Command for resolving ip address for host entry in /etc/hosts

dnshosts

I'm looking for a command that will let me resolve a host name in /etc/hosts to its corresponding IP address.

nslookup ignores entries in /etc/hosts file.

ping will find entries in /etc/hosts but is difficult/slow to capture the output.

On macOS you can use dscacheutil, the Directory Service Cache Utility, for this purpose.

dscacheutil -q host -a name localhost

The output looks like:

name: localhost
ipv6_address: ::1

name: localhost
ip_address: 127.0.0.1

(On Linux, the equivalent is getent.)
