    Free program from terminal via ssh

    I am running a program on a "supercomputer" in my department via ssh.

    The program is currently giving a progress output to my terminal.

    I want to close my terminal, and log off, without stopping the program on the remote computer.

    I have tried typing & and pressing enter but that didn't do anything.

    I'm tempted to just close the terminal, but the program has been running for 2 days (I gave it a lot of data to crunch) and I don't want to lose these last 2 days of work.

    I apologize for the very dumb question.

    Thankyou

    If it helps, my terminal runs BASH and the remote machine uses TCSH

    Use whatever OS or desktop works for you. Dual boot or use VMs if you want. Backup your computer regularly, and definitely before upgrading, partitioning, or installing an OS.

    No support requests by PM please.

    You may or may not be able to background (Ctrl-Z, then enter "bg") and detach the process ("disown -h %[jobid]" when using bash, you'll have to look up the tcsh job control syntax). In the future just use screen for tasks like this.

    Use screen in future

    start screen then your program then press Ctrl-A D to detach it.

    then you can log out and leave it running

    next time you log on type

    Code:
    screen -r
    You can send a job to the background but if you logout it will kill it.

    You might be able to somehow save the process to a file then resume it inside screen but I wouldn't know how.
