Can I bypass yes-or-no question while resetting tracker

  • 772

I want to make a desktop shortcut to reset the tracker using tracker-reset -e. It shows a yes or no question every time. Can I bypass it?

command-line tracker

2 Answers

  1. yes

    From coreutils package. man page:

    yes - output a string repeatedly until killed

    yes [STRING]...

    Repeatedly output a line with all specified STRING(s), or 'y'.

    So in your case would be:

    yes | tracker reset -e

  2. Best Answer

    You can, in general, "echo" an answer to the command, as in

    echo y | tracker reset -e

    which indeed will automatically provide the answer "y" to the prompt.

    If a terminal application requests more prompts, you could supply multiple answers as in

    printf '%s\n%s\n%s\n' y 1 q | terminalprogram

    In this hypothetical example, the first prompt of program terminalprogram is answered with y, then with a 1, then with q. The same effect could be achieved by including each answer on a new line in a text file answers.txt and then feeding the contents of the file to the program, as in

    cat answers.txt | terminalprogram

    or as in

    terminalprogram < answers.txt
