Overview
The #! sequence of characters at the beginning of a file indicates that the file is a script: a set of commands to be fed into an interpreter. The path that follows #! is the path to the program that interprets the commands in the script, whether it be a shell, a programming language, or a utility. The interpreter executes the commands in the script, starting with the line following the #! line:
#! <interpreter> [optional-args]
Bash
#!/usr/bin/env bash
echo "."
