The Nessus Attack Scripting Language, usually referred to as NASL, is a scripting language that is used by vulnerability scanners like Nessus and OpenVAS.With NASL specific attacks can be automated, based on known vulnerabilities. Tens of thousands of plugins have been written in NASL for Nessus and OpenVAS. Files that are written in this language usually get the file extension .nasl.
Writing NASL Scripts As mentioned earlier, NASL is designed to be simple, convenient, modular, efficient, and safe. This section details the NASL programming framework and introduces some of the tools and techniques that are provided to help NASL meet those claims.This section provides a descriptive overview of NASL script syntax, written to help the reader write his or her own NASL scripts.

The description field should contain a paragraph or more describing what the script does.
NASL supplies the infrastructure to write network-based scripts without the need to implement the underlying protocols. As NASL does not need to compile, plugins can be run at once, and development is fast. After understanding these benefits, it should be an easy decision to write your next network-based script using NASL.
NASL is the Nessus Attack Scripting Language, a scripting language for the testing of vulnerabilities first developed in 1998. With inspiration from the C programming language, non-coders wishing to develop a vulnerability test may be better served by Nmap and its LUA based NSE (Nmap Scripting Engine) scripts.
Before learning how to write script in Linux, you need to know what are the script editors available in Linux that will be used to write the shell scripts. At the end of the post, you can decide which text editor you can use to write your own script. Script Editors for Linux: gedit.
In the last post, we talked about regular expressions and we saw how to use them in sed and awk for text processing, and we discussed before Linux sed command and awk command.During the series, we wrote small shell scripts, but we didn’t mix things up, I think we should take a small step further and write a useful shell script.
A spec script is a screenplay written with the speculation that a production company will make the script into a movie.

Here's how to write a spec script that could result in a movie deal for you.

NASL garantees you that a NASL script: will not send any packet to a host other than the target host will not execute any commands on your local system NASL is not a powerful scripting language. Its purpose is to make scripts that are security tests. So, do not expect to write a third generation web server in this language, nor a file.
