Making the the OS sleep for some time

[vickey_20]

I find it a necessity to make my pc go into sleep mode as i take break in between. But don't know how to make it go in sleep state ?? I even don't want to shut it down as I come back quickly...

If you know how long you will be gone, you can use sleep command Linux Command Directory: sleep - O'Reilly Media but I don't know what to use if you don't know when you'll be back.

You could also look into either suspending it, or making it hibernate. Here is some info on that.

The aforementioned sleep command is for postponing the execution of another command. It doesn't put the whole system to sleep.

You would do this via the ACPI.
Advanced Configuration and Power Interface - Wikipedia, the free encyclopedia

Most desktop environments bring their own interfaces to manage this, but a general command line tool would be acpitool(1) - Linux man page.
