How to have Guile on Ubuntu interpret Scheme source file?

First of all this might be really basic thing but I do not know how to proceed. I have Guile 2.0.9 and Libctl 3.2.2 installed on my Ubuntu 14.04.1 64-bit LTS. My aim is to write a source file in Scheme then have it interpret by Guile so I do not spend too much time on the prompt trying to correct some minor errors(correcting errors on a file is much easier). How can I have it read and execute the contents of my source file?

If you want to run .scm source file as a command line program you have to add at the head of your file:

#!/usr/bin/guile -s
!#

where you must specify proper path to you guile executable. You can find location of guile by

which guile

and you will get something like /usr/bin/guile

And do not forget to make you file executable:

chmode +x file.scm

If you want to set particular entry point to your program than there is another way to start script file:

#!/usr/bin/guile \
-e main -s
!#

-e option specify a program entry point function name.

For example file.scm

#!/usr/bin/guile \
-e main -s
!#
(define (main args)
    (display "Hello ")
    (write (cdr args))
    (newline))

Now let run it

[root@tuxbox ~]# ./file.scm Jim
Hello ("Jim")

You will find that information in guile documentation.
