SCP Example Syntax


Secure copy or SCP is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. “SCP” commonly refers to the: Secure Copy Protocol. ref wiki.


Copy the file “sample.txt” from a remote host to the local host

$ scp /some/local/directory

Copy the file “sample.txt” from the local host to a remote host

$ scp sample.txt

Copy the directory “hanief” from the local host to a remote host’s directory “new”

$ scp -r

Copy the file “sample.txt” from remote host “” to remote host “”

$ scp \

Copying the files “sample1.txt” and “sample2.txt” from the local host to your home directory on the remote host

$ scp sample1.txt sample2.txt

Copy the file “sample.txt” from the local host to a remote host using port 2264

$ scp -P 2264 sample.txt

Copy multiple files from the remote host to your current directory on the local host

$ scp\{a,b,c\} .
$ scp\{sample1.txt,sample2.txt\} .

scp Performance

By default scp uses the Triple-DES cipher to encrypt the data being sent. Using the Blowfish cipher has been shown to increase speed. This can be done by using option -c blowfish in the command line.

$ scp -c blowfish some_file

It is often suggested that the -C option for compression should also be used to increase speed. The effect of compression, however, will only significantly increase speed if your connection is very slow. Otherwise it may just be adding extra burden to the CPU. An example of using blowfish and compression:

$ scp -c blowfish -C local_file
