# Pausing from the Operating System:

## Linux

If you are on Linux 
you can send signals with these commands:

 # To pause Blender:
 killall -s STOP blender

 # To start it again:
 killall -s CONT blender

Some advantages to this are that it will work
for any task, not just rendering, and that you
do not have to start blender from a terminal.
For Mac, omit `-s` and use `Blender`, not `blender`.

## Windows

You can use process explorer for this. See this question on [StackOverflow].
