This package is very useful. I use it to run youtube-dl and attach to my irssi container. I do lots from irssi/termux; tweet slack irc. The termux-url handler is great as well. You can process shared urls from your browser based on their domain name. For some urls I pass them to youtube-dl for others I push to getpocket and a couple of other special cases I have as well. My tablet wouldn't be the same without it.
