How to Specify the Script’s Interpreter for bash script

To specify the script’s interpreter for a Bash script, you can use the shebang line. The shebang line is the first line of the script and begins with #! (hashbang) followed by the path to the interpreter.

For example, to specify the Bash interpreter, you would include the following shebang line at the beginning of your script:

#!/bin/bash

Here’s how you can do it:

1. Create a new file and save it with a .sh extension. For example, myscript.sh.
2. Open the file in a text editor and write your Bash script within it.
3. Add the shebang line as the first line of the script, specifying the path to the Bash interpreter. In most Unix-like systems, the Bash interpreter is located at /bin/bash. So the shebang line would be:

#!/bin/bash

If your Bash interpreter is located in a different directory, you would specify that path instead.

4. Save the file.

5. Make the script executable using the chmod command. For example:

chmod +x myscript.sh

Run the script by typing its name preceded by ./ (dot slash), followed by Enter:

./myscript.sh

The script will execute using the specified interpreter (in this case, Bash).
