Log onto the ACF and get folders set up

Commands to learn

pwd = print working directory

ls = list the contents of this location (ie folder)

hostname = what is the name of the computer that I am talking to

First, open your terminal program. You will see a prompt. This is usually a $ and indicates that the shell is waiting for input.

Where are you on your computer?

pwd

What is in this location?

ls

What is the name of your computer?

hostname

Next log into the ACF with this command (substituting your own username)

ssh [email protected]

Lets try some commands. Find out what computer you are on:

hostname

The computer name should have the word "login" on it, for example "acf-login6"

Find out where you are in the filesystem:

pwd

You should be in your home folder:

/nics/d/home/mstaton1

We are going to request access to a computer other than the login node:

qsub -I -A ACF-UTK0138 -q debug -l walltime=1:00:00,nodes=1:ppn=1,naccesspolicy=singleaccount

If you are not part of the project yet, skip the above qsub step.

Now we should be on a different computer. Let's test that by checking what computer we are on:

hostname

You should get something like acf-bc008

Now we need to get the data for our lesson. We're going to use two new commands:

wget http://swcarpentry.github.io/shell-novice/data/data-shell.zip

Check to make sure it is there:

ls

And lets decompress it:

unzip data-shell.zip
