struct HistoryLinkedList{
    head;
    tail;
    size;
    capacity;
}

historyAdd(&history, input) {
    // add the input line to the history
}

historyClear(&history) {
    // clear the history
}


// the main function should have the loop that processes all of the commands
main {
    while (true) {
        input = getInput;
        historyAdd(input)
        commands = getCommandsFromInput(input)
        execComamnds(commands);
    }
    return;
}

getInput() {
    // get the input from the user
}

getCommandsFromInput(input) {
    // return the list of commands from the input
}

execComamnds() {
    // execute the supplied commands

    When executing the commands I will allocate space
    for the pipes that I need and the children processes
    then after allocating them I will orchestrate the great
    magic of them working together
    
    This is a table describing the workflow
    
    read            ; process ; write

    stdin           ; cpid0   ; pipe[0][write]
    pipe[0][read]   ; cpid1   ; pipe[1][write]
    pipe[1][read]   ; cpid2   ; pipe[2][write]
    ...
    pipe[n-1][read] ; cpidn   ; stdout
