SCP is closely related to the SSH protocol and was indeed born from the same idea.
SCP makes sure that data remains confidential & untampered during transit as an extension of the SSH protocol.
First, lets understand how this SCP works, and then well see the scp commands.
What is SCP?
SCP stands for Secure Copy Protocol.
Its widely used for transferring data securely over a online grid.
SCP relies on SSH (Secure Shell) to establish a secure connection and encrypt the data during transit.
How SCP Works?
It uses the same security mechanisms as SSH, including encryption and authentication, to protect data during transmission.
When to Use SCP?
SCP is particularly useful in the following scenarios.
Remote Collaboration
SCP can be used to share files securely with collaborators or team members in different locations.
you’re free to use various options to customize the transfer process.
It can be used to disable strict host key checking.
Source
The source specifies the file or directory you want to copy.
It can be a local path or a remote path depending on the context.
Destination
The destination specifies where you want to copy the source.
Like the source, it can also be a local path or a remote path.
/path/to/destination/:This is the destination path on the remote server where the file will be copied.
Example: In my case, I have chosen one remote server for transferring the file.
Here I have selected a zip file to copy.
Output
And the output will look like this if there is no error in connecting to a remote server.
Example
This is just the sample output in my case.
Timestamp varies depending on connection speed.
Here, I mentioned the whole directory to copy the files.
Source and destination paths are the same as before.
Here, I have tried with a .png extension.
you’ve got the option to use any port you want.
The source and destination address are the same as explained previously.
The sample output will look like this.
The output will look like this.
The old and new file extensions should be the same while executing this command.
This command also preserves symbolic links during the copy.
This command directly transfers file.txt from remotehost1 to remotehost2.
In this case, the warning pop-up suggests that the SSH connection to the source server was refused.
FTP stands for File Transfer Protocol.SFTP stands for File Transfer Protocol.
