Lisp and shell commands

[gusl]

(run-program "/bin/sh" '("ls"))

source: 1

Now I just have to figure out how to get the output into Lisp.

(sb-ext:run-program "/bin/ls" '() :output *standard-output*)

will print the contents of the current directory into my SBCL shell, but it still returns # < SB-IMPL::PROCESS 28608 :EXITED > .

Since this stuff is implementation-specific, I don't know the right place to search for documentation.


A-ha!

(with-output-to-string (s) (sb-ext:run-program "/bin/ls" '() :output s))

returns the output of ls! Exactly what I wanted!

Now I just need the Lisp equivalent of Perl's split();

I can do almost anything with 'command-output'. One thing I cannot do is CDing. For that, I need 'chdir'. Any idea why?

chdir

There is no standard, portable chdir in ANSI CL. The rough equivalent of the current directory is (truename *default-pathname-defaults*).

Every common-lisp implementation has its own chdir, though, and there probably exist abstraction packages that provide it on multiple platforms. Check the Cliki, ask on #lisp.
