Linux home directory cache

How can I clean HOME folder in linux?

There is a way to clean in a controlled way the $HOME folders than usually save cache files? E.g: I have a .config folder with more than 300MB. How can I clean it?. Is there a program that can be used to control the saved files? In .mozilla folder you can clean up using the Firefox options.

One that works with all applications, no. Note that the cache files should be stored in .cache, not .config. In the case of web browser, a large directory in .config is usually due to the browser’s history.

Bleachbit is a program that supports the configuration directories of many programs and is able to delete things that aren’t quite necessary (bleachbit is similiar to ccleaner on windows, if you happen to know that).

At least Ubuntu has it in it’s repositories.

You can see on repology, which distribution provides Bleachbit packages. repology.org/metapackage/bleachbit/versions

In the $HOME/.config folder there are files created by many different programs, and as such there is no easy way to manage them all.

These files should be created/managed/removed by each single application, and deleting them can (will) result in loss of data (personal configurations in this case).

Being that all the data contained should be configuration data, this folder should not contain a lot of data, 300MB is quite a lot of config.

You can enquire which subfolder contains most of the data by using the command:

and you can see by yourself which folder has grown out of control.

is it safe to delete ~/home//.cache/ [duplicate]

IF it’s cache it is probably meant to be cleared eventually, but can I just manually delete the whole .cache folder? It’s eating over 10 gigabytes on a 64 GB partition. I think it is mostly unity game engine and wine. The os is Manjaro.

Yes. But you don’t have to wipe it off indiscriminately — you can leave ~/.cache/fontconfig in place for instance.

per your recent edit, are you certain that this cache directory is multiple levels below your home directory? ~ is frequently used to represent /home/ , so it’s easy to mis-read the title of your question. Do you have any clues as to what created this extra-level .cache directory?

I wouldn’t delete «~/home//.cache/» itself, but it should be fine deleting everything below that.

Edit: I should add that I’d want to know exactly what’s taking up that much space. A handy GUI tool for that is Filelight. Or, from the shell:

This will give you directory total sizes in human readable format.

This is what I recommend doing, especially before you run that backup you’ve been meaning to do of all those dot directories that you keep putting off for some reason.

I did use a gui tool, I think it might have even been Firelight to track it down, and that is how I discovered that nearly the entire 10 GB is the unity game engine and wine.

can I assume that the .cache directory exists?

I’d like to cache some files in $HOME/.cache , but I don’t know under what OSes I can assume that it already exists. Can I try to create it myself if it does not, or is that an error? What entity creates it? Is the location of .cache standardized and by what standard?

(Linux) File System Hierarchy

The linux file system hierarchy ( man hier ) does not imply any $HOME/.cache directory. From that man page, highlighting added by me:

/home

On machines with home directories for users, these are usually beneath this directory, directly or not. The structure of this directory depends on local administration decisions.

freedesktop.org Specifications

The .config and .cache directories are specified by freedesktop.org as reasonable defaults to the environment variables $XDG_CONFIG_HOME and $XDG_CACHE_HOME . Quoted from these specifications, again highlighting is added by me:

$XDG_CACHE_HOME defines the base directory relative to which user specific non-essential data files should be stored. If $XDG_CACHE_HOME is either not set or empty, a default equal to $HOME/.cache should be used.

To follow their specifications, you might want to read $XDG_CACHE_HOME first, and if not set use $HOME/.cache and create it, if necessary. You will very often encounter these variables not set – in fact, it is not set on any of my machines.

How to clean caches in my homedir

My home directory is getting huge (100GB plus). When backupping it I notices that there are quite some caches there. Which important caches are there in my homedir and how should I clean them? One cache in particular is bothering me, the cache in .gvfs, where a copy of my network harddisk seems to be stored. How do I neatly clear this cache?

3 Answers 3

The .gvfs is where network attached folders live. If you’ve used «Places/Connect to Server», or typed smb://server/share into Nautilus, that’s where your network drive will «mount».

You need to exclude your .gvfs folder from your back up, unless you actually want your network drive and all its contents to be included in your back up.

Other places you should consider excluding :

• ~/.mozilla/**yourprofilename**/Cache
• ~/.cache (this is also where Chromium puts its cache, if you use that instead of firefox)
• ~/.thumbnails

• if you use VirtualBox, your guest systems are likely stored in .VirtualBox. On the one hand, you’ll want to back those up. On the other, they’ll be huge, so maybe you should back them up separately from your generic home drive backup?
• if you use Dropbox, you’ll probably not have much need to back that up! Exclude wherever you told Dropbox to put its folder.

Finally, you can do some of this analysis yourself! Go to your Applications menu and choose Accessories, then run «Disk Usage Analyzer» (AKA baobab).
