sed is it! Thanks to John <john@dhh.gt.org>, Michal 
<frankie@tristvrte.sk>, und eechi von akusyumi 
<vinauser@netvigator.com> for the replies. Now my problem is how to 
make sed recurse through directories. I managed to chain commands 
together as:

for i in *.txt ; do mv $i $i.tmp ; sed s/foo/boo/g $i.tmp > $i ; done

Can anybody comment on this little script? This appears to work, but 
may be inefficient. And it's one step removed from what I want, 
recursive processing. That is, to have sed process files in 
subdirectories of the current directory. I prefer something that can 
receive its input from find:

find . -name *.txt
