In Linux system, we often create many automated scripts to help us handle all kinds of work. Today, I need to automatically log in to the remote server on a local host and execute commands on the server.
I thought it would be a little troublesome, but when I search it on Internet, it simply surpassed my imagination. The record is as follows.
ssh into the remote server and execute commands
First, we take a look for the command to log in remote server:
ssh user_name@remote_server_ipThen if you need to execute a command, you can use the following command to do it (for example: use ls command):
ssh user_name@remote_server_ip "ls"Output:
Is it convenient?
If you need to execute multiple instructions, you can use && to separate the instructions.
By the way, I have a problem in Vim editor:
ssh user_name@remote_server_ip "vim test.py"Output:
Vim: Warning: Output is not to a terminal
Vim: Warning: Input is not from a terminalAnd the bad thing is that I can’t even quit in the VIM editor. After checking on the Internet, I found out that if you need to be able to interact (including htop), you need to add the -t parameter.
ssh -t user_name@remote_server_ip "vim test.py"Output:
Sure enough, it was normal.
