Linux Shell (SSH bulk configuration secret) read the configuration file for remote operation

Requires the target machine to have the expect command installed

Divided into five files config.ini (config file), id_ras.pub (public key), read.sh (a function for reading the configuration file), test.sh (execution file), run.sh (remote run script) is a configuration file.

Step 1: Read the configuration file ip,user,pwd

Step 2: Id_rsa.pub, run.sh SCP to the remote machine

Step 3: Run the script remotely

read.sh
