Transfer files to/from Curnagl

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

1. If you are familiar with the terminal use: scp command
2. If you are familiar with graphich interfaces, use: FileZilla

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 option –r after scp.

From your own computer to the cluster

Nothing better than an example to understand this command. Suppose you have a file (of any type) called tutorial on your own computer. Here are the steps to copy this file to Curnagl cluster:

1. Open a first terminal:

   • 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.

This step is not mandatory but it allows you to get the path where you want to paste tutorial. One tip: in case the path where you want to paste tutorial is very long (e.g. /users/<username>/<project>/<sub_project>/<sub_sub_project>/<sub_sub_sub_project>) or simply to avoid mistakes when writting the path: use pwd command in the right folder on this second terminal connected to Curnagl, copy the whole path and paste it to the end of the scp command (see below).

Open two shell interfaces/terminals: first one where the current path is on your own/local laptop, the second one where you are logged on Curnagl frontend.

3. Let's copy/paste tutorial file to /users/<username>/<project> on Curnagl, with <username> as your personal username and <project> as the directory where tutorialshould be pasted. On the first terminal, with your working directory being the one where tutorial is located, run the following command (it will ask for your password):

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

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 replace . with the correct path.

Second option: Filezilla

First, you must install FileZilla on your computer. Please refer to: https://filezilla-project.org/ (install client version, more documentation on https://wiki.filezilla-project.org/Client_Installation).

Here are the steps to transfer data to/from Curnagl with FileZilla:

1. Open FileZilla. Performa a quick connection to Curnagl. Fill in Host with:sftp://curnagl.dcsr.unil.ch
2. Then fill in Username, Password, and Port with 22. Click on Quickconnect. Refer to the screeshot below.

You have the remote site window on the right.click and move file/folder from the left window (local site) to the right window (remote site). Inversely, to transfer data from Curnagl: click and move file/folder from the right window (remote) to the left window (local site).

Instead of /home/margot/ on the left local site (respectively /users/msirdey/ on the right remote site), you should see your own path on your computer (respectively on Curnagl).

FileZilla keeps remote sites in memory. For future transfers, click on the arrow on the right of Quickconnect and choose sftp://curnagl.dcsr.unil.ch.
