To make a text file executable, you need to do the following:

Write the Script: Create a text file with your script content. Make sure it starts with the appropriate shebang line indicating the interpreter to use, such as #!/bin/bash for a Bash script.

Change File Permissions: You need to change the file permissions to allow execution. You can do this using the chmod command in the terminal.

Here’s how you can do it:

Let’s say your script file is named myscript.sh. Open a terminal and navigate to the directory where your script is located. Run the following command to change the permissions:

chmod +x myscript.sh
This command makes the file executable.

Run the Script: Now you can execute the script directly from the terminal by typing ./myscript.sh.
If you want to run it from anywhere without specifying the path, you can move it to a directory that is included in your PATH environment variable or add its directory to your PATH.
