first, syntax for awk is wrong, you want something like:

    awk ' {if (substr($1,9,1) == "w" ) print $8 > "test.out" } '
        ^ ^   ^               ^^ ^ ^ ^       ^^   ^        ^ ^ ^
        1 2   3                4 5 5 3       6    5        5 2 1

1) a single quote needs to surround the <format> of awk
2) currly brackets are also needed for <format>
3) if stmt's condition needs to be surrounded by parens (sp?)
4) equallity is tested using double =
5) all text must be enclosed in quotes, or it is assumed to be a variable
6) you may or may not want to add this to get only the file name

second, find's -ls does not produce the same output as 'ls -al'. It
produces something like:

 9601    1 drwxr-xr-x  3 weimer   staff         512 Nov 13 11:42 file_name

so the command you want to use would be:

find / -user root -ls | awk '{if (substr($3,9,1)=="w") print $11 > "test.out"}'

Hope this helps.

P.S. you might also want to find file owned by root that are group writeable
and are part of some universal group (like 'user').
