100% Free Software (GPL v3)Defensive BASH Programming
Nov 14th, 2012 | Comments
Here is my Katas for creating BASH programs that work. Nothing is new here, but from my experience pepole like to abuse BASH, forget computer science and create a Big ball of mud from their programs.
Here I provide methods to defend your programs from braking, and keep the code tidy and clean.
Immutable global variables
Try to keep globals to minimum
UPPER_CASE naming
readonly decleration
Use globals to replace cryptic $0, $1, etc.
Globals I allways use in my programs:Use Bash Strict Mode (Unless You Love Debugging)
Let's start with the punchline. Your bash scripts will be more robust, reliable and maintainable if you start them like this:
#!/bin/bash
set -euo pipefail
IFS=$'\n\t'

Is BGP safe yet? No.
Border Gateway Protocol (BGP) is the postal service of the Internet. It’s responsible for looking at all of the available paths that data could travel and picking the best route.
Unfortunately, it isn’t secure, and there have been some major Internet disruptions as a result. But fortunately there is a way to make it secure.
ISPs and other major Internet players (Comcast, Sprint, Verizon, and others) would need to implement a certification system, called RPKI.

Shell script escape injection
echo -e '#!/bin/sh\n\necho "evil!"\nexit 0\n\033[2Aecho "Hello World!"\n' > script.sh
chmod a+x script.shThe resulting script.sh will then work on (has been tested on):

As we have seen in this article, terminal escape injections affect practically every modern operating system environment and they can be really nasty.
As infosec professionals, we should know about them and keep our guards up when it matters. Hopefully this article provided enough information to stay safe.
Please feel free to let us know in the comment section your thoughts.

Bash tips: Colors and formatting (ANSI/VT100 Control sequences)
The ANSI/VT100 terminals and terminal emulators are not just able to display black and white text ; they can display colors and formatted texts thanks to escape sequences.
Those sequences are composed of the Escape character (often represented by “^[” or “<Esc>”) followed by some other characters: “<Esc>[FormatCodem”.
In Bash, the <Esc> character can be obtained with the following syntaxes:
\e
\033
\x1BExamples:
Code (Bash) Preview
echo -e "\e[31mHello World\e[0m"Hello World
echo -e "\033[31mHello\e[0m World"Hello World
NOTE¹: The -e option of the echo command enable the parsing of the escape sequences.
NOTE²: The “\e[0m” sequence removes all attributes (formatting and colors). It can be a good idea to add it at the end of each colored text. ;)
NOTE³: The examples in this page are in Bash but the ANSI/VT100 escape sequences can be used in every programming languages.
