20.3.2. Using the scp Command

The scp command can be used to transfer files between machines over a secure, encrypted connection. It is similar to rcp.

The general syntax to transfer a local file to a remote system is as follows:

scp <localfile>username@tohostname:<remotefile>

The <localfile> specifies the source including path to the file, such as /var/log/maillog. The <remotefile> specifies the destination, which can be a new filename such as /tmp/hostname-maillog. For the remote system, if you do not have a preceding /, the path will be relative to the home directory of username, typically /home/username/.

To transfer the local file shadowman to the home directory of your account on penguin.example.net, type the following at a shell prompt (replace username with your username):

 scp shadowman username@penguin.example.net:shadowman 

This will transfer the local file shadowman to /home/username/shadowman on penguin.example.net. Alternately, you can leave off the final shadowman in the scp command.

The general syntax to transfer a remote file to the local system is as follows:

scp username@tohostname:<remotefile><newlocalfile>

The <remotefile> specifies the source including path, and <newlocalfile> specifies the destination including path.

Multiple files can be specified as the source files. For example, to transfer the contents of the directory downloads/ to an existing directory called uploads/ on the remote machine penguin.example.net, type the following at a shell prompt:

 scp downloads/* username@penguin.example.net:uploads/
