Penetration Testing with the Bash shell

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "The [FILE] or [DIRECTORY] argument would be any path or file you wish to fire ls at."

A block of code is set as follows:

#!/bin/bash
HOST=$1
SSL_PORT=$2
KEY_LEN_LIMIT=$3
VULN_SUIT_LIST=$4
echo -e "[*] assessing host \e[3;36m $HOST:$SSL_PORT\e[0m"
for cipher in `sslyze --regular $HOST:$SSL_PORT | awk -F\  '/[0-9]* bits/ { print $1"_"$2"_"$3 }'`

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\n\$' ...
