choose which shell is aliased ash hush

alias是用来定义命令的别名的关键字。在这个问题中，要选择的是ash和hush之间的shell。

ash是一种轻量级的Unix shell，是Bourne shell的较小版本，常用于嵌入式系统和一些资源受限的设备。ash具有类似于Bourne shell的语法和功能，但是更加精简和高效。ash是基本的shell，没有提供与现代shell（如bash）中的高级功能和扩展性相当的功能。

hush是另一种轻量级的Unix shell，被设计为嵌入系统和资源受限设备上的最小shell。hush的目标是提供一个非常小巧但功能齐全的shell，以满足对资源极为敏感的环境的要求，同时提供大部分常见Unix shell的功能。

因此，根据对ash和hush的描述，我们可以初步判断：
- 如果对shell脚本的需求较低，系统资源很有限，且只需要基本的shell功能，则选择hush可能更合适，因为hush是更小、更简洁的shell。
- 如果需要更强大和扩展性更好的shell功能，或者对Unix shell的功能有更高的期望，同时系统资源还允许，则选择ash可能更合适。

当然，选择shell要根据具体的应用场景和需求来决定。总体来说，ash和hush都是轻量级的shell，在资源受限的环境中更为适用。

/// TODO: Checking aliases of the two variables at source and sink. For example: /// src instruction: actualRet = source(); /// snk instruction: sink(actualParm,...); /// return true if actualRet is aliased with any parameter at the snk node (e.g., via ander->alias(..,..)) bool TaintGraphTraversal::aliasCheck(const CallICFGNode *src, const CallICFGNode *snk) { }

这段代码中有一个TODO标记，表示这是需要完成的一个任务。具体来说，这个任务是检查源节点和汇节点中两个变量的别名关系。例如，源指令可能是 `actualRet = source();` ，汇指令可能是 `sink(actualParm,...);` ，如果 `actualRet` 与汇节点中的任何一个参数存在别名关系，则返回true。在实现这个任务时，需要使用 `ander->alias(..,..)` 函数进行别名检查。

Select year and sum of games_sold, aliased as total_games_sold; order results by total_games_sold descending -- Filter game_sales based on whether each year is in the list returned in the previous task -- Add a column showing total games_sold in each year to the table you created in the previous task.

Sure, I understand your question. However, it seems like you are asking for a SQL query and I am an AI language model, I don't have access to any database. But I can help you with the query itself, so here's the query you can use to achieve the desired results:

SELECT year, SUM(games_sold) AS total_games_sold
FROM game_sales
WHERE year IN (SELECT year FROM game_sales GROUP BY year ORDER BY SUM(games_sold) DESC)
GROUP BY year
ORDER BY total_games_sold DESC;

This query will first select the year and the sum of games sold for each year, aliasing the sum as 'total_games_sold'. It then filters the results based on whether each year is in the list returned in the previous task. Finally, it adds a column showing the total games sold in each year and orders the results by total games sold in descending order.
