I am working on a shell script performing recurring tasks of

  • git commit
  • git push
  • mvn release:prepare
  • mvn release:perform

in a couple of paths of a JAVA software project.

Now each of these commands asks for my rsa token password at least once, sometimes even multiple times: "Enter passphrase for key /..../.ssh/id_rsa:"

Is there a way to get around this? It would be OK if I had to enter the password once per script execution.

One boundary condition: I cannot use "spawn, expect, send"

A complication: I run the script in a CENTOS7 shell which is called on a windows10 machine via X-Win32. I would not like to log on to the native Linux Desktop environment.

Note: this is a copy of the same question which I posted in askubuntu - which was an off topic (https://askubuntu.com/questions/1178707/how-to-avoid-neccessity-to-re-enter-password-during-schell-script-execution)

Use ssh-agent.

It's quite possible that you already have it running on your system. Try adding your key to the agent using this command:

ssh-add

If ssh-agent is not running you will get the following message:
"Could not open a connection to your authentication agent."

To fix that use:

eval $(ssh-agent)

Then run the ssh-add command again.

Here is the ssh agent manpage.
