Notice also that other script interpreters aren't happy about CR line
endings:
$ cat > x.sh
#!/bin/bash
echo hello
Now change the LF to CR and get
$ ./x.sh
bash: ./x.sh: /bin/bash^M: bad interpreter: No such file or directory
or (if you add a space)
$ ./x.sh
echo hello: No such file or directory
$ bash -v ./x.sh
echo hello
(overprinting is involved in the last one).
