some basic Ubuntu Linux commands that you can learn to use on an EC2 instance in AWS:
cd: Change directory. This command is used to change the current working directory. For example, "cd /var/log" will change the working directory to "/var/log".
ls: List files. This command is used to display a list of files and directories in the current working directory. For example, "ls -l" will display a detailed list of files and directories.
mkdir: Make directory. This command is used to create a new directory. For example, "mkdir mynewdirectory" will create a new directory named "mynewdirectory".
rm: Remove. This command is used to remove a file or directory. For example, "rm myfile.txt" will remove the file named "myfile.txt".
cp: Copy. This command is used to copy a file or directory. For example, "cp myfile.txt /mynewdirectory/" will copy the file named "myfile.txt" to the directory "/mynewdirectory/".
mv: Move. This command is used to move a file or directory. For example, "mv myfile.txt /mynewdirectory/" will move the file named "myfile.txt" to the directory "/mynewdirectory/".
nano: A text editor. This command is used to open a text editor. For example, "nano myfile.txt" will open the file named "myfile.txt" in the nano text editor.
chmod: Change mode. This command is used to change the permissions of a file or directory. For example, "chmod 755 myfile.txt" will change the permissions of the file named "myfile.txt" to allow read, write, and execute access for the owner and read and execute access for everyone else.
sudo: Superuser do. This command is used to execute a command with superuser privileges. For example, "sudo apt-get update" will update the system packages with superuser privileges.
These are just a few basic Ubuntu Linux commands that you can learn to use on an EC2 instance in AWS. There are many more commands available, so feel free to explore and learn more!
"Note: After using the EC2 instance, please 'stop' the instance. Do not terminate it."
This is a good practice to avoid unnecessary charges and to ensure that your data is saved. When you stop an EC2 instance, you can easily start it again later and resume where you left off. If you terminate an instance, you will lose any data stored on that instance and will have to start over from scratch.
