Dear all expert,

How can I find a word in all files under / ? Please be informed that it contains files or folders under /  so "more /* | grep (word)" is not workable.

Thanks

Gary

If you are using gnu grep, use the -r switch to recursively search.
      grep -r word /*

Otherwise use find:
      find / -type f | xargs grep word

If you don't have xargs, use find -exec
      find / -type f -exec grep word {} \;

Brettt -
find / -type f -exec grep word {} /dev/null \;
will also give you the filename  ;-)

grep -l will give the file name instead of the matched lines.
