| Ausführliche Beschreibung | Scsh has a high-level process notation for doing shell-script like
tasks: running programs, establishing pipelines and I/O redirection.
Scsh embeds this process notation within a full implementation of
Scheme, a minimal and clean dialect of the Lisp programming language.
The process notation is realized as a set of macro definitions, and
is carefully designed to allow full integration with standard Scheme
code. Scsh isn't Scheme-like; it is Scheme.
.
At the scripting level, scsh also has an Awk design, also implemented
as a macro that can be embedded inside general Scheme code.
.
Scsh additionally provides the low-level access to the operating
system normally associated with C. The current release provides full
access to POSIX, plus important non-POSIX extensions, such as
complete sockets support. "Full access to POSIX" means: fork, exec &
wait, sockets, full read, write, open & close, seek & tell, complete
file-system access, including stat, chmod/chgrp/chown, symlink, FIFO
& directory access, tty & pty support, file locking, pipes, select,
file-name pattern-matching, time & date, environment variables,
signal handlers, and more.
