Chapter 5
ASPL Scripting Language
The sheband #!/usr/bin/env is the trivial way to invoke the interpreter of a scriptiing language on the UNIX system. However, for more compatibility across various UNIX systems, an enhanced two-liners shebang entry has been added in ASPL: the first line invokes the interpreter through env, and the second line provides the arguments to be passed to the interpreter. Of course, if the aspl program is available in /usr/bin then you can always invoke the interpreter with the shebang #!/usr/bin/aspl (or wherever the interpreter has been installed, assuming the #! has not been disabled on your system). In addition, since the standard input can be piped to ASPL then one can use other scripting languages to invoke ASPL.
