This command can be used with various options to customize its behavior. For example, using the -l option will display detailed information about each file.

Here’s an example of how to use the ls command:

root@kali:~# ls -l
total 24K
drwxr-xr-x 2 root root 4.0K Apr 12 14:37 bin
-rw-r--r-- 1 root root 1.3K Apr 12 14:37 etc
lrwxrwxrwx 1 root root   26 Apr 12 14:37 home -> /root/home
drwxr-xr-x 2 root root 4.0K Apr 12 14:37 lib
-rw-r--r-- 1 root root 1.3K Apr 12 14:37 proc
lrwxrwxrwx 1 root root   28 Apr 12 14:37 run -> /root/run

2. cd - Change Directory

The cd command is used to change the current working directory in Kali Linux. This command can be used with various options, such as -L for symbolic links and -P for absolute paths.

root@kali:/etc# ls -l
total 24K
-rw-r--r-- 1 root root  16 Apr 12 14:37 alternatives
-rw-r--r-- 1 root root   4 Apr 12 14:37 apt
...

3. mkdir - Make Directory

The mkdir command is used to create a new directory in Kali Linux. This command can be used with various options, such as -p for creating parent directories if they do not exist.

root@kali:~# rm /tmp/newdir

5. cp - Copy Files and Directories

The cp command is used to copy files and directories in Kali Linux. This command can be used with various options, such as -r for recursive copying.

Here’s an example of how to use the cp command:

root@kali:~# cp /etc/alternatives /tmp/

6. mv - Move Files and Directories

The mv command is used to move files and directories in Kali Linux. This command can be used with various options, such as -b for overwriting existing files.

Here’s an example of how to use the mv command:
