BASIC LINUX COMMANDS
BASIC LINUX COMMANDS: These are the Common Linux Operations
mkdir (Make Directory)
We’re gonna need some directories to store all these files we’ve been working on.
The mkdir command (Make Directory) is useful for that, it will create a directory if it doesn’t already exist. You can even make multiple directories at the same time.
COPY & RUN –> $ the below commands
mkdir sample folder
cd (Change Directory)
cd (Change Directory) command is one of the most important and most widely used as system administrators. For admins on a headless server, ‘cd’ is the only way to navigate to a directory to check log, execute a program/application/script and for every other task.
COPY & RUN –> $ the below commands
cd sample
Touch
Touch Let’s learn how to make some files. A very simple way is to use the touch command.
Touch allows you to the create new empty files.
COPY & RUN –> $ the below commands
touch code1.txt
Mv (Move)
mv code1.txt /home/ubuntu/folder
cp (Copy) Let’s start making some copies of these files. Much like copy and pasting files in other operating systems, the shell gives us an even simpler way of doing that.
cp code2.txt ./sample
rm (Delete)
rm code2.txt
Super User Do
super user do Sudo stands for either “substitute user do” or “super user do” and it allows you to elevate your current user account to have root privileges temporarily.
COPY & RUN –> $ the below commands
sudo su
Installing Software
Install command is used to copy files and set attributes. It is used to copy files to a destination of the user’s choice, If the user want to download and install a ready to use package on GNU/Linux system then he should use apt-get, apt, yum, etc depending on their distribution.
COPY & RUN –> $ the below commands
sudo apt-get update
