1. Create ~/icypc (directory in your home directory)
2. Make world readable/executable (chmod 755)
3. Create executable shell scripts in ~/icypc
   • ~/icypc/hunter
   • ~/icypc/planter
   • etc
4. Be sure to make them executable (again, chmod 755 will do it)
5. Register program(s) at ladder website: http://pc2.cs.purdue.edu:8000/ladder

A quick way to ensure that your icypc directory and all files are world-readable and (where appropriate) world-executable:

% chmod o+rX ~/icypc

Note that this command makes your source code readable, if it is in your icypc directory.

hunter

#!/bin/bash
cd /homes/YOUR-LOGIN-ID/icypc
/p/java-1.6/bin/java java_example.Hunter

camper

#!/bin/bash
cd /homes/YOUR-LOGIN-ID/icypc
c++_example/camper

Note that your script must be world-executable and all files needed by it must be world-readable. For example, you might set permissions like this…

% chmod -R o+rX /homes/YOUR-LOGIN-ID/icypc

This command recursively sets all permissions in your icypc directory to world (“o” for “other”) readable (“r”) and executable (“X”, which sets the execute bit only if on directories and files that are already exeuctable).

1. Use setup as above.
2. Example (with assumed student/player names)…

% java -jar icypc.jar -player pipe 1 /homes/li400/icypc/hunter -player pipe 1 /homes/wzhang/icypc/planter

There is an example “battle” script in /homes/jtk/icypc/battle, which takes four arguments:

% /homes/jtk/icypc/battle li400 hunter wzhang planter

Also, see the “hunter” and “camper” scripts in that directory for examples of running Java and C++ competitors. There is also a “twoer” script that uses a two hunter plus two planter strategy.
