OpenCog shell
From OpenCog
This page describes how to run the OpenCog shell and what the various commands do (or points the reader to pages that describe each module/command in more detail). Examples for other subsystems, including the scheme shell, and a PLN example, can be found in the cookbook.
In this guide we will work from the source tree, since OpenCog hasn't yet reached the maturity to really have much use as system wide tool. We assume that the reader has created a compilation subdirectory in the root of the opencog source directory/branch called BIN_DIR.
To run the server, enter BIN_DIR (which you should be in already if you've just compiled everything):
./opencog/server/cogserver -c ../lib/opencog.conf
This loads the CogServer with the default OpenCog configuration.
The CogServer, by default, listens for telnet connections on port 17001. To connect, run:
telnet localhost 17001
You should be presented with:
Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. opencog>
