SCP (Secure Copy) is a command line tool for Linux systems to securely transfer files from local to remote server or vice a versa. SCP uses SSH protocol for transferring files between two systems which is more secure than ftp.
Syntax: (Local to Remote)
scp /path/to/local/file.txt email@example.com:/remote/path/
Syntax: (Remote to Local)
scp firstname.lastname@example.org:/remote/file.txt /path/to/local/
SCP command required password of remote system. In case you need to configure scp command in script and run with scheduler, you need to configure key based ssh login.
Transfer File Local to Remote Server
Following command will copy myfile.txt from current directory of local system to remote server’s /opt directory using root authentication. We are assuming remote server hostname is example.com.
$ scp myfile.txt email@example.com:/opt/
Transfer File Remote Server to Local
Following command will copy /opt/myfile.txt from remote system to local system’s /opt directory.
$ scp firstname.lastname@example.org:/opt/myfile.txt /opt/
Define Port with SCP Command
In case SSH is running on different port on remote server, use -P switch followed by port number with scp command.
$ scp -P 2344 myfile.txt email@example.com:/opt/myfile.txt
Transfer Directory Local to Remote Server Recursively
Following command will copy /opt/mydir directory from local system to remote system’s /opt directory recursively.
$ scp -r /opt/mydir firstname.lastname@example.org:/opt/
Transfer Directory Remote Server to Local Recursively
Following command will copy /opt/mydir directory from remote system to remote system’s /opt directory recursively.
$ scp -r email@example.com:/opt/mydir /opt/
