Howto search and replace...

Howto search and replace for a pattern over all system files ?

It's faster with vi, ed ?

try a perl-expression. 
find / '!' -type d -exec perl -e s/foo/bar/baz '{}' ';'
this is definitely not ready-to-run, but it's a good point to start 
from. look at the perl man page.

sed.  And a bit of shell script.  For instance (off the top of my head,
so no guarantees):

for i in $file_list; do \
mv $i $i~; \
sed -e s/old/new/g  $i~  $i; \
done

And that'll even leave the old version of the file with a ~ extension.
$file_list can be generated with something along the lines of:

$file_list=`find /etc -type f`

That'd give you a list of all the files in /etc.

Let me guess - you're trying to change you're domain name? :)

perl is designed for this kind of thing.

use it carefully, though--AFTER you back everything up!

#!/usr/bin/perl
use File::Find;

see 'man File::Find' (or perldoc 'File::Find') for the
full poop.
