They became power users, memorizing the letter commands and gloating over their knowledge of obscure functions.
这将返回到与您键入的第一个字母相匹配的第一个命令(以反向顺序)；随后键入的字母将使匹配变得越来越明确。
This goes back to the first command (in reverse order) that matches the first letter you typed; letters typed successively match more and more specifically.

注意，命令名以小写字母开头。
Notice that the name of the command begins with a lowercase character.
因此，整个脚本的输出通过sort、然后通过 uniq 进行管道传输，以产生在您的 $PATH 中找到的唯一命令的字母排序列表。
Therefore, the output of the entire script is piped through sort, and then uniq to yield an alphabetized list of unique commands found in your $PATH.
选项字母后的冒号(：)表示该选项需要一个值；例如，- f选项可能用于表示文件名，tar命令中就是如此。
A colon (:) after an option letter indicates that the option requires a value; for example, a -f option might be used to indicate a file name, as in the tar command.
要查看当前信号列表，使用 -l （字母l）命令。
To view the current list of signals, use kill -l (the letter l) command. The list is presented in the form (signal number, signal name)
在这个示例中，希望让getopt函数检查命令行中是否有任何选项字母，而且每个选项应该有一个值。
In this example, you want the getopt function to check for the existence of any of the option letters in that string, and each should have a value.
命令sort从指定文件中读取单词列表并按字母顺序进行排序。
The command sort reads a list of words from the named file and alphabetizes them.

在上面的命令序列中，把变量var设置为两字母的字符串ls。
In the sequence above, the variable var is set to the two-letter string ls.
运行rtdriver应用程序（传递给下面的命令的 -l标记是小写字母 l，不是数字1）
Run the rtdriver application (the -l flag passed to the following command is the lowercase letter l, not the digit 1)
例如，在最初的plot命令后面，其他plot命令选项都可以缩写，用选项的第一个字母表示。
For example, after the initial plot command, any further options to the plot command can be abbreviated, using the first letter of the option.
短形式字符串应该包含每个有效的选项字母，每个字母后面是一个冒号 (:)，这表示命令行选项后面应该是一个值。
The short form string should include each valid option letter, followed by a colon (:) to indicate that the command line option should be followed by a value.
当然，按字母顺序排列的命令列表对您也许没什么帮助。
Of course, an alphabetical list of commands may not be all that helpful.
以下命令输出三个7字符的密码并要求必须使用一个大写字母。
To print three passwords of 7 character length forcing the use of a capital letter use.
如果您不确定一个命令名的拼写，可以在输入几个字母之后按tab，就会看到可能的完整命令的列表，见图5。
If you're unsure of a command name, you can click Tab after typing a few letters to view a list of possible completions, as Figure 5 shows.
例如，图2说明如何通过管道连接find、grep和wc命令，从而寻找名称以小写字母 a开头的所有文件并统计其数量。
For example, Figure 2 shows how a find, grep, and wc command might be connected via pipes to find and count all files with names that begin with lowercase a.
我们以上一节结尾时创建的字母表集合为例，学习使用find命令：db . alphabet . find ；。
Let's start by using the find command on the alphabet collection we created at the end of the previous section: db.alphabet.find ;.
例如，命令aliasll'ls -hlt '将一个常用的命令行缩减为两个字母，从而使要输入和要记住的东西变得更少。
For example, creating alias ll 'ls -hlt' reduces a commonly used command line to just two letters-less to type and less to remember.
通过键盘，可以将英文字母、数字、标点符号输入到计算机中，因而可以向计算机发出命令。
Through a keyboard, English letters, Numbers and punctuation can be inputted into the computer, so keyboards can say the words.
创造新的程序语言包括字母分析、语法分析、产生底层命令、程序自动优化；
Syllabus:Create a new programming language including letter analysis, syntax analysis, generate low-level command and automatic optimization program;
本文除了可以识别语音命令外，还能够识别26个英文字母和一些简单的英文单词，并且把识别的结果显示在记事本的编辑区中。
Except recognizing speech command, the system can also recognize 26 English characters and some simple English letters, and make the result of recognition display on the screen.
