What is the shebang line in shell scripting?

1.	What is the shebang line in shell scripting?
Answer» Shell scripts or programs often contain shebang at the top. In general, the Shebang (the SERIES of characters "#!") is used to indicate the operating system to use a particular interpreter to process the rest of the file. Here, the SYMBOL '#' is referred to as HASH, and "!" is referred to as bang. This usually aids developers in avoiding repetitive work. Scripts are generally executed by the engine; therefore, shebang DETERMINES the location of the engine that will be used to run the script. Example: #!/bin/bash In addition, this line also SPECIFIES which shell to use.
