About

If you are willing to run a script - like the example i have provided - you can run "pandash scriptName" and for interactive mode just run "pandash". It is always listening for other pandas messages.

You can also communicate with other pandash shells using "pandash_talk" built-in command, it will take you to chat mode and you can start sending messages, just make sure your provided IDs are not identical. For example if your id is COOL and the other shell's ID is COOLER your should run "pandash_talk COOL COOLER" and the other shell must run "pandash_talk COOLER COOL" (you choose your ID by typing this command)!

More details

Each command you type to execute is handled by a child process and can be terminated using Cntrl+c. Piped commands are handled in the same manner but they exchange their stdin and stdout.

Named pipes, aka FIFO, is used for implementing communication functionality and a child process is responsible for handling "chat mode" so you can use Cntrl+c to exit from "chat mode".

Hope you enjoy! Use at your own risk :)
