Command to get time in milliseconds

Question

Is there a shell command in Linux to get the time in milliseconds?

Answer 1

On OS X, where date does not support the %N flag, I recommend installing coreutils using Homebrew. This will give you access to a command called gdate that will behave as date does on Linux systems.

brew install coreutils

For a more "native" experience, you can always add this to your .bash_aliases:

alias date='gdate'

Then execute

$ date +%s%N
