The <code>caffeinate</code> command prevents the computer to go into sleep mode,
|
||
|
|
just as if you would set it to never sleep in the system preferences.
|
||
|
|
Type <code>caffeinate -d</code> in your terminal and it will prevent your screen to sleep
|
||
|
|
without changing the system preferences.</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
caffeinate -d
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
You can also prevent your computer to go sleep while another process is taking place, but turn sleep
|
||
|
|
mode on again when the process is over, for that you use the same code as above, and then type the
|
||
|
|
arguments you want to run and prevent computer to go on sleep mode. For example, say you have a
|
||
|
|
big file on your desktop that you want to md5, and you want to prevent your computer to enter
|
||
|
|
the sleep mode:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
caffeinate -d ~/Desktop/bigfile
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
Doing so, your computer is now prevent to enter on sleep mode while the md5 process is running,
|
||
|
|
and automatically turn the sleep mode on again when the process is completed.
