I take the privilege to present the print version for the Volume 1 Issue (1) of Journal of Advances in

Shell Programming. The intension of JoASP is to create an atmosphere that stimulates creativeness,

research and growth in the area of Shell Programming.

The development and growth of the mankind is the consequence of brilliant Research done by

eminent Scientists and Engineers in every field. JoASP provides an outlet for Research findings and

reviews in areas of Shell Programming found to be relevant for National and International recent

developments & research initiative.

The aim and scope of the Journal is to provide an academic medium and an important reference for

the advancement and dissemination of Research results that support high level learning, teaching and

research in the domain of Shell Programming.

Finally, I express my sincere gratitude and thanks to our Editorial/ Reviewer board and Authors for

An Approach to Design a Compiler in Context of Lexical

Analyzer (Scanner) and Parser Generation (Parser)

Followed by Non-optimized Intermediate Code

Generation using Compiler Construction Tools

Partha Ghosh*

Department of Computer Science & Engineering, Govt. College of Engineering

& Ceramic Technology, Kolkata, India

Abstract It is very tedious and lengthy task to write a compiler. To realize the various phases of compilers we can use some specific tools. These tools are called compiler construction

tools. Furthermore, we call it as compiler-compiler, compiler-generators, or translator

writing system. A mixture of compiler building tools are Scanner generator —it generates lexical analyzers. The patterns specified to these generators are in the type of regular

expressions. The LINUX has utility for a scanner generator called LEX. The specification

given to the LEX consists of regular expressions for representing various tokens. Parser generators — these produce the syntax analyzer. The specification given to these

generators is given in the form of CFG. Typically LINUX has a tool called YACC, which is a parser generator. Syntax-directed translation engines — in this tool the parse tree is

scanned fully to generate an intermediate code. The translation is done for each node of

the tree.

Keywords: Tokens, Lexeme, Lex, AST, Yacc

An Implementation of Extracting Data and Mining

Extracted Data from Web Pages

Abstract Web contains various information of particular object, which could be relevant as well as

non-relevant are called as data records. It is necessary to extract relevant information

from web pages. Web data extraction is the system which is used for extracting data from

various web pages. Data present on web pages are in un-structured format. In the

process of data extraction, we convert un-structured data into structured format. This

paper contains web data extraction system, stages of making a mashup and the data

mining concept for data clustering. Mashup is the process which provides functionality

such as data retrieval, data source modeling, data cleaning/filtering, data integration,

and data visualization. We use “Xtractorz” system for data extraction and mashup for

data records. By using data mining, we analyze data from different sources and using text

mining we cluster all the information. And we also use those data for providing value

added services

Keywords: Web, data, mashup, data clustering

Open Flow Network Visualization Software

Abstract Traditional IP network infrastructure is merely static, rather than flexible. Due to the

advent of Cloud technologies, future networks of machine-to-machine

(M2M)/Internet of Things (IoT) and the mobile devices generating Big Data, it has

become very difficult for network managers to configure and monitor the ever-

changing network dynamically. Recently, the concept of Software-Defined Network

(SDN), which allows us to administer and configure a network in a centralized and

programmable manner, has gathered network engineers’ and researchers’ attention

rapidly. OpenFlow has opened the door for network management in a more

controlled way. Though OpenFlow controllers provide a lot of raw data collected

from the underlying flows, it is still difficult for network managers to do analysis of

that Big Data and take better decisions for the network. This research aims to realize

a visualization software that facilitates the network managers to analyze the flow

data in a more user-friendly way. The proposed tool helps us to visually identify

selected flows from all lists of flows (i.e., Flowspace) and to monitor the status of

selected flows through application-specific interactive visual representations.
