为此，执行后面带该用户登录名的波浪号命令，如清单14所示。

To do this, just use tilde followed by the user's login name, as Listing 14 shows.

可以在波浪号前面输入一个数字，表示希望改变多少个字母字符的大小写。

You can enter a numeric character prior to the tilde to denote how many alpha characters you want to change.

文件检查发生在check函数中，仅简单地检查以波浪号（~）或者井号（#）结束的文件，以井号后开始或扩展名 .pyc 结束的文件。

File checking occurs in the check function and simply looks for files ending with a tilde (~) or pound sign (#), beginning with a pound sign, or ending with the extension .pyc.

波浪此起彼伏。

Waves rise and fall.

我们注视着波浪涌向海滩。

We watched the waves rolling onto the beach.
