Do not manually enter a password when implementing the SCP file in a shell script using expect

The script is as follows:

#!/usr/bin/expect-f

Set Password Password

Spawn SCP username @ Target Machine IP: Path of the copy file location of local files
Set Timeout 300
Expect "user name @ Target machine IP ' password:" #注意: "User name @ Target machine IP" Here is consistent with the above
Set Timeout 300
Send "$password/R"
Set Timeout 300
Send "EXIT/R"

Expect EOF

Attachment: SCP Parameters
-r: Copy directory
-C: Allow compression

A complete example

#!/usr/bin/expect-f
Set Password 123456
#download
