hey guys , my input look like this: 
" 
-IE:\david\nbssbts\btsc\bld -IE:\david\nbsscis\dcsapp\bld \
--cxx_include_directory C:\Green\scxx -IC:\Green\scxx \
-IC:\Green\68000\include -IC:\Green\ansi \
"

I need to capture the -I only and make it look like this : 
"
-IE:\david\nbssbts\btsc\bld 
-IE:\david\nbsscis\dcsapp\bld 
-IC:\Green\scxx 
-IC:\Green\68000\include 
-IC:\Green\ansi
"

Now I am able to capture the -I but they don't appear in different line also the main problem is it will capture the "--cxx_include_directory" which I don't need.

my code is 

if (index ($_, "-I") == 1){
    { print OUTFILE substr ($_, 0, rindex ($_, "\\")), "\n"; }
}
