Swapping IP Addresses In A File With Those From Another File
Hello,
I'm looking for a way to change the IP addresses in a large host file with those of matching hostnames in another file.
For example, I have a file with
file1 contains lines like:
and file2 has:
In reality, file1 has about 800 lines, and file2 has about 100 lines, and I need to change the IP address in file1 with those new ones in file2 for the hosts that match.
I'm looking at using just sh or ksh with sed/awk, but can't seem to get the logic straight. It would be easy enuf if it were just changing one entry with sed and redirecting to new a file, but when it comes to changing 100+ entries in a file, not sure how to approach it. This is on Solaris.
Any and all help appreciated.
Thanks.
