The shell enters the required user name or password through EOF in the script

The landlord encountered a scene like this:

Execute a script locally, log on to the server, but the login server requires a password to implement the password manually in the script

The function of EOF can be achieved by:

ssh  [Email protected] 192.168. 1.110  << eofpasswordeof

This enables the server to be logged in the script.

If root permission is required in the server and sudo needs to enter a password, this is the time to do so:

sudo  chmod 777 Test << eofpasswordeof

A second example:

#/bin/Basshva=123"input a value:" va <<! EOF Echo $va

The value of this output is: Hello world!
