推荐答案

主要区别是 FIND 用于使用过滤器搜索文件和目录，而 GREP 用于搜索文件内的模式或搜索过程

The Major difference is FIND is for searching files and directories using filters while GREP is for searching a pattern inside a file or searching process(es)

查找是使用大小，访问时间，修改时间等过滤器搜索文件和文件夹的命令。


find命令列出目录及其子目录中与一组过滤器匹配的所有文件。
此命令最常用于查找所有文件有一个特定的名称。

FIND is an command for searching file(s) and folder(s) using filters such as size , access time , modification time.
The find command lists all of the files within a directory and its sub-directories that match a set of filters.
This command is most commonly used to find all of the files that have a certain name.

要在当前目录及其所有子目录中找到所有名为theFile.txt的文件，请输入：

To find all of the files named theFile.txt in your current directory and all of its sub-directories, enter:

find . -name theFile.txt -print

要在当前目录及其子目录中查找所有以.txt扩展名结尾的文件，输入：

To look in your current directory and its sub-directories for all of the files that end in the extension .txt , enter:

find . -name "*.txt" -print

GREP ：（全局搜索

在文件中搜索指定的字符串或表达式。

Searches files for a specified string or expression.

Grep搜索包含以下内容的行指定的模式，默认情况下将其写入标准输出。

Grep searches for lines containing a specified pattern and, by default, writes them to the standard output.

grep myText theFile.txt

结果：Grep将打印出包含单词 myText 的每一行。

Result : Grep will print out each line contain the word myText.
