How do I get a single entry from group, password file?

[petulia3478]

An east way of getting an entry from database file like /etc/group, /etc/passwd, etc

$ getent group opscode
opscode:x:750:opscode

or from the password file

$ getent passwd opscode
opscode:x:750:750::/opt/opscode/embedded:/bin/sh

Any database file support by the name service switch libraries, file mainly found in /etc/nsswitch.conf
