Introduction

Bash is a shell scripting language. It is used to run programs on a Unix-like system (Linux, Mac). This is a collection of useful commands and shortcuts for Bash.

Commands​

Listing files​

ls

Changing directories​

cd

Listing mounted volumes​

mount

Changing to a mounted drive​

cd /mnt/drive

If the volume name has spaces in it, you will need to put it in quotes. For example, if the volume name is "My Drive", you would type:

cd "/mnt/My Drive"

Moving Files and Directories​

mv [source] [destination]

Copying Files and Directories​

cp [source] [destination]

Using SSH​

SSH is a secure shell. It is used to connect to remote servers. The following commands are used to connect to a remote server.

Connecting to a remote server​

ssh [username]@[server]

Note: The username and server are case sensitive. Also, you can use the IP address instead of the hostname.

You might need to add the public key of the server to your known hosts file. This is done by typing the following command.

ssh-keygen -R [server]

You might need a .pem file to connect to a remote server. This is done by typing the following command.

ssh-keygen -t rsa

After generating the key, the ssh command to connect to the server will look like the following.

ssh -i [path to .pem file] [username]@[server]
