4 Ways to Transfer Files Between Remote and Local Systems Over SSH

Sooner or later, you'll find yourself in a situation where you have to upload the file to the remote server over SSH or copy a file from it.

There are various ways you can transfer files over SSH. I am going to discuss the following methods here:

1. scp: Legacy command which is being deprecated
2. rsync: Popular command for file synchronization
3. sshfs: Mounting remote directory over SSH
4. sftp clients: GUI tool for accessing file over SFTP

For a successful file transfer over SSH, you need to

• have SSH access between the two machines
• know the username and password on the remote machine
• know the IP address or hostname (on the same subnet) of the remote machine

With that aside, let's see the methods for copying files between remote systems via SSH.

Method 1: Use scp command to copy files over SSH

I have read that scp is going to be deprecated. Still, it is my favorite tool for transferring files between systems over SSH. Why? Because its syntax is similar to the cp command.

Let's see how to use the scp command.

Copy files from the remote machine to your local machine

Here's the scenario. You want to copy files from the remote Linux system to the currently logged in system.

Here's a generic syntax that copies the file from the home directory of the user on the remote system to the current directory of your locally logged in system.

scp username@ip_address:/home/username/filename .

Do you see the similarity with the cp command? It's almost the same except that you have to specify username and ip address with colon (:).

Now, let me show you a real-world example of this command.

In the example above, I copied the file remote.txt from the /home/abhishek/my_file directory on the remote system to the current directory of the local machine.

This should give you a hint that you should know the exact location of the file on the remote system. The tab completion does not work on remote systems.

Copy files from your local machine to the remote machine

The scenario is slightly changed here. In this one, you are sending a local file to the remote system over SSH using scp.

This is a generic syntax which will copy the filename to the home directory of username on the remote system.

scp filename username@ip_address:/home/username

In the above example, I copied local.txt file from the current directory to the home directory of the user abhishek on the remote system.

Then I logged into the remote system to show that the file has actually been copied.

You can copy directories too

Remember I told you I like scp because of its similarity with the cp command?

Like cp command, you can also use scp to copy directory over SSH. The syntax is similar to the cp command too. You just have to use the -r option.

scp -r source_dir username@ip_address:/home/username/target_dir

You can do a lot more with it. Read some more examples of scp command in this tutorial:

Method 2: Use rsync to copy files and directories over SSH

Since scp is being deprecated, rsync is the next best tool for copying files between remote system over SSH. Actually, it is better than scp in many terms.

The command syntax is the same as scp. Older versions of rsync had to use rsync -e ssh but that's not the case anymore.

Copy files from the remote machine to your local machine

Let's say you want to copy a file from the home directory of the user on the remote system to the current directory of your locally logged in system.

rsync username@ip_address:/home/username/filename .

Let's take the same example you saw with scp. I am copying the file remote.txt from the /home/abhishek/my_file directory on the remote system to the current directory of the local machine.

Copy files from your local machine to the remote machine

Here is a generic syntax which will copy the file to the home directory of username on the remote system.

rsync filename username@ip_address:/home/username

Time to see the real world example. I am copying local.txt file from the current directory to the home directory of the user abhishek on the remote system.

How about copying directories with rsync?

It's the same. Just use -r option with rsync to copy entire directory over SSH between remote systems.

rsync -r source_dir username@ip_address:/home/username/target_dir

Take a look at this example. I copy the entire my_file directory from the remote system to the local system.

rsync is a versatile tool. It is essentially a tool for 'recursively syncing' the contents between two directories and quite popular for making automated backups.

Method 3: Using SSHFS to access files from remote system over SSH

There is also SSHFS (SSH Filesystem) that can be used to access remote files and directories. However, this is not very convenient just for copying files.

In this method, you mount the remote directory on your local system. Once mounted, you can copy files between the mounted directory and the local system.

You may need to install sshfs on your local system first using your distribution's package manager.

On Debian and Ubuntu, you may use the following command:

sudo apt install sshfs

Once you have sshfs installed on your system, you can use it to mount the remote directory. It would be better to create a dedicated directory for the mount point.

mkdir mount_dir

Now mount the desired directory on the remote machine in this fashion:

sshfs username@IP_address:path_to_dir mount_dir

Once it is mounted, you can copy files into this directory or from this directory as if it is on your local machine itself.

cp local_file mount_dir

Remember that you have mounted this file. Once your work is done, you should also unmount it:

umount mount_dir

Here's an example where I mounted the my_file directory from the remote system to the remote_dir directory on the local system. I copied the remote.txt file to the local system and then unmounted the directory.

Method 4: Use a GUI-based SFTP client for transferring files between remote systems

As the last resort, you can use an FTP client for transferring files between remote and local systems.

FileZilla is one of the most popular cross-platform FTP client. You can easily install on your local system.

Once installed, go to File->Site Manager and add the remote system details like IP address, SSH port number, username and password.

Once you connect, you can see a split window view that shows the local filesystem on the left and the remote filesystem on the right.

To transfer the file, drag and drop files from left to right or right to left. A progress bar appears at the bottom.

Which method do you prefer?

Alright! I showed various command line and GUI methods that can be used for copying files over SSH.

Now it is up to you to decide which method to use here. Do comment your preferred method for transferring files over SSH.
