Can entry duplicates in etc/hosts do any damage?

For example:

# Host Database
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.       localhost       localhost       localhost

# and stuff like that throughout the file

No, having duplicates is not a problem. Since the file is read in order, the first matching result is read, and the rest of the file is ignored. Having exact duplicates has no effect.

    Thanks! Thought so, but then again... in my country they say he who asks, roams not ;-) – Martin Nov 21 '13 at 0:32
