[LINUX] -bash: ./ {file name} .sh: /usr/bin/bash: bad interpreter: No such file or directory

When I created a shell script for the first time and executed it, an error occurred, so make a note.

Created shell script

Create a script file.

$ touch script.sh

The script I was creating is below. A simple script that just displays Hello.

#!/usr/bin/bash
echo Hello

Run

When executed,

$ ./script.sh

I get an error

-bash: ./script.sh: /usr/bin/bash: bad interpreter: No such file or directory

approach

Check which bash you are using because the specified bash is different. What was used here was / bin / bash.

$ which bash
/bin/bash

I was able to execute it by modifying the contents of the script as follows.

#!/bin/bash
echo Hello

I'm a beginner and I don't understand it in the first article, but for the time being. Please let me know if you make a mistake.
