Shebang is a # sign followed by an exclamation i.e. !. Generally, this can be seen at the beginning or top of the script/program. USUALLY, a developer uses this to AVOID repetitive work. Shebang mainly determines the location of the engine which is to be USED in order to execute the script.

Example: #!/bin/bash

The above line also tells which SHELL to use.
