usage: dw [-h] [-f | -c] [-e] [-q] [-b] [-v] [--done DONE] [--left LEFT]
          [--current CURRENT] [--color-done COLOR_DONE]
          [--color-left COLOR_LEFT] [--color-current COLOR_CURRENT]
          [--icon-border ICON_BORDER]
          SOURCE [TARGET]

positional arguments:
  SOURCE                URL of the file
  TARGET                target filepath (existing directories will be treated
                        as the target location)

optional arguments:
  -h, --help            show this help message and exit
  -f, -o, --force       overwrite if the file already exists
  -c, --resume          resume failed or cancelled download (partial sanity
                        check)
  -e, --echo            print the filepath to stdout after downloading (other
                        output will be redirected to stderr)
  -q, --quiet           suppress filesize and progress info
  -b, --batch           Download files in batch. If this flag is passed the
                        passed source will be considered as a file with
                        download links seperated by a newline. This flag will
                        be ignored if source is a valid URL.
  -v, --version         show the program version number and exit

  --left LEFT           Icon indicating the percentage remaining to download

Other examples

In case you want to experiment with the progress bar's icons, here's some examples.

• This is when I passed icon_done as # and icon_left as space.

  

• In case a file's size is not available from the server, the progressbar is indefinite.
