Which commands in terminal clean drive space no apt-get clean type commands work. won't download in Software Center nor update! not CCleaner

Question

Can you give EXACT terminal commands that work WITHOUT regurgitive mere basics that don't work such as Sudo Apt-get clean/autoclean. Is it Wily defect or what? I got Linux to be simple not to become a hacker for my own PC.

Answer 1

The commands apt-get clean and autoclean are not primarily meant to free disk space. These commands are meant to work on the software packages that are installed on your computer.

• Now, if you want to know what did fill up your harddrive start with the command sudo df -m. This will tell you on which partition and in which directory the most disk space is used in MB.

  # sudo df -m

• Use the command sudo du -m --max-depth=2 within one Directory to find out which subdirectories have the biggest size in MB. This will take you to the Directory that filled up your hard disk.
  like: sudo du -m --max-depth=2 /home.
  Which will tell you which Directory of the User Account hold the most disk space in MB.

  # sudo du -m --max-depth=1 /home
  12425   /home/user1
  817     /home/user2
  13242   /home
  

  Here we see that 'user1' is using the most of the 13242 MB occupied on the /home partition

• Once you have found out what did fill up your hard disk you will be able to decide best what is to do to free disk space. Like perhaps: Deleting user files or uninstalling software.
