Command line interface syntax for various actions
Make new directory, make [directory_name]
sudo mkdir new_directory
Remove (file or directory)
rm -i file_to_remove.txt
Using -i prompts you to confirm the deletion.
Remove directory and all of its contents without having to confirm. Obviously be careful.
[/bash]sudo rm -r directory_to_remove[/bash]
Move a file
mv [name] [new_location]
mv file.txt new_sub_directory/file.txt
Rename a file (similar to moving)
mv [name] [new_name]
mv file.txt new_file_name.txt
Copy a fold
cp -r [folder]/* [new_location]
cp -r folder/* /some_place/else/
Keep ssh sessions live
If you want to stop your SSH sessions from being shut down you can add the following line to /etc/ssh/ssh_config on your local machine.
sudo gedit /etc/ssh/ssh_config
This does remove the security feature of closing your session in case you leave your computer, but you may decide to take that risk. This sends a SSH package every 30 seconds so your server doesn’t close the connection due to inactivity.
Edit DNS Name Server
Set the DNS name server to use for your machine.
sudo nano /etc/resolv.conf
Then you can use for example (18.104.22.168 is Google public DNS, 22.214.171.124 is OpenDNS):
nameserver 126.96.36.199 nameserver 188.8.131.52
