Non-interactive modification of local user password __ Password modification

The latest server root password needs to be updated

Use the Saltstack deployment tool for bulk modification, so you cannot use an interactive method.

There are two ways of not interacting:

1. Use CHPASSWD

echo "test:1234" | chpasswd

2, the use of passwd can also be implemented non-interactive password modification

echo "1234" | passwd--stdin "Test"

Return output:

Changing password for user root.
Passwd:all authentication tokens updated successfully.
Both of these methods use a non-interactive way to modify the password for user test.
