This is just a suggestion to make it easier for Linux/Unix users to use the Gnu
compilers instead of having to use a scripting language for short little
utilities.
I know someone has created and released a binary C interpreter for this purpose.
But why would you want to install another program, if you could essentially use
the tools you already have.
I think gcc (and all the compilers) should support the "#!" in source files to
make something similar easily possible.
So one could write C or C++ (or Fortran, etc) code and just run the source file
to compile and run.
The Best way to make this possible is to set up the compiler to ignore "#!" if
it is the first line.
Maybe a special pre-processor would work as well, but it is nice if one can
send the unmodified source through the standard compilers (the edit and run
process is a quick way to try out ideas before creating a full program).
This could encourage people to do this more often (increasing the utility of
writing short compiled scripts) if one could do the below by simply starting
the source file with:
#! /usr/bin/compile-and-run-file.sh -v
Currently, to do this (with C and C++) one needs to start their code similar to
this (this works, I have tested it):
#if 0 /* (first line is blank on purpose)
# Warning, the following will usually be run by sh (not bash, nor
csh)
# If you make this file executable - it will be processed by the
script below.
compile-and-run-file.sh -v "${0}" "${@}"
exit
# End of C comment */
#endif
I have a complete example here (including the complile-and-run-file.sh script):

Note: I am not a very good C/C++ programmer, so I don't pretend to have the
best answer (this is just an example of one way to do this).
Thanks.
