Make the ssh connection and enter the sudo password fully automatically
I want to make ssh connection automatically and install a packet to the connected machine. I'm able to process the SSH connection automatically. I can even run commands that do not require sudo authorization. But I didn't find a way to automatically enter the password in the commands that require sudo authorization. How do you think I can automatically enter the sudo password?
asd.sh
/usr/bin/expect -c 'spawn ssh -t usr@ip bash "pwd; sudo apt-get update"; expect "password:"; send "12345r"; interact;'
asd.sh output
spawn ssh -t usr@ip bash pwd; sudo apt-get update
usr@ip's password:
/bin/pwd: /bin/pwd: cannot execute binary file
[sudo] password for usr:
bash expect openssh pwd

"cannot execute binary file" is unrelated to your question. The command runs just fine, but fails for external reasons.

I know, I'm getting the print I want after I enter the sudo password. But I want to enter the sudo password automatically with the script and the result can be seen directly in the terminal. @tripleee

take a look at sexpect with which you can write Expect scripts with shell code only.

You need the -c argument to pass a command string to Bash. Also, try to have the pattern match the full line. Try with:
/usr/bin/expect -c 'spawn ssh -t usr@ip bash -c "pwd; sudo apt-get update"; expect "*password:"; send "12345r"; interact;'
^^ ^
Note that for this kind of task, Ansible can be very helpful as it will take care of all the boilerplate related to SSH and SUDO, and offers high-level modules to carry on any task easily.
The Ansible script ('playbook') would look like this (untested):
- hosts: ip
tasks:
- name: Update and upgrade apt packages
become: true
apt:
upgrade: yes
You can store the SUDO password in a file, and that file can be encrypted.
