You Have Been Hired By Tmi To Design An Application Using Shell Script

You have been hired by TMI to design an application using shell script programs. TMI Case Projects needs you to design and create a new directory structure. The company has several departments: accounting, sales, manufacturing, information technology, and headquarters. The accounting department has accounts receivable, accounts payable, and payroll functions within it. The manufacturing department runs three shifts and a weekend shift. The information technology department has five projects in progress. The sales department has offices located in the West, East, North, and South. First, design the Linux file system hierarchy on paper. Keep in mind that the departments, functions, shifts, regions, and projects need to translate into directories. Next, you need to create this hierarchy on the Linux system. Create at least one empty file in each directory. Use the department, function, shift, region, or project name as the filename and include an extension of .dat.

Design and Implement Directory Structure Using Shell Script for TMI

The task assigned by TMI requires a comprehensive understanding of Linux file system hierarchy and proficiency in shell scripting to automate the creation of a complex directory structure that reflects the company's organizational framework. This project encompasses designing a hierarchy that correctly categorizes departments, functions, shifts, regions, and projects, followed by scripting to generate these directories with specific files in each.

Designing the Directory Hierarchy

The first step involves planning the hierarchical architecture using paper or diagramming tools. This structure must be intuitive, scalable, and should mirror the company's organizational chart. The hierarchy begins with a root directory for the company, say /TMI. Under this, departmental directories such as accounting, sales, manufacturing, information_technology, and headquarters are created.

Within each department, subdirectories for functional units or project categories are established. For example, the accounting department contains accounts_receivable, accounts_payable, and payroll. The manufacturing department includes separate directories for shift1, shift2, shift3, and weekend_shift. The information_technology department has directories for each project, such as project1, project2, etc. The sales department has directories for each regional office: West, East, North, and South.

This hierarchical structure ensures easy navigation, management, and scalability. Once the hierarchy is finalized on paper, the implementation begins with shell scripting to automate directory creation.

Implementing the Directory Hierarchy with Shell Script

The core of this project lies in creating a shell script that automates the directory and file setup. Using bash scripting, commands like mkdir and touch will facilitate directory and file creation.

The script should perform the following tasks:

  • Define an array or list of all department names, functions, shifts, regions, and projects.
  • Iterate through these lists to generate directory paths in the hierarchy.
  • Create each directory using mkdir -p to avoid errors if directories already exist.
  • Within each directory, create at least one empty file named after the directory itself with a .dat extension, e.g., accounts_receivable.dat.

An example shell script snippet might look like this:

#!/bin/bash

Define main root directory


root="/TMI"


Create main directory


mkdir -p "$root"


Departments


departments=("accounting" "sales" "manufacturing" "information_technology" "headquarters")


for dept in "${departments[@]}"; do


mkdir -p "$root/$dept"


done


Accounting functions


accounting_functions=("accounts_receivable" "accounts_payable" "payroll")


for func in "${accounting_functions[@]}"; do


mkdir -p "$root/accounting/$func"


touch "$root/accounting/$func/$func.dat"


done


Manufacturing shifts


shifts=("shift1" "shift2" "shift3" "weekend_shift")


for shift in "${shifts[@]}"; do


mkdir -p "$root/manufacturing/$shift"


touch "$root/manufacturing/$shift/$shift.dat"


done


Logistics for sales regions


regions=("West" "East" "North" "South")


for region in "${regions[@]}"; do


mkdir -p "$root/sales/$region"


touch "$root/sales/$region/$region.dat"


done


Information Technology projects


projects=("project1" "project2" "project3" "project4" "project5")


for proj in "${projects[@]}"; do


mkdir -p "$root/information_technology/$proj"


touch "$root/information_technology/$proj/$proj.dat"


done

This script efficiently automates the creation of the entire hierarchy with minimal manual intervention, ensuring consistency and saving time. It can be extended or modified to include additional directory levels or files as needed. Proper execution of this script requires appropriate permissions.

Conclusion

This project demonstrates the application of shell scripting to automate complex directory structures that mirror real-world organizational setups. By carefully designing the hierarchy and scripting its creation, organizations can streamline setup processes, enforce standardization, and facilitate easier management of data and resources. The principles applied here are also transferable to other automation tasks within Linux environments, showcasing the importance of scripting skills for system administrators and developers alike.
