How do you clean up Linux and why?

[blackbird34]

I'd advise Bleachbit over the Janitor, Janitor's been known to be buggy.

sudo -s
apt-get autoremove && apt-get autoclean -y

Edit. This one was plain wrong. I stand corrected.
It must be quoted if written in one line

root@host:~# apt-get autoremove && apt-get autoclean -y

/bin/bash: apt-get autoremove;apt-get -y autoclean: command not found

Edit. Corrected. ibjsb4 and sudodus, thanks for pointing out my mistake.
Once again, when written on one line.

Edit. The paragraphs below are correct now, but completely off-topic here.

It's often used to get redirections right with sudo. E.g.

sudo echo 10 >/proc/sys/vm/swappiness

is wrong as sudo only affects echo, but redirections are executed with regular user's permissions, and normal user doesn't have write access to /proc/sys/vm/swappiness. To get redirection work, this could be rewritten as either

echo 10 | sudo tee /proc/sys/vm/swappiness

or

sudo sh -c 'echo 10 >/proc/sys/vm/swappiness'

This example is somewhat contrived as the right way to change swappiness is

sudo sysctl vm.swappiness=10

I definitely suggest bleachbit. When the issue arose about ever-cookies, the bleachbit dev was the first to confirm deletion of said cookies. Flash and all other manner of cruft is removed. It's also one that I use for Windows, just too bad it doesn't clean the registry. Then I'd put over and above CCleaner.

Once again, when written on one line.

sudo -s  'apt-get autoremove;apt-get -y autoclean'

host@host:~$ sudo -s 'apt-get autoremove;apt-get -y autoclean'
[sudo] password for host:
/bin/bash: apt-get autoremove;apt-get -y autoclean: command not found

Once again it does not work, have you even tried it?

[blackbird34]

host@host:~$ sudo -s 'apt-get autoremove;apt-get -y autoclean'
[sudo] password for host:
/bin/bash: apt-get autoremove;apt-get -y autoclean: command not found

Once again it does not work, have you even tried it?

Once you are root, you can just do

apt-get autoremove && apt-get -y autoclean

The '&&' always works, as a way of stringing two commands together. I do sudo apt-get update && sudo apt-get dist-upgrade for all my updates, flawless.

Thank you blackbird34, Yes your command will work fine. I was just trying to find out why schragge would post non-working commands and also would like to know what swappiness has to do with cleaning up linux.

No, I haven't. I read about sudo -s in the sudo manual page, and somehow assumed it would work. Thank you for correcting my misconception! Lesson learned. As I see now, sudo -s is equivalent to sudo -i except for the environment not being changed to that of root. That means it will work only in the following form (yes, now I've tested it):

sudo -s eval 'apt-get -y autoremove;apt-get autoclean'

or, better yet

sudo -i eval 'apt-get -y autoremove;apt-get autoclean'

Note also that it makes more sense using the option -y/--assume-yes with autoremove than with autoclean as autoclean usually won't ask you any questions anyway.

Just for fun, the shortest command equivalent to the sudo -s eval shown above is probably

sudo sh -c '$0 -y autoremove;$0 autoclean' apt-get
