Talk:1654: Universal Install Script
A few comments:
- curl | sh is still a common way to install things like package managers. Until you have Homebrew, or pip (for older versions of Python that didn't bootstrap it), etc., you can't use a package manager to install it, so they usually give you a one-liner to download and run a shell script that installs the package manager. Of course this isn't an issue for linux distros (which, unlike OS X, come with a built-in package manager).
- Mac users probably only interact with Steam through its GUI, but on linux, running steamcmd is more common. And this command will install a game that's in your library but not downloaded yet.
- I don't know why _only_ apt gets a sudo, but for brew, and for typical installations of Python on a Mac, you don't want or need sudo; they encourage you to leave the relevant directory writable by your normal user account.
- This script only handles the popular package managers on OS X and current popular linux distros. No port for FreeBSD, no Choco for Windows, etc. In fact, if you try it on Windows, you should get an error message telling you that you've ruined the joke by trying to extend it.

Also, docker is a deployment tool for deploying isolated, complete applications. For example, instead of just installing the Python scripts to run your web server behind nginx, you'd deploy nginx, Python, the modules you need for each, the appropriate configurations, a variety of tools the server depends on, and your scripts all as one big hunk of stuff. The docker website probably explains it better. :) --188.8.131.52 10:50, 11 March 2016 (UTC)
He forgot the .git on the end of the git clone command.

Also, the TLD in the curl. And, the install script would probably be at /install.sh, and use sh not bash.
Sh is generally preferred in scripting anyway since it comes on all *nix systems by default. Bash is on a very large number of systems, but not all.
Apt-get should have the -y flag.
If installing a program, npm should be given the -g flag to install globally instead of just in this directory.
Most programs print errors (as would arise if a package did not exist) to the console even if they are run with an & to indicate it should not be attached to the session. In this case, it should be &>/dev/null.
The program as a whole ignores previous programs and continues anyway. If it was found in one package manager, it would be a a very bad idea to write over it with another package manager's copy. This is part of the point of the comic, as is noted in the title text, but it's still an error.
