That may be true in CL, but there is a scripting dialect of Lisp called TXR Lisp. It's documented in one big manual page (just like GNU Awk, Bash, and other classic programs). If you can't find what you're looking for there, either it doesn't exist, or you need help from StackOverflow or the TXR Mailing list.

TXR has decent capabilities for text processing, plenty of POSIX functions built right in, and such.

There is a decent port of TXR to Windows, which uses a fork of the Cygwin DLL called Cygnal. Cygnal provides more Windows-like behaviors in areas where stock Cygwin is too assertive with POSIX conventions in ways that make Cygwin programs confusing to Windows users.
