Instead of hardcoding password in a shell script, use SSH keys, its easier and secure.
$ scp -i ~/.ssh/id_rsa *.derp devops@myserver.org:/path/to/target/directory/
assuming your private key is at ~/.ssh/id_rsa and the files you want to send can be filtered with *.derp
To generate a public / private key pair :
$ ssh-keygen -t rsa
The above will generate 2 files, ~/.ssh/id_rsa (private key) and ~/.ssh/id_rsa.pub (public key)
To setup the SSH keys for usage (one time task) :
Copy the contents of ~/.ssh/id_rsa.pub and paste in a new line of ~devops/.ssh/authorized_keys in myserver.org server. If ~devops/.ssh/authorized_keys doesn’t exist, feel free to create it.
