Sed problem

When installing apache22, in the file httpd.conf the following line

Code:
#ServerName www.example.com:80

needs to be replaced commonly by

Code:
ServerName localhost:80

I tried using the following

Code:
sed -i 's/#ServerName www.example.com:80/ServerName localhost:80/' /usr/local/etc/apache22/httpd.conf

but the error message was:

Code:
sed: 1: "/usr/local/etc/apache22 ...": extra characters at the end of l command

and the substitution was not made. What is the correct sed command to achieve the substitution?

EDIT: This probably has to do with the "#" at the start of the line as the man page states:
Quote:
The ``#'' and the remainder of the line are ignored (treated as a
comment), with the single exception that if the first two charac-
ters in the file are ``#n'', the default output is suppressed.
This is the same as specifying the -n option on the command line.
It would still be useful to know how to solve this problem.

First, don't use the -i option to sed without giving a backup extension, especially when you are having problems with it.

Second, there is nothing wrong with your sed command (unless you are using a sed which doesn't support -i or a *BSD sed which requires a backup extension with -i).

Thanks that worked. I currently have this:

Code:
sed -i '' -e 's/#ServerName www.example.com:80/ServerName localhost:80/' /usr/local/etc/apache22/httpd.conf
