Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

    $ docker ps -q -a | xargs docker rm
   

-q prints only the container IDs -a prints all containers

Notice that it uses xargs to issue a remove container command for each container ID

2. Delete all untagged images
