Hi Miles-
I've come to use awk more. It has a bit of a learning curve, but
seems quite a bit more powerful.
Here's what I would use:
#!/bin/bash
line1=`grep SERVER test.txt | awk -F" = " '{print $1 " =
newvalue"}'` #returns SERVER = newvalue
line2=`grep CLIENT_NAME test.txt | awk -F" = " '{print $1 " =
newname"}` #returns CLIENT_NAME = newname
# Then overwrite the file
echo "$line1" > test.txt
echo "$line2" >> test.txt
exit 0
NOTE: Make sure you have the block quotes (``) around the grep/awk
commands so the variable gets what is returned from the commands, not
the string.
The grep command will pull out just that line, then awk will use " = "
as a delimiter (with the F command) and then print $1 (first value in
delimited list, SERVER) and the the string in quotes.
Then you just use echo and the greater thans to overwrite and append
to the file.
Hope this helps

I have a configuration file for an application that contains two

I'd like to be able to change these lines with a simple script. I
think sed can get me there, but I'm having a little trouble getting
it just right.
I've figured out how to replace "server.domain.ext" with
"somethingelse" if I know what the server.domain.ext string is. I
don't want to rely on knowing what the existing string is. What I
want to do is replace everything after "SERVER = " with a string of
my choosing.
Any of the fine minds on these boards have and idea?
Thanks in advance,
