The Linux Filesystem

The root (/) of the filesystem is at the top of the tree, and the following are the most important subdirectories to know:

/root The home directory of the all-powerful root user

/etc Generally contains the Linux configuration files—files that control when and how programs start up

/home The user’s home directory

/mnt Where other filesystems are attached or mounted to the filesystem

/media Where CDs and USB devices are usually attached or mounted to the filesystem

/bin Where application binaries (the equivalent of executables in Microsoft Windows or applications in macOS) reside

/lib Where you’ll find libraries (shared programs that are similar to Windows DLLs)
