What is Secure Copy?

scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.

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 your_username@remotehost.edu:~

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 your_username@remotehost.edu:~

Копиране на файл "foobar.txt" от отдалечената машина на локалната: 

shell# scp your_username@remotehost.edu:foobar.txt /some/local/directory

Копиране на файл "foobar.txt" от локалната на отдалечената машина: 

shell# scp foobar.txt your_username@remotehost.edu:/some/remote/directory

Копиране на директория "foo" от локалната отдалечената машина в директория "bar" 

shell#$ scp -r foo your_username@remotehost.edu:/some/remote/directory/bar

Копиране на файл "foobar.txt" от машина "rh1.edu" на машина "rh2.edu" 

shell# scp your_username@rh1.edu:/some/remote/directory/foobar.txt your_username@rh2.edu:/some/remote/directory/


Копиране на няколко файла едновременно: 

shell$ scp foo.txt bar.txt your_username@remotehost.edu:~ 
shell$ scp your_username@remotehost.edu:~/\{foo.txt,bar.txt\} .
