When doing a
find . -type f -exec grep "somthing" {} \;
then I get an error message
"find: unrecognized: -exec"
Is the find command different on ash?
Documentation says that it is the same.

The N900 comes with busybox. Busybox doesn't use the GNU coreutils utilities/commands instead it has watered downed versions with less features. BASH vs ASH is mostly syntax related.
Install this: http://maemo.org/packages/view/coreutils-gnu/
Or simply compile coreutils in scratchbox yourself and copy over the binary find command.
Woops find is not part of coreutils but instead findutils.

Thanks.
Does "findutils-gnu v4.4.2-1maemo7"
http://maemo.org/downloads/product/M...findutils-gnu/
also do the trick?

That's probably why they put xargs in findutils.
busybox find + xargs = good

Xargs is nice.. but... Shell is pretty versatile
Remember to enclose "$file" in double-quotes..
Code:
find / -some-options | while IFS="" read file ; do echo "Found file: $file" ; done

I think you'll find it's not, the Maemo busybox is configured with support for find -print0 but not xargs -0 :-(
