A Linux administrator recently changed the IP addresses of all the web servers from 10.10.50.x to 10.10.100.x. The administrator needs to update the serverlist.txt file to reflect the change.
The file contains the following:
10:WebSvr01:10.10.50.21:Main
11:WebSvr02:10.10.50.22:Acconting
12:WebSvr03:10.10.50.23:Intranet
20:NFS01:10.10.20.21:FileServer
30:SMTP01:10.10.30.31:Email
Which of the following commands will change the IP addresses and update the files in place?
