Command line interface syntax for various actions
Make new directory, make [directory_name]
[bash]sudo mkdir new_directory[/bash]
Remove (file or directory)
[bash]rm -i file_to_remove.txt[/bash]
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]
[bash]mv file.txt new_sub_directory/file.txt[/bash]
Rename a file (similar to moving)
mv [name] [new_name]
[bash]mv file.txt new_file_name.txt[/bash]
Copy a fold
cp -r [folder]/* [new_location]
[bash]cp -r folder/* /some_place/else/[/bash]
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.
[bash]sudo gedit /etc/ssh/ssh_config[/bash]
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.
[bash]sudo nano /etc/resolv.conf[/bash]
Then you can use for example (184.108.40.206 is Google public DNS, 220.127.116.11 is OpenDNS):
[bash]sudo lshw[/bash] will provide infor on your system, CPU types, 32 v 64 bit…
