Introduction to the file transfer commands under Linux SZ RZ SFTP SCP.

secure ftp

It is a file transfer management tool based on SSH security protocol. Since it is based on SSH, it will encrypt the user's password, data and other sensitive information during transmission, so it can effectively prevent user information.

Stolen in the process of transmission, it has higher security than FTP. It is very similar to FTP in terms of functionality, not only can it transfer file data, but also can carry out remote file management (such as establishing, deleting, viewing files).

lists, etc.). Although there is only one word difference between SFTP and FTP, the transmission protocol based on which it is based is different. Therefore, you can't use the SFTP client to connect to the FTP server, and you can't use it.

FTP client to connect to the SFTP server.

Establish a connection: SFTP user@host

Upload a file from your local computer: put localpath

For local operations corresponding to the remote, you only need to add "l" before the command, which is easy to remember.

For example: lcd lpwd lmkdir

Secure Copy (Remote File Copy Program) is also a file transfer command based on the SSH security protocol. Unlike SFTP, it only provides file transfer between hosts, not file management.

Copy the local file to the remote directory directory.

scp local_file remote_user@host:remote_folder

Copy the local folder to the remote remote folder (with -r recursion).

scp –r local_folder remote_user@host:remote_folder

The above command is written in reverse, and the remote copy is made to the local computer.

sz rz is a command based on the zmodem transport protocol. The transmitted data will be verified, and the transmission performance is very good. It is very convenient to use, but the premise is that the window side needs to have a telnet or SSH client that can support Zmodem, such as SecureCRT.

Upload data to the remote: Run the rz be command, the client will pop up an upload window, and the user can select (you can select multiple files) to upload.
