Transfer files to/from Curnagl

How do I transfer my code to Curnagl ? How do I get my results back on my computer ?

 

There are two main options to transfer data to/from Curnagl:

1.  You are familiar with terminal/bash command lines: use the `scp` command, see below.

2.  You are used to work with graphic interfaces: use FileZilla, see below.

First option: scp command

scp <FILE_TO_COPY> <FOLDER_WHERE_YOU_PASTE_IT>

scp –r <FOLDER_TO_COPY> <FOLDER_WHERE_YOU_PASTE_IT>

The latter command refers to a folder transfer. To transfer a folder, add the recursive command –r after scp. 

From your own computer to the cluster. 

Never better than an example to understand this command. Suppose you have a file (of any type you want!) called tutorial on your own computer. Here are the steps to copy this file to Curnagl cluster: 

1. Depending on your distribution.

LINUX: open a terminal in the folder where is the file tutorial , or open a terminal and then use cd command to go to the right place.

MAC: type terminal in the search field, choose `terminal`, then use cd command to go to the right place.

WINDOWS: type cmd in the menu, choose Command prompt or Powershell, then use cd command to go to the right place.

2. Open a second terminal. Connect to Curnagl with the  ssh command you are used to.

You now have two open terminals: one where you are on your own computer and one where you are connected to Curnagl. Suppose you want to copy/paste tutorial to /users/<username>/<project> on Curnagl, where <username> is your username and <project> is the folder where you want to paste tutorial. 

3. On the terminal from step 1 (which can access tutorial file since you are supposed to be in the right folder), type the following command (it will ask for your password):

scp tutorial <username>@curnagl.dcsr.unil.ch:/users/<username>/<project>

 

One tip the reason to open the second terminal on Curnagl is that if your path where you want to paste `tutorial` is very long (e.g.  `/users/<username>/<project>/<sub_project>/<sub_sub_project>/<sub_sub_sub_project> `): use `pwd` command in the right folder, copy the whole path and paste it to the end of the `scp` command.

 A few tips: the reason to open the second terminal on Curnagl is that if your path where you want to paste `tutorial` is very long (e.g.  `/users/<username>/<project>/ <sub_project>/ <sub_sub_project>/ <sub_sub_sub_project> `): use `pwd` command in the right folder, copy the whole path and paste it to the end of the `scp` command.  

You can check either the copy/paste performed well or not: use `ls` command on Curnagl and check either if `tutorial` file is there or not. 

 

From the cluster to your own computer. 

Only step 3 changes: 

` scp <username>@curnagl.dcsr.unil.ch:/users/<username>/<project>/tutorial .` 

In case you do not want to paste it in the current folder (that is for what `.` stands for at the end of the above command line), simply replacee `.` with the correct path.
