Found the fix (aka: solution)

Thanks (again) to Padow, a slight change to his syntax solved the problem. Here is the syntax that worked:

:1,$s/ -I/\r/g

Note that I included a space in the seach-for text " -I". This allowed for the extra space to be removed so each line starts at the beginning.

Cheers!

Code:
you can replace 1,$ by % - indicates replace on all lines 
%s/-I/\r/g
