1. 2

    A comment fit for the “What are you working on this week?” thread, I am developing qwerty.sh as a curl-ready POSIX-portable shell program to download, verify, and unpack files with a single command (on Unix systems). The README includes examples.

    This provides an alternative to the ever-common curl ... | sh copy/paste installation instructions for developer tools, and I use it regularly as part of a workflow to have all projects go from a fresh clone to a fully integrated environment in a single-command repeatable build (e.g. with one-liners in a Makefile to download/verify/unpack external resources).

    I test qwerty.sh on Ubuntu GNU/Linux, Mac OS X, and FreeBSD.
