What Linux commands do you use to connect to a server and edit files?

To connect to the server, the ssh command is usually used:

ssh user@server_address

To edit a file on the server, you can use text editors available in the terminal, such as:

• vim filename — a powerful editor with many features
• nano filename — simpler and more user-friendly for beginners
• vi filename — a classic editor

Example:

ssh user@server_address
vim /path/to/file.txt

You can also use scp or sftp to copy files between your local machine and the server.
