Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Thank you.

Note that the problem being addressed in this thread didn't say anything about only wanting to remove spaces between parentheses on lines that also contain the string "httpd".

Note that the problem being addressed in this thread didn't say anything about only wanting to remove a single space between parentheses.

Note that the problem being addressed in this thread didn't say anything about only wanting to remove spaces between parentheses only lines that have exactly one <space> before the first parenthesis on that line.

Those were what I understood.

Yes, I knew that, but I considered my answer as a good starting point.

Please be careful about saying that your code works when it looks like the code that you have provided makes several assumptions that do not seem to match the requirements being addressed in this thread.

This is important, and you are right. I thought a few times to edit the post, and write: "I think this should work". But unfortunately I didn't. Sorry.

Is the position of the last field to be retained?

EDIT: howsoever, try
Code:
sed  ':L; s/\(([^ )]*\) \([^)]*)\)/\1\2 /; tL' file

Unix sed does not end a lable at a semicolon, needs a boundary:
Code:
sed  '
 :L
 s/\(([^ )]*\) \([^)]*)\)/\1\2 /
 tL
' file

or
Code:
sed  -e ':L' -e 's/\(([^ )]*\) \([^)]*)\)/\1\2 /; tL' file

And of course it does not take -r and ERE.
