5 Easy Ways To Free Up Space (Remove Unwanted or Junk Files) on Ubuntu
|
||
======
|
||
|
||
Most of us may perform this action whenever we fall into out of disk space on system.
|
||
|
||
Most of us may perform this action whenever we are running out of space on Linux system
|
||
|
||
It should be performed frequently, to make space for installing a new application and dealing with other files.
|
||
|
||
Housekeeping is one of the routine task of Linux administrator, which allow them to maintain the disk utilization is in under threshold.
|
||
|
||
There are several ways we can clean up our system space.
|
||
|
||
There is no need to clean up your system when you have TB of storage capacity.
|
||
|
||
But if your have limited space then freeing up disk space becomes a necessity.
|
||
|
||
In this article, I’ll show you some of the easiest or simple ways to clean up your Ubuntu system and get more space.
|
||
|
||
### How To Check Free Space On Ubuntu Systems?
|
||
|
||
Use **[df Command][1]** to check current disk utilization on your system.
|
||
|
||
```
|
||
$ df -h
|
||
Filesystem Size Used Avail Use% Mounted on
|
||
udev 975M 0 975M 0% /dev
|
||
tmpfs 200M 1.7M 198M 1% /run
|
||
/dev/sda1 30G 16G 13G 55% /
|
||
tmpfs 997M 0 997M 0% /dev/shm
|
||
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
|
||
tmpfs 997M 0 997M 0% /sys/fs/cgroup
|
||
```
|
||
|
||
GUI users can use “Disk Usage Analyzer tool” to view current usage.

### 1) Remove The Packages That Are No Longer Required
|
||
|
||
The following command removes the dependency libs and packages that are no longer required by the system.
|
||
|
||
These packages were installed automatically to satisfy the dependencies of an installed package.
|
||
|
||
Also, it removes old Linux kernels that were installed in the system.
|
||
|
||
It removes orphaned packages which are not longer needed from the system, but not purges them.
|
||
|
||
```
|
||
$ sudo apt-get autoremove
|
||
[sudo] password for daygeek:
|
||
Reading package lists... Done
|
||
Building dependency tree
|
||
Reading state information... Done
|
||
The following packages will be REMOVED:
|
||
apache2-bin apache2-data apache2-utils galera-3 libaio1 libapr1 libaprutil1
|
||
libaprutil1-dbd-sqlite3 libaprutil1-ldap libconfig-inifiles-perl libdbd-mysql-perl

|
||
mariadb-server-10.1 mariadb-server-core-10.1 mysql-common sntp socat
|
||
0 upgraded, 0 newly installed, 25 to remove and 23 not upgraded.
|
||
After this operation, 189 MB disk space will be freed.
|
||
Do you want to continue? [Y/n]
|
||
```
|
||
|
||
To purge them, use the `--purge` option together with the command for that.
|
||
|
||
```
|
||
$ sudo apt-get autoremove --purge
|
||

|
||
|
||
### 2) Empty The Trash Can
|
||
|
||
There might a be chance, that you may have a large amount of useless data residing in your trash can.
|
||
|
||
It takes up your system space. This is one of the best way to clear up those and get some free space on your system.
|
||
|
||
To clean up this, simple use the file manager to empty your trash can.

||
### 3) Clean up the APT cache
|
||
|
||
Ubuntu uses **[APT Command][5]** (Advanced Package Tool) for package management like installing, removing, searching, etc,.
|
||
|
||
By default every Linux operating system keeps a cache of downloaded and installed packages on their respective directory.
|
||
|
||
Ubuntu also does the same, it keeps every updates it downloads and installs in a cache on your disk.
|
||
|
||
Ubuntu system keeps a cache of DEB packages in /var/cache/apt/archives directory.
|
||
|
||
Over time, this cache can quickly grow and hold a lot of space on your system.
|
||
|
||
Run the following command to check the current utilization of APT cache.
|
||
|
||
```
|
||
$ sudo du -sh /var/cache/apt
|
||
147M /var/cache/apt
|
||
```
|
||
|
||
It cleans obsolete deb-packages. I mean to say, less than clean.
|
||
|
||
```
|
||
$ sudo apt-get autoclean
|
||
```
|
||
|
||
It removes all packages kept in the apt cache.
|
||
|
||
```
|
||
$ sudo apt-get clean
|
||
```
|
||
|
||
### 4) Uninstall the unused applications
|
||
|
||
I would request you to check the installed packages and games on your system and delete them if you are using rarely.
|
||
|
||
This can be easily done via “Ubuntu Software Center”.

||
### 5) Clean up the thumbnail cache
|
||
|
||
The cache folder is a place where programs stored data they may need again, it is kept for speed but is not essential to keep. It can be generated again or downloaded again.
|
||
|
||
If it’s really filling up your hard drive then you can delete things without worrying.
|
||
|
||
Run the following command to check the current utilization of APT cache.
|
||
|
||
```
|
||
$ du -sh ~/.cache/thumbnails/
|
||
412K /home/daygeek/.cache/thumbnails/
|
||
```
|
||
|
||
Run the following command to delete them permanently from your system.
|
||
|
||
```
|
||
$ rm -rf ~/.cache/thumbnails/*
|
||
```
