bash script question???

[shaggy112]

I am using rsync to sycronize a server running apache to serve a web site.

The problem is that in the html code, the actual fqdn is referenced.

I want to script something that will grep each file in a specific dir where the code is held, and change it to the ip of the server that I am syncing.

Hope this makes sense.
Thanks

you could try something like
cat file|awk s/oldip/newip/g >file
(or is that suppose to be sed?)

I'd use sed for that. Awk might be able to do that too, but it's mainly for something different...

thanks for the replies.

I try this:
cat file | sed s/oldip/newip/

It scrolls accross the screen the correct output (as in oldip is changed to newip), but the file itself is untouched.

I tried '...> file', but that didn't do it either.
Any addl help would be great
Thanks!

Try

sed -e s/oldip/newip/ filename | tee filename

calvin,

thanks. that worked except when there was more than one occurence in one line. in other words....when i had the ip twice or more, it would only change the first.

thanks

put a "g" at the end of the sed expression:

sed -e s/oldip/newip/g filename | tee filename

This means "global" replacing.

thanks.

this works great.

one other question though. How do I make it do things recursively...as in whole directories at a time? I thought that a star might work but it did not. Any ideas?
thanks
