When using the script, you must put the user or host combinations and the command into double quotes to ensure they are identified as a single argument.

在使用这个脚本时，您必须将用户或者主机组合和命令放到双引号中，以确保能够将其识别为单个参数。

If a variable contains whitespace, the double quotation marks keep the variable expansion intact as a single argument.

如果一个变量包含空格，双引号会按原样把变量展开为一个参数。

If the argument is zero, then the result will be -127 for a float and -1023 for a double.

如果参数为0，则对应的浮点数和双精度数的结果分别是- 127和- 1023。

Now this happens to be what we would call a linear process, because the number of times I go around the loop is directly related to the size of the argument. If I double 2 the argument, I'm going to double the number of times I go around the loop. If I increase it by five, 5 I'm going to increase by five the number of times I go around the loop.

这恰好是我们会成为,线性复杂度程序的一个例子,因为我要执行循环的次数是,和输入的参数的大小直接相关的,如果我将这个参数乘以,那么我就要将进行循环的次数也乘以2了，如果我把参数加上,那么循环的次数也要加上5了。
