This article is about the scp command.
The command scp is used to copy files across ssh connection. You can use scp to copy files from or to a remote host. Using ssh for data transfer provides the same authentication and same level of security as ssh.
usage examples
Examples:
PULL - Copy the file "foobar.txt" from a remote host to the local host
scp nicolep@remotehost.com:foobar.txt /usr/local/download
PUSH - Copy the file "foobar.txt" from the local host to a remote host
scp foobar.txt nicolep@remotehost.com:/usr/local/download
More examples:
Recursively copy entire directories. This will get all the web directories and sub-directories and copy to the local machine
scp -r bob@10.0.0.1:/home/httpd/html/* /home/httpd/html
The -r is the flag for recursive
Now to copy all files in the current working directory to a remote server web directory
scp * nicolep@10.0.0.9:/var/www/html
Copy a file from one remote host to another, neither file residing nor resulting on the current machine.
scp nicolep@serverone.com:/usr/local/download/foobar.txt nicolep@servertwo.com:/home/nicolep
spaces in file path
Backslashing alone doesn't do the job, you have to escape and black slash.
example:
scp nicolep@192.168.10.8:/mnt/public/download/OS\\\ ISO\\\ Images\\\ ALL/debian-8.7.1-i386-netinst.iso ./
installation
Red Hat Enterprise Linux, CentOS, Trustix
yum install openssh-clients
Debian or Ubuntu
apt-get install openssh-client
