Thank you very much for your interest.
I was premature in my assertion that sed "hangs".
But it takes a crazy crazy time.
I was working on a directory of 6000 text files when I reported as above.
This is what happened with a directory of <90 files:

~> find archive -type f | wc
     87      87    1698
~> time find archive -type f | xargs sed -i 's/string1/string2/g'
real    1m2.587s
user    0m1.200s
sys     0m12.884s

More than a minute for 90 files is just extraordinary.
Anybody else having a similar experience?
(Thank you again.)

Fergus
