The /, or root directory.
The Linux Filesystem Hierarchy is used to help determine the file structure in the Linux Operating System. It defines the Directory structure and directory contents.
It is the Home Directory.
mv file /path/to/directory
root directory
If the directory you're interested is my_dir, then do: du -sk my_dir/* | sort -nr | head
The first file system Linux supported was the MINIX file system.
Unlike Windows, Linux has a unified file system. In Windows, all paths start with a drive letter, like C: ( C:\Users\Joe\Documents\readme.txt ) A flash drive may mount as F:, and a CD may mount as E:. In Linux, there are no drive letters, and all paths begin from the root directory (/) ( /home/joe/readme.txt ) Storage devices will instead mount to folders. A flash drive may mount to /media/Lexar So, to answer your question, Linux only has one directory tree, the uppermost level of which is known as the file system's root.
rm filenameorrm -r directoryname
