RAHUL.S (1NH12CS741) ANURAG (1NH12CS708) I ABSTRACT In this project ,we are designing a shell script which can be executed on Unix like OS platform such as Ubuntu ,Fedora etc with the aim of helping a novice user to setup and configure the environment and IDE and to repair any existing ones if necessary. We have designed a simple menu driven program which will help the user to go through this setup easily and without any hassle. At each step the program will ask the user to select the particular option listed and display and confirmatory message asking if he wishes to proceed further or abort the menu. This script will ask the user to pick his programming language and then it will check whether the environment for the picked language is setup properly or not. If the environment is not setup then it will automatically download the appropriate packages and it's dependencies from internet and install it and set different environment variables. This project is purely based on scripting and commands of Unix like OS.Most of the new or even experienced programmers of Java ,C, C++,etc don't have deep knowledge of these OS , so they find it hard to setup the appropriate environment for the programming language they prefer to code in.As a result they spend extra time to achieve this.All the programmers new or experienced can use this script and save their time.

In this usage, the term platform is a synonym. We often tend to think of environment as short for operating system environment , but, with the exception of UNIX -based operating systems, the operating system usually implies an underlying hardware microprocessor that the operating system is designed to run on. Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer. They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process. They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows also have included them as a feature, although with somewhat different syntax, usage and standard variable names. Examples of environment variables include: Path– a list of directory paths. When the user types a command without providing the full path, this list is checked to see whether it contains a path that leads to the command. Home (Unix-like) and USERPROFILE (Microsoft Windows) – indicate where a user's home directory is located in the file system. Temp – location where processes can store temporary files. Dept of CSE, NHCE 1 Environment Setup for PL 1.2 PROBLEM DEFINITION This script program will ask programmer to pick his programming language & then it will check whether the environment and its dependencies for the picked language is properly set up or not, if not set up then it will download the appropriate packages and its dependencies from internet and install it and set the different environment variables. 1.3 PROJECT PURPOSE The main objective of this project is to reduce the burden from the programmers both beginners and novice to set the programming environment for coding because he or she may not be knowing the methods and procedures to do so. This shell script can also be implemented in our college labs to keep a tab on the possible corruption of environment due to various reasons & check on the Integrated Development Environments (IDE) of various programming languages such as ECLIPSE for JAVA. 1.4 PROJECT FEATURES Our scheme was developed to reduce the computational overhead of the experienced programmer as well as to minimize the computational overhead of the rookie user. It uses one of the simplest forms of coding which is programming in shell script. Easier to learn and understand for beginners who are new to OS such as Ubuntu and Fedora. It is a simple and basic menu driven program. Has been designed in two different OS ie Fedora and Ubuntu. Has been implemented for programming langauges such as Java, Python,C,C++ . Dept of CSE, NHCE 2 Environment Setup for PL 1.5 MODULES DESCRIPTION 1.5.1 Setup and Configuration of the environment In this first and main module we have to setup the environment for the selected Programming Langauge under a particular UNIX like OS. In our program we will be setting up and configuring environments for the following programming langauges 1.JAVA 2.C Langauge 3.C++ 4.PYTHON 5.ANDROID. 1.5.2 Setup of Integrated Development Environment(IDE) This phase covers the downloading and installation of various IDE’s for various programming langauges. For example ,the user will be asked whether he wants to download and install Eclipse which Is the Integrated Development Environment for Java.. 1.5.3 Repair the environment & IDE In this module ,should there be any errors in the environment setup or in the installation of Integrated Development Environment ,we can detect these errors and repair them using the script.
