Command settings for RTC on linux

This is the command I use to setup my Beaglebone with RTC DS133833.

Set Date and Time manually:

date --set 2015-01-23
date --set 21:08:00

Change region/timezone:

dpkg-reconfigure tzdata

Read RTC date time value:

hwclock -r -f /dev/rtc1

Write date time value to RTC:

hwclock -w -f /dev/rtc1

another command is

hwclock -s -f /dev/rtc1

To store date time in CMOS(Non-volatile memory):

hwclock --systohc

BleachBit (Cruft Cleaner) - a CCleaner for Ubuntu

Windows users will be familiar with applications like CCleaner, which scan for and clean out junk files, empty folders, bloated caches, and obsolete packages. For a a similarly quick and effortless click n’ clean solution on Ubuntu try BleachBit.

It is a powerful tool, so do pay attention to what you’re cleaning. Don’t aimlessly check every box; not everything that it can clean needs to be. Play it smart; when in doubt, leave it out.
