What is Secure Copy?<\/p>\n
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.
\nExamples
\nCopy the file “foobar.txt” from a remote host to the local host<\/p>\n
scp your_username@remotehost.edu:foobar.txt \/some\/local\/directory<\/code><\/pre>\nCopy the file “foobar.txt” from the local host to a remote host<\/p>\n
scp foobar.txt your_username@remotehost.edu:\/some\/remote\/directory<\/code><\/pre>\nCopy the directory “foo” from the local host to a remote host’s directory “bar”<\/p>\n
scp -r foo your_username@remotehost.edu:\/some\/remote\/directory\/bar<\/code><\/pre>\nCopy the file “foobar.txt” from remote host “rh1.edu” to remote host “rh2.edu”<\/p>\n
scp your_username@rh1.edu:\/some\/remote\/directory\/foobar.txt \n\\your_username@rh2.edu:\/some\/remote\/directory\/ <\/code><\/pre>\nCopying the files “foo.txt” and “bar.txt” from the local host to your home directory on the remote host<\/p>\n
scp foo.txt bar.txt your_username@remotehost.edu:~ <\/code><\/pre>\nCopy multiple files from the remote host to your current directory on the local host<\/p>\n
scp your_username@remotehost.edu:\/some\/remote\/directory\/\\{a,b,c\\} . <\/code><\/pre>\nscp your_username@remotehost.edu:~\/\\{foo.txt,bar.txt\\} . <\/code><\/pre>\nscp Performance <\/p>\n
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.<\/p>\n
scp -c blowfish some_file your_username@remotehost.edu:~ <\/code><\/pre>\nIt 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:<\/p>\n
