Linux command to get time in milliseconds

How can I get time in milliseconds in a Bash shell script?

Solution

  • date +%s%N returns the number of seconds + current nanoseconds.

    Therefore, echo $(($(date +%s%N)/1000000)) is what you need.

    Example:

    $ echo $(($(date +%s%N)/1000000))
1535546718115

    date +%s returns the number of seconds since the epoch, if that's useful.
