Jenkins SSH & sshCommand (5 stars) (simple)

In Jenkins have code and SSH and sshCommand (gitlab is working fine, not worried about those keys) \really should be quick and easy here Got my keys and all should be fine but have sections working fine and others perhaps syntax issues. Can share my Jenkinsfile and perhaps we can do desktop share? using private / public key - (using withCredentials) got all 3 working when a "friend" used putty to export RSA ? I am on mac / linux - how can I do this? What is my solution to roll this out to many Targets? Doing a training and wants be to add "Execute shell script on remote host using ssh" However, the host can not be added as "SSH hosts is not available in Manage Jenkins? Any thoughts? Let me know your thoughts and any questions While this is hourly; there is a max of $10 that I can pay, as being a cancer patient is tuff and been out of work. Hourly will give you more $ as there is less money taken between us from freelancer - There is hope you can give your “best” price; unemployed, and have cancer with bills backing up, $10 possible? Glowing paragraph of feedback 5 stars My funds are low but will pay quick and leave 5 stars. Please give your best possible for your bid ? (something reasonable?) Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Look at feedback on my profile, feedback I left for many others. Here is the project: SINCERELY WOULD BE NICE TO MEET YOU PLEASE ANY THOUGHTS ? Please note project is due in two hours as this projects deadline, as this is needed if we can get some done - then we can talk about next steps and 5 stars and another job also. If this is a good one and we are "successful"; would need a couple others setup, but will handle one at a time? Can you do this for something reasonable in a couple hours? thoughts ?
