Does anyone know why the following script works?
#a-random-junk-string
echo HI
The shell executes the echo command, and outputs HI. I thought that since there is no “!” after the “#”, the shell would give an error.
If there is no #! specifying a specific interpreter, the kernel will not intercept and launch it with the specified program.
However, the current shell may still interpret it as a command file, which is what you are seeing take place.
