I try to execute a command that returns an error all the time (for example, I start copying a file, but during the recording process it stops or I begin to ping the server, but it does not respond). How to loop this process, so that the command is executed until it is completed with success (like "autodial")?

    It is much easier to just ignore the signal of loss of communication:

    nohup cp ./from ./to

      The easiest way is to execute the command in a loop and until the result of the command is without error

       #!/bin/bashuntil cp from to; do echo Ошибка, повтор через секунду sleep 1done

      Here from and to - non-existent files or files to which there is no access.
