Clear ubuntu garbage

Clear ubuntu spam-general Linux technology-Linux technology and application information. The following is a detailed description.

Linux and windows do not generate useless junk files, but linux does not automatically delete these files during cache upgrade. Today we will talk about how to clean these junk files.

1. Very useful cleanup commands: (Be careful when using !!!!)
Sudo apt-get autoclean
Sudo apt-get clean
Sudo apt-get autoremove

These three commands mainly clean up and upgrade the cache and useless packages.

2. Clear the cache files of opera firefox:
Ls ~ /. Opera/cache4
Ls ~ /. Mozilla/firefox/*. default/Cache

3. Clear isolated packages in Linux:
In the graphic interface, we can use: gtkorphan
Sudo apt-get install gtkorphan-y

Run the following command on the terminal: deborphan
Sudo apt-get install de borphan-y

4. Uninstall: tracker
Generally, I only need to install ubuntu and delete tracker first. This will not only generate a large number of cache files, but also affect the boot speed. So you can delete it in Suntory.

5. Delete unnecessary kernels: Do not delete any errors. Remember !!
Run the command dpkg -- get-selections | grep linux on the terminal.
Kernel files with images
Delete the old kernel file:
Sudo apt-get remove Kernel File name (e.g.: linux-image-2.6.27-2-generic)
Delete the kernel and release the space. The space should be-MB.
Finally, don't forget to look at the current kernel: uname-
