This article mainly introduces the method of passing the password to the ssh/scp command in the bash script, which is very detailed and has a certain reference value. Interested friends must read it!

Sshspass is a very useful tool for running ssh authentication in non-interactive mode. With sshspass, the password of the ssh or scp command can be used without interaction, which helps to use the password in shell scripts. We recommend using key-based authentication instead of using it.

Install SSHPASS

For most of the latest operating systems, the sshpass package is available in the default package repository. You can install it on the system using the following command.

On Debian:

$sudo apt install sshpass

On CentOS:

$yum-- enablerepo = epel-y install sshpass

Use SSHPASS

Sshspass uses the sshspass environment variable to store user passwords. You need to first use the sshspass variable and password, and then use this command. Here is a simple shell script that uses sshspass.

Export SSHPASS=ry3AvbWO0oupYX9HCMzp0Axxsshpass-e scp testfile.csv user@example.com:/uploads/
