simple script to download latest public releases of other github repos

fzf, curl, wget

• first you need to provide the source:
  -u | --url [github url]

• alternatively, you can use -o and -r:
  -o | --owner [repo owner]
-r | --repo [repo name]

• specifying the release file/format type is not required, but will make the download process automatable. it should be as specific as possible:
  -f | --file [file type/keyword]

• download directory is $pwd (current working directory) by default, but can be changed to move the output to a preexisting folder:
  -d | --dir | --directory [directory]

• force download of files even if the name has been cached before in the history file: -F | --force

• display help
  -h | --help

ask which version to download to ~/Downloads:
github-grubber.sh -u https://github.com/th-ch/youtube-music -d ~/Downloads

automatically download the tarball to $pwd:
github-grubber.sh -o th-ch -r youtube-music -f tarball

automatically download the amd64.deb package to ~/Desktop/folder:
github-grubber.sh -u https://github.com/th-ch/youtube-music -f amd64.deb -d ~/Desktop/folder
note: if ~/Desktop/folder does not exist, the script will not create the dir, rather it will leave the file in $pwd
