Scp batch uploads files to multiple machines (upgraded version)

Upgrading the previous version, adding support for password input from the command line, and prompting those machines to upload successfully or fail at the same time is very difficult for O & M, in particular, when cdn o & M needs to upload a file to 1000 machines, it is very difficult to manually upload files one by one.

Upgrade the previous version, add support for password input from the command line, and add a prompt indicating that the upload is successful or failed.
It is very difficult for O & M to manage multiple machines at the same time. in particular, if cdn o & M needs to upload a file to 1000 machines, it is very difficult to manually upload files one by one, for this reason, I wrote a batch scp file to a small program on multiple machines.
CT is used:
In this program, keep CT is used to help automatically enter the scp password. keep CT is mainly used to turn programs requiring manual interaction into programs for automation. this batch deployment system for O & M and batch unattended installation, execute commands in batches to upload and download files in batches.
Modern Shell provides minimum control (start, stop, and so on) for the program, and leaves the interaction feature to the user. This means that you cannot run some programs without interaction, such as passwd. Some programs can be run without interaction, but the flexibility is largely lost, such as fsck. This indicates that the construction logic of Unix tools is starting to have problems. CT just fills in some of the cracks and solves some problems that have existed in the Unix environment for a long time.

 
Expect uses Tcl as the core language. In addition, CT can be used no matter whether the program is interactive or non-interactive.

Find a machine that can be connected to the machine to be uploaded and install the secondary CT (you can use the secondary CT command to test whether it has been installed)
Put scp_upload.sh, multi_scp_upload.sh, and scp. conf in the same directory and run multi_scp_upload.sh.
