I am using AWS Free tier Ubuntu. It is saying that disk space full in /dev/xvda1 which is mounted on / . I am using df command to check it.
I went to the directory / and using command ls -l to check which file is taking much space. But, none of them is taking that much within / . What is the recommended way to find out which file is taking much space ?
I have attached the screenshot, please check it. You can see none of them is taking 99892768 space.

ls, is only the size of the file itself: if the file is a directory, this will not include the size of the directory contents.{}icon in the editor.sudo apt autoremove, usually this solves a problem like yours.
