(Pass the-C flag to ssh to enable the compression function)-p retains the modification time, access time, and access permission of the original file. -Q: The transmission progress bar is not displayed. -R recursively copies the entire directory. -V details display output. Scp and ssh (1) will display the debugging information of the entire process. This information is used to debug connections, verify and configure problems. -C cipher encrypts data transmission with cipher. this option is passed directly to ssh. -F ssh_config specifies an alternative ssh configuration file, which is passed directly to ssh. -I identity_file: read the key file used for transmission from the specified file. this parameter is directly transmitted to ssh. -L limit: limits the bandwidth that a user can use, in Kbit/s. -O ssh_option if you are used to using the parameter transfer method in ssh_config (5),-P port should be written in uppercase, port is the port number used for data transmission-S program specifies the program used for encrypted transmission. This program must be able to understand the options of ssh (1. 4. example (copy files in directories and directories) (1) local> remote server: scp-r local-1-1-4-1/* 10.2.71.11: /data/www.test.com/(2) remote server-> local: scp-r 10.2.71.11:/data/www.test.com/* local-1-1-4-2
