How to escape "find" result

[Try KDE <trykde@rogers.com>]

Hi,

I'm trying to run the following script:
  for f in $(find . -name "*.txt"); do cmd1;cmd2;cmd3; done
,where cmd1, cmd2 and cmd3 are arbiturary commands. The problem is, if 
the found file names contain a space , for example "part1 part2.txt" 
will be interpreted as "part1" and "part2.txt". I'm thinkin an esacping 
tool may be able turn it into "part1\ part2.txt" before passing it to 
"for" loop. Any thought?

Thanks,
