lsb_release -a
The lsb_release -a command is used to display detailed information about the Linux distribution on your system.
It stands for "Linux Standard Base release" and provides information such as the distribution's name, release number, codename, and more.
cat /etc/os-release
Running the cat /etc/os-release command in the terminal will display the contents of the /etc/os-release file, which contains information about the Linux distribution installed on your system.
ssh-keygen -t rsa -b 2048 -C "your email"
Replace "your email" with your actual email address.
The -t parameter specifies the type of key to create (in this case, RSA).
The -b parameter specifies the key length.
The -C parameter provides a comment (usually your email address) to help you identify the key later.
You can choose the path and filename.
If you just want to use the default name, press Enter, otherwise, provide the name/path of the file.
Enter file in which to save the key (/home/elitebughunter/.ssh/id_ed25519):

/home/elitebughunter/.ssh/ssh_key_mnt_elementary

ls ~/.ssh/
cat ~/.ssh/ssh_key_mdt.pub
