Another question about find.  I looked at the gnome tool and tried to 
simulate what it is doing.  I can't use it directly because it won't
do sed.  Basically I want to find all files with a string (except binary)
and change it.  let STR be the string I am looking for.  NEW is new string.
I am doing

TFIL=/usr/tmp/dummy$$.txt
find . -type f | while read fil
do
     grep "$STR" $fil > $TFIL
     [ $? -eq 0 ] || continue      ## does not match

     if [ "$(cat $TFIL)" = "Binary file $fil matches" ]
     then
          continue    # Don't operate on binary files
     fi

     sed -i "s/$STR/$NEW/g" $fil
done

(I will have to do something with sed in case there is "/" in the string)

Problem is, the grep redefines my stdin so it no longer comes from
the list of files that "find" found, and it then terminates after finding
the first file.

Anyway to "push" stdin on the stack or something before the grep,
and "pop" it again afterwards, so it goes back to the list of files found?
