- shell - How does the #! shebang work? - Stack Overflow
bin sh then starts reading the file's contents and discovers the shebang (#!) right at the very beginning of the file To the shell, this is a token ("magic number") by which it knows that the file contains a script Now, how does it know which programming language the script is written it?
- What is the preferred Bash shebang (#!)? - Stack Overflow
Using a shebang line to invoke the appropriate interpreter is not just for BASH You can use the shebang for any interpreted language on your system such as Perl, Python, PHP (CLI) and many others
- Why is shebang called shebang? - Unix Linux Stack Exchange
The name shebang for the distinctive two characters comes from an inexact contraction of SHArp bang or haSH bang, referring to the two typical Unix names for them Another theory on the sh in shebang is that it is from the default shell sh, usually invoked with shebang [18] [19] This usage was current by December 1987, [20] and probably earlier
- shebang - Why is #! usr bin env bash superior to #! bin bash? - Stack . . .
In addition to @zigg's answer, env may not be located at usr bin Shebang comments are altogether a bad idea IMHO If your default script interpreter doesn't handle shebang comments, it is just a comment However, if you know the script interpreter can handle shebang comments, and you know the path to bash, there is no reason not to invoke it using its absolute path unless the path is too

Put a shebang into a Python script to indicate: this module can be run as a script whether it can be run only on python2, python3 or is it Python 2 3 compatible on POSIX, it is necessary if you want to run the script directly without invoking python executable explicitly Are these equally portable?
- Multiple arguments in shebang - Unix Linux Stack Exchange
4 On Linux, the shebang isn't very flexible; according to multiple answers (Stephen Kitt's answer and Jörg W Mittag's), there is no designated way to pass multiple arguments in a shebang line I'm not sure if it will be of use to anyone, but I've written a short script to implement the lacking feature
