Grab is a C++ program designed to automate the process of cloning a Git repository, building it using the 'make' command, and installing the resulting application. It does so within a temporary directory, ensuring a clean and isolated environment for the build process.

Before using Grab, make sure you have the following prerequisites installed on your system:

• C++ compiler
• Git
• Make

Follow these steps to use the Grab program:

1. Clone the repository containing this program to your local machine.

   git clone <repository_url>
   

2. Build the program.

   make
   make install
   

3. Execute the program with the desired Git repository path as a command-line argument.

   grab <repository_path>
   

   Replace <repository_path> with the path to the Git repository you want to clone, build, and install.

4. The program will perform the following steps:

   • Create a temporary directory in your system's temporary directory.
   • Clone the specified Git repository into the temporary directory.
   • Build the project using the 'make' command.
   • Install the application using 'make install.'
   • Clean up the temporary directory.

5. If any of the steps fail, the program will display an error message and exit with a non-zero status code.

6. If the installation process is successful, the program will display "Installation completed."

Here's an example of how to use the Grab program:

./grab myusername/my-repo

Replace myusername/my-repo with the actual Git repository path you want to build and install.

• This program assumes that the Git repository is accessible via SSH (using the [email protected] URL format). If you need to use HTTPS or a different Git URL, you can modify the 'git clone' command in the source code accordingly.
• Be cautious when running this program, as it involves executing shell commands. Ensure that you trust the repositories you are cloning and building.
