[[Image:shebang.png|thumb|right|250px200px|The '''shebang line''' <u>must</u> appear on the '''first line''' and at the '''beginning''' of the shell script.]]If you are learning Bash scripting by reading other people’s code you might have noticed<br>that the first line in the scripts starts with the #! characters and the path to the Bash interpreter. This sequence of characters (#!) is called '''shebang''' and is used to tell the operating system which interpreter to use to parse the rest of the file.
