Scsh includes these notable features:

• Library support for list, character, and string manipulations;
• Regular expressions manipulation support using scheme regular expressions, a domain-specific language (DSL), or little languages, approach to the abilities;
• Strong networking support;
• High-level support for awk like scripts, integrated into the language as macros;
• Abstractions supporting pseudo terminals;
• A shell language, modeled using quasi-quotation.

• Print a list of all the executables available in the current PATH to the standard output:

#!/usr/local/bin/scsh -s
!#

(define (executables dir)
  (with-cwd dir
    (filter file-executable? (directory-files dir #t))))
(define (writeln x) (display x) (newline))

(for-each writeln
  (append-map executables ((infix-splitter ":") (getenv "PATH"))))

The reference manual for Scsh includes a spoof Acknowledgments section^[2] written by Olin Shivers. It starts:

Who should I thank? My so-called "colleagues", who laugh at me behind my back, all the while becoming famous on my work? My worthless graduate students, whose computer skills appear to be limited to downloading bitmaps off of netnews? My parents, who are still waiting for me to quit "fooling around with computers," go to med school, and become a radiologist? My department chairman, a manager who gives one new insight into and sympathy for disgruntled postal workers?

and concludes with:

Oh, yes, the acknowledgements. I think not. I did it. I did it all, by myself.
