I have a file with numbered host names. I want to change the name while preserving the numbers.
CHANGE THIS:
server1.domain.com
server2.domain.com
server3.domain.com
server4.domain.com
server1.otherdomain.com
server2.otherdomain.com
TO THIS:
host1.domain.com
host2.domain.com
host3.domain.com
host4.domain.com
server1.otherdomain.com
server2.otherdomain.com
I have tried this but it does not work
:%s/server*.domain.com/host*.domain.com/g
You could use a capture group, and make the match a bit more specific by matching the numbers and escaping the dot.
Then in the replacement use the capture group denoted as \1
:%s/server\([0-9]\+\.domain\.com\)/host\1/g
Result:
host1.domain.com
host2.domain.com
host3.domain.com
host4.domain.com
server1.otherdomain.com
server2.otherdomain.com
