Sed find and replace ip addresses in a file

nick - Latest answer on Aug 15, 2009 2:52pm BST

Hello,
What is the easiest way to replace a couple of IP addresses on the same line separated by a space in a bunch of files called *.out?
i.e.
file1.out
044=10.1.10.200 10.2.10.200
want to replace them with
044=192.168.1.200 192.168.2.200
Thanks,
nick.

jp@MDK:~/tmpfs ssh$ cat file1.out
044=10.1.10.200 10.2.10.200

jp@MDK:~/tmpfs ssh$ sed '/^044/ s/=.*/=192.168.1.200 192.168.2.200/' file1.out
044=192.168.1.200 192.168.2.200

jp@MDK:~/tmpfs ssh$ sed -i.bak '/^044/ s/=.*/=192.168.1.200 192.168.2.200/' file1.out

jp@MDK:~/tmpfs ssh$ cat file1.out
044=192.168.1.200 192.168.2.200

jp@MDK:~/tmpfs ssh$ cat file1.out.bak
044=10.1.10.200 10.2.10.200

jp@MDK:~/tmpfs ssh$

Hi,

What is the common pattern ? 044 or 10.1.10.200 ?
