try on your machine

This command utilizes both the echo and zenity commands in combination with piping and the sleep command.

Here is the breakdown of the command:

  1. The command echo is used to display the following text: "#1".
  2. The sleep command pauses the execution for 1 second.
  3. Another echo command displays the text "50".
  4. A second echo command displays the text "#2".
  5. Another sleep command pauses the execution for 1 second.
  6. A final echo command displays the text "100".
  7. The output of these echo commands is then piped using the | symbol to the zenity command.
  8. zenity --progress opens a progress dialog window using the Zenity tool.
  9. The piped output from the previous commands is fed into the progress dialog window, displaying a progress bar that changes based on the values echoed above.
  10. The progress dialog window remains open until all the commands have been executed and their output has been processed by Zenity.

In essence, this command displays a progress bar dialog using Zenity and updates the progress bar values with the numbers echoed within the command.
