Re: Using sed to find and replace ip address

Thanks Chris and Kevin. I made it a little further. My problem was the missing / after the last 109. It now runs successfully, but I end up with an empty file. Here is the command I ran. I did try it using [] around the periods as well, but that didn't make a difference. I also tried adding "g" at the end, but that didn't help either. I'm probably doing something silly. I double checked the name of the file I'm testing with.

STRQSH CMD('sed "s/10\.2\.0\.109/10.202.0.109/" /home/jdeane/httpd_dr.conf > /home/jdeane/httpd_dr.conf')

Here are the first few lines of the configuration file.

# Configuration originally created by Create HTTP Server wizard on Thu Jan 18 15:55:35 EST 2018

As you can see, the second line contains the ip address I want to update. Not sure why it is wiping out the entire file.

Hi,

I'm trying to use sed to find and replace an IP address in a Apache config
file as part of switching over to our DR machine. I want to script the
process rather than doing it manually. I need to replace 10.2.0.109 with
10.202.0.109. Here is what I have tried based on examples I found online.
Since there are periods involved in the string, I thought I needed to
escape them.

STRQSH CMD('sed "s/10\.2\.0\.109/10\.202\.0\.109"
/home/jdeane/http_dr.conf > /home/jdeane/http_dr.conf')

When I run this, I receive an error "there is an incomplete substitution
in a regular expression". Anyone have any ideas?
