How to change the interpreter?

To change the interpreter for a script, follow these steps:

1. Open the Script: Use a text editor to open your script file (e.g., script.sh).

2. Edit the Shebang Line: Change the first line (the shebang line) to specify the desired interpreter. For example:

   • For Bash: #!/bin/bash
   • For Python: #!/usr/bin/env python3
   • For Perl: #!/usr/bin/perl
   • For Ruby: #!/usr/bin/env ruby

3. Save the Changes: Save the file after editing.

4. Make the Script Executable (if not already done): Run the following command in the terminal:

   chmod +x script.sh

5. Run the Script: Execute the script directly:

   ./script.sh

By changing the shebang line, you specify which interpreter should be used to run the script.
