Shortcuts automation
Create shortcuts to speed up tasks you do often. Searching for *ShellFish* in the Shortcuts app lists every available action.
Available actions include Upload, Download, List Directory, Run Command, Get Path, Stat File, Create Directory, Move, Delete, Backup, and Start Terminal. They take input from previous actions, so a shortcut can pass photos to Upload, run a remote command, or list a directory and process each entry.
When Download or List Directory finish they emit output that subsequent actions can use, so a shortcut can chain shell work and local processing arbitrarily.
Shortcuts can be triggered with voice via Siri.
