Summary Executable Permission: To run scripts as commands, they must have executable permission.
”#!/bin/sh”: The so-called she-bang instructs Unix which program to run to interpret and execute your code.
Bash scripts can be executed by invoking the bash interpreter explicitly, or by using the shebang and making the file executable.
C/C++ programs are executed as ‘binaries’ – the executable file contains binary data that instructs the shell how to start and execute the program.
Python can be coded as a script, like Matlab, or a program, like C/C++.<br>
