How do I use SCP for file transfer?

“I occasionally need to move files between PCs. Tried a variety of different file transmission methods, but I always had problems. For instance, the size of the files makes them impossible to send. My friend says I might be able to copy files safely using SCP. Is there anybody to give me some tips on how SCP sends files from remote to local?”

What is SCP and how to use it for file transfer?

SCP (Secure Copy Protocol) , a command-line utility that uses SSH mechanism, enables you to securely transfer files from PC to PC. In this part, we provide you with detailed SCP commands for file transfer in three different cases.

transfer files using scp command

Here are some basic SCP command syntax and options you need to know.

The SCP file transfer command syntax is presented in the following form:

scp [OPTION] [user@]SRC_HOST:]file1 [user@]DEST_HOST:]file2

  • [OPTION]-Options are used to perform SCP-related tasks, such as installing, configuration, copy, etc.
  • [user@]SRC_HOST:]file1 - Source file.
  • [user@]DEST_HOST:]file2 - Destination file
Tips: While remote file names should contain a user and host specification, local files should be indicated using an absolute or relative path.

SCP offers a wide range of options that regulate every facet of its activity. The following are the most common ones:

  • ✍-P- Specifies the remote host ssh port.
  • ✍-p- Preserves file modification and access times.
  • ✍-q- Use this option if you want to suppress the progress meter and non-error messages.
  • ✍-C- Forces SCP to compress the data as it is sent to the destination machine.
  • ✍-r- Asks SCP to copy directories recursively.

Read the notes carefully before your operations.

Notes:
  • Linux and Mac both include the SCP command. If you use Windows, you need to download and install PuTTY or copy "pscp.exe" (SCP for Windows) into the target folder where you intend to use it.
  • The SCP command requires authentication with an SSH key or password on the remote systems since it relies on SSH (Secure Shell) tunnel to transfer data.
  • When copying files with the same name and location on both systems, take caution because SCP will automatically overwrite files.
  • To copy files, you must at least have read permission on the source file and write permission on the target system.

Case 1. SCP file transfer from local to remote

Step 1. Run the following command to copy a local file to a remote computer:

scp file.txt [email protected]:/remote/directory

  • file.txt - the name of the target file you want to transfer
  • remote_username - the username of the remote device
  • 10.10.0.2 - replace it with the IP address
  • /remote/directory - the path you want to copy the file to (If no remote directory is supplied, the file will be copied to the remote user's home directory.)

Step 2. Enter the user password to start the process.

Bonus Tip:

Run the command below to specify a new file name if you want to save the file with a different name:

scp file.txt [email protected]:/remote/directory/newfilename.txt

Case 2. SCP file transfer from remote to local

Step 1. Replace the similar information in Case 1 and run the command to transfer files from remote to local:

scp [email protected]:/remote/file.txt /local/directory

transfer from remote to local scp

Step 2. Enter the password to perform the task.

Case 3. Transfer a file between two remote computers via SCP

Step 1. Enter the following command to copy a file between two remote systems.

scp [email protected]:/files/file.txt [email protected]:/files

  • /files/file.txt- name of the target file
  • host1.com- the host you transfer files from
  • /files - the directory you want to copy files to
  • host2.com - the target host you want to transfer files to

transfer between remote systems scp

Step 2. Enter the password of both devices and the file will be directly transferred.

Notes: The SCP file transfer speed is a distinguished drawback that the users complain about most. According to user feedback, to transfer files from one computer to another, it takes about 25 minutes to send 500 Mb of a file using SCP. Besides, it requires certain technical knowledge to transfer files via SCP. Otherwise, you will get errors when running the command.

A single file smaller than 100 MB can be transferred using AnyViewer's free account, and you are only permitted to transfer up to 100 files at once. To transfer larger files, upgrade to a Professional or Enterprise plan. The following rights will thereafter be yours:
 Speedier file transfer. The transfer speed over the internet for a free account is 500 KB/s, but it can reach 10 MB/s for a paid account.
 Assign more devices to the same account to achieve direct file transfer.
 Connect to the host computer in privacy mode so that you can block the remote PC's keyboard and mouse and black its screen.
