Today, I will introduce to you how to use the Linux system commands scp and ssh. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.

If the port of ssh is 22, you don't have to specify the-p or-P options.

1.sshLinux uses the ssh command to log in to the server: ssh-l root-p 188 192.168.1.2ssh-l user name-p port number host name or IP enter the password

The 2.scpscp command copies a file or directory command:

Copy files: (1) copy local files to remote scp-P 22 file name user name @ computer IP or computer name: remote path scp-P 22 test.txt root@192.168.1.163:/opt/ (2) copy files back to local scp-P 22 user name @ computer IP or computer name: file name local path scp-P 22 root@192.168.1.163:/opt/test.txt / opt

Copy directory: (1) copy local directory to remote scp-r-P 22 directory name user name @ computer IP or computer name: remote path scp-r-P 22 / opt/test/ root@192.168.1.163:/opt/ (2) copy directory back to local scp-r-P 22 user name @ computer IP or computer name: directory name local path scp-r- P 22 root@192.168.1.163:/opt/test/ / opt/

3. Usage problem

If scp can be used on this machine, an error will be reported when scp uploads the file:

Bash: scp: command not found

Lost connection

Then the other party does not have the openssh-clients package installed.

4. After testing, in our company to use scp to upload files to the server, the speed reaches 500KB/S~900KB/S, if you use FlashFXP, the speed is only 40KB/S, powerful scp.
