Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

set interfaces ethernet eth1 description WAN
set interfaces ethernet eth2 description WLAN

... my first disclosure. Man, it feels weird doing this.

update 6/6/16 I would like to stress something: I'm not saying "Don't buy an ASUS device" -- I see a lot of people who want to lambaste ASUS for this and boycott their hardware. This isn't what I want people to be doing by any stretch. Stupidly, I like the ASUS hardware I have (it's nice for the price) and I would rather see a pressure on ASUS as an OEM to stop shipping "value added software" to consumers; If you want to help Microsoft in pushing this mentality, go buy a signature machine from them. Microsoft provides support, but also only ships windows and a few select utilities that are essential to the functioning of the system (think: Radeon/Optimus and nVidia control panels) and fall heavily on the hardware makers (ATI, nVidia, Intel) to provide support for the harware.

Consider an ASUS device all you want. Start putting pressure on Microsoft that consumers want bloat-free devices and start voting with your money. Microsoft's store
