What's the problem you're aiming to solve? I'm rather hoping there's a
more elegant (and less error-prone) way of achieving the same without
sedding a conf(?) file on every boot.

Jesus,
I was just curious is it something that keeps getting changed or is this a one time change?
If you alter a conf and it was booted with old conf and it keeps changing back from your
new back to the old.
Then we will need more information if you alter a file that after boot comes back it is
a default override taking effect.

Leo Jackson

Well, I don't know about bash command but I know about sed.

Maybe now with bash, but with perl it can be done in place quite
handily.
perl -i -pe 's/WORDS/REPLACEMENT/' my.conf

It can be done "inplace" with `rm' in place or `mv':
(rm /etc/conf.file;
while read line; do
echo ${line/old_word/new_word}
done >/etc/conf.file) </etc/conf.file

True, but that's using external tools. My point was that it's difficult
to do simply with bash (which is what the OP asked for). If you're
allowing the use of external tools, sed is much easier.
