Configure Development Environment

Introduction

You've just joined a new software development team at TechCorp. The team uses a specific development environment setup, and you need to configure your system accordingly. This challenge will test your ability to work with environment variables in Linux, a crucial skill for any developer or system administrator.

TechCorp Development Environment

TechCorp uses a custom script called devtool for their development workflow. This tool needs to be accessible from anywhere in the system. Additionally, the team uses a specific configuration file that needs to be referenced by an environment variable.

Tasks

1. Create a directory named techcorp_tools in your home directory.
2. Create a simple bash script named devtool in the techcorp_tools directory that prints "TechCorp DevTool v1.0" when executed.
3. Make the devtool script executable.
4. Add the techcorp_tools directory to your PATH so that devtool can be run from anywhere. Immediately apply this change to your current session.
5. Append the export command to .zshrc to set up this environment variable permanently.
6. Create a file named techcorp_config.json in your home directory with the content: {"env": "development"}.
7. Create an environment variable named TECHCORP_CONFIG that points to the full path of the techcorp_config.json file.
8. Make sure the TECHCORP_CONFIG environment variable is available in all new shell sessions.

Hints

• Remember to use export when setting environment variables.
• Don't forget to make your script executable with chmod.
• Use $HOME or ~ to refer to your home directory when setting paths.
• source ~/.zshrc reloads the .zshrc file.

Example

After completing the tasks, you should be able to run the following commands from any directory:

$ devtool
TechCorp DevTool v1.0

$ echo $TECHCORP_CONFIG
/home/labex/techcorp_config.json

Summary

Congratulations! You've successfully configured your development environment according to TechCorp's specifications. You've demonstrated your ability to:

1. Create and modify directories and files
2. Write and make executable a simple bash script
3. Modify the PATH environment variable
4. Create custom environment variables
5. Make environment changes permanent

These skills are crucial for setting up and maintaining development environments, and will serve you well in your role at TechCorp and in your future career as a developer or system administrator.
