CyberSecurity Linux Command

This is the second week of Beginners Linux Commands. Every week I will write about 5 Linux commands and I would encourage anyone who wants to explore the field of CyberSecurity to practice this.

1. sudo -the command is used to run a single command with root permissions. The sudo -i command is used to instill root permissions to the user for the entire duration of the SSH session.

2. touch -The command touch is used to create new files.

3. echo -The command echo is used to insert text into an existing file. The command echo "Hello World" >> /home/myfile.txt is used to insert the text “Hello World” into the file called myfile.txt.

4. cat -The command cat is used to display the contents of a file in the terminal. An example, the command cat /home/myfile.txt is used to display the contents of a file called myfile.txt.

5. mkdir -The command mkdir is used to create new directories. An example, the command mkdir /home/mydirectory is used to create a directory called mydirectory inside of the home directory.
