node.js required to run the script

To make a JavaScript file executable as a global command in the Terminal on Linux/macOS, you can follow these steps:

1. Make the file executable: Open the Terminal and navigate to the directory where your JavaScript file is located. Use the chmod command to make the file executable:

   chmod +x index.js

2. Create a symlink to a directory in your PATH: To make your JavaScript file globally executable, you need to create a symbolic link (symlink) to it in a directory that is included in your system's PATH environment variable. Common locations for such global scripts include /usr/local/bin or ~/bin.

   For example, to create a symlink in /usr/local/bin, you can use the ln command:

   sudo ln -s /path/to/your/index.js /usr/local/bin/myScript

   Replace /path/to/your/index.js with the actual path to your JavaScript file and myScript with the desired command name you want to use in the Terminal.

3. Verify that it works: Now, you should be able to run your JavaScript file as a global command from the Terminal:

   myScript

   The Terminal should execute your JavaScript file using Node.js, and you'll see the output.

Remember that you need appropriate permissions to create symlinks in system directories like /usr/local/bin, so you may need to use sudo to execute the ln command with superuser privileges. Use caution when modifying system directories.

An example of the directory structure before and after merging two PDF files:

Before Merge (Directory Structure):

Suppose you have two PDF files named document1.pdf and document2.pdf located in a directory:

my-pdfs/
│
├── document1.pdf
│
└── document2.pdf

In this example, you have two separate PDF files that you want to merge into a single PDF file.

After Merge (Directory Structure):

After merging the two PDF files, you will have a new PDF file that contains the merged content. The directory structure may look like this:

my-pdfs/
│
├── document1.pdf
│
├── document2.pdf
│
└── merged_document.pdf

In this structure, merged_document.pdf is the newly created PDF file that contains the combined content of document1.pdf and document2.pdf. You would typically use a PDF merging tool or library to create this merged PDF file.
