User space refers to everything that happens outside of the kernel. AmongRead More →

3.3. The File System 3.3.1. The Filesystem Hierarchy Standard As with other Linux distributions, Kali Linux is organized to be consistent with the Filesystem Hierarchy Standard (FHS), allowing users of other Linux distributions to easily find their way around Kali.

The top-level directories are described as follows. /bin/: basic programs /boot/: Kali Linux kernel and other files required for its early boot process /dev/: device files /etc/: configuration files /home/: user's personal files /lib/: basic libraries /media/*: mount points for removable devices (CD-ROM, USB keys, and so on) /mnt/: temporary mount point /opt/: extra applications provided by third partiesRead More →
