    My folder of files is 'c:\vehicles'. The file I want to write to is 'vehicles.txt' and located in 'c:\'. I tried the following code work for what you suggested. I know I've written it wrong. What should I do to correct it? 

    C:\vehicles $ ls -A | xargs head -qn 30 | perl -Mstrict -wne  'if( $ +
+_ =~ /(make)|(model)|(year)/ ) { print "$_"; }' > vehicles.txt
grep -rE "(make|model|year)" c:

      What is $ +_? Do you mean $_?

      If so, then you can omit it and use just: 'if( /(make)|(model)|(year)/ ) { print "$_"; }'.

      Whether that fixes all your problems I doubt; but its one less to deal with.
