Linux command--scp usage
There are three common methods for copying files between different Linuxes:
The first is ftp, that is, one of the Linux installations installs ftpServer, so that the other one can use the ftp client program to copy files. copy.
The second method is to use the samba service, which is similar to the Windows file copy method and is relatively simple and convenient.
The third method is to use the scp command to copy files. scp is a secure file copy, based on ssh login
Sometimes we need to obtain a file on a remote server. The server is neither configured with an ftp server nor shared. When the file cannot be obtained through conventional channels, Just use a simple scp command to achieve the goal.
1. Copy the local file to the remote server
Copy the local file news.txt to the /etc of the 192.168.6.129 machine (the user name is root) /squid directory
#scp /home/administrator/news.txtroot@192.168.6.129:/etc/squid
/home/administrator/ Absolute path to local file
News.txt Local files to be copied to the server
Root .6.129 The IP address of the remote server (you can also use the domain name or machine name) /etc/squid Copy the local file to the path located on the remote server
Pass The root user logs in to the remote server, enter yes to agree to establish the ssh connection
Prompts to enter the root user's password
Please use the -r parameter to copy the folder
2. Copy the files on the remote server to the local machine#scp root@192.168.6.129:/usr/local/sin.sh/home/administrator
root The root user logs in to the remote server
192.168.6.129 The ip of the remote server/usr/local/sin.sh The file on the remote server that you want to copy to this machine
/home/administrator Copy the remote file to the local absolute path Note two points:1. If the remote server firewall has special restrictions, scp You need to use a special port. The specific port to use depends on the situation. The command format is as follows: #scp-p 4588 remote@www.abc.com:/usr/local/sin.sh /home/administrator Available parameters - -v is used to display progress. Can be used to view connection, authentication, or configuration errors. -C enables compression options. -P Select the port. Note that -p has been used by rcp. -4 Force the use of IPV4 address. -6 Force the use of IPV6 address. -r Copy a folder2. When using scp, pay attention to whether the user you use has permission to read the corresponding files on the remote server.The above is the detailed content of Linux command--scp usage.
