Discard the output Sometimes you will need to execute a command, but you don't want the output displayed on the screen. In such cases, you can discard the output by redirecting it to the file /dev/null − $ command > /dev/null Here command is the name of the command you want to execute. The file /dev/null is a special file that automatically discards all its input. To discard both output of a command and its error output, use standard redirection to redirect STDERR to STDOUT − $ command > /dev/null 2>&1 Here 2 represents STDERR and 1 represents STDOUT.

When set on a directory, Setting the setgid permission on a directory (e.g. "chmod g+s") it causes new files and subdirectories created within it to inherit its group ID, rather than the primary group ID of the user who created the file (the owner ID is never affected, only the group ID).

If you SSH to the same server a lot and don't want to type the password each time you can configure SSH so you don't have to.

First login to your terminal as normal and run

$ ssh-keygen

This will ask you the name of the key pair file you want to use.
It will suggest ~/.ssh/id_rsa
It will also create an id_rsa.pub file.

Next you need to "copy" that file to the server you want to connect to, you do by using the ssh-copy-id command.

$ ssh-copy-id user@hostname

To make an ability check, roll a d20 and add the relevant ability modifier. As with other d20 rolls, apply bonuses and penalties, and compare the total to the DC. If the total equals or exceeds the DC, the ability check is a success—the creature overcomes the Challenge at hand. Otherwise, it’s a failure, which means the character or monster makes no progress toward the objective or makes progress combined with a setback determined by the GM.
