Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The msfdb command allows you to manage the Metasploit Framework database, not just initialize the database."

A block of code is set as follows:

print_status psh_exec(script)
print_good 'Finished!'

Any command-line input or output is written as follows:

root@kali:~# systemctl start postgresql

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select the Kali Linux virtual machine and click on Settings."
