Prevent background task from being killed

I am writing a program that logs into another system via SSH using the libssh2 library. Once logged in, I execute a command using:

libssh2_channel_exec(sshchannel, command)

The command executes okay. However, once I close the channel the process running is killed. In my case, the command (executing a binary executable) will run for a long period of time and my program cannot wait for it to terminate. I've tried issuing the following commands all to the same result (the process is still killed upon closing the channel):

/path/myprog
nohup /path/myprog
nohup /path/myprog &
/path/myprog &; disown

Further, I've observed this behavior for both libssh and libssh2. Is there some option or command I am missing?

Solution

  • you can use the unix at command:

    echo "cmd" | at now
