Shell Sort

If you do this sort of thing often, you probably want to create a small shell script to automate this process just in case you have problems typing the Perl substitution command in the second line.

如果您经常做这类事情，可能想要创建一个小的shell脚本来自动化这一过程，以防在第二行键入替代的Perl命令时出问题。

A shell took off his father's head, and the baby was just left in the arms of his father, and this child has subsequently become sort of witless.

一颗炮弹炸掉了他爸爸的头，婴儿就留在爸爸的怀里，后来这孩子就变得有点愚笨。

In this case, since the program really does have to run in a shell anyway, it even sort of makes sense to do it this way.

这种情况下，由于该程序实际上不必在shell中运行，所以这样做比较合理。
