    Another simple option utilizing the cat command:
    cat > /path/to/file
    Then hit Ctrl+D
    Voila, empty file.

    every trick using redirection “>” are the same !

    >file
    : >file
    true >file
    cat /dev/null >file
    my_prog >file (if my_prog produce no output)

    because the shell truncate (or create) “file” before launching the command (cat, true, …), the most important is that the command produces no output !!!

    you can understand that >file is the best one because it needs no other program !

      It is true, the basic idea is the use of the redirection mechanism. We are simply offering various alternatives that a user can choose to use, though they are more like the same.
