Screen Command
 
  
  
 
The great advantage of the screen command group is that when your shell exits or shuts down, the service you perform does not matter, that is, we can open a set of services in screen without being affected by the disconnection of the terminal.
Screen-S test          -R test          -R pid           -ls              + a,d               + a,n              + a,c              #当在一个screen时, create a new form
  
 

   
  
 
   
SCP command
 
  
  
 
SCP local_file [email protected]_ip:remote_dir    #拷贝本地文件到远程机器上 SCP -R local_dir [email protected ]_ip:remote_dir  #拷贝本地整个文件夹到远程机器上
  
 

   
  
 
   
Package Installation Management Commands
 
  
  
 
If the package you want to install is called an app, note that the commands here usually require sudo or root privileges.
