5. ls Command

This command is one of the most useful commands in Kali Linux that lists directory contents of files and directories. With ls command, you can easily list out all hidden files in a directory with -a attribute and for more detailed output you can use -l attribute.

The command used for creating directories is mkdir. For example, if you want to create a directory under Desktop called techchains, open a terminal and type the following command:

Command: mkdir /root/Desktop/techchains

8. cat Command

The rm (remove) command is used to delete files. When used recursively, it may be used to delete directories.

The removal process unlinks a file name in a file system from its associated data, and marks that space on the storage device as usable by future writes. In other words, when you remove a file, the data in the file isn’t changed, but it’s no longer associated with a filename.

12. users Command

This command display login names of users currently logged in on the system.
