(print "Hello. World!")
At first, need compile this file:
:~$ sbcl --noinform
* (compile-file "helloworld.lisp" :output-file "helloworld")
; compiling file "/home/asimakov/helloworld.lisp" (written 04 FEB 2008 12:44:58 AM):
; compiling (PRINT "Hello. World!")
; /home/asimakov/helloworld.fasl written
; compilation finished in 0:00:00
#P"/home/asimakov/helloworld.fasl"
NIL
NIL
*
Next, load module binfmt_misc and mount binfmt_misc filesystem:
:~$ sudo modprobe binfmt_misc
:~$ sudo mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
At last, register fasl filetype (from root of course) by the specyfing a byte pattern:
:~$ echo ":lisp:M::\x23\x20FASL::/usr/lib/sbcl/sbcl-run:" > /proc/sys/fs/binfmt_misc/register
or by extension:
:~$ echo ':lisp:E::fasl::/usr/lib/sbcl/sbcl-run:' > /proc/sys/fs/binfmt_misc/register
That's all, you can execute fasl from command line:
:~$ chmod +x helloworld.fasl ; ./helloworld.fasl
"Hello. World!"
