windows下特定字符搜索功能

news 2025/11/15 16:36:36

注：本人博客全部可读，并不收费。如若需要付费观看，与我本人无关。可能是系统收的钱。请不要误伤。

今天运行了一个好久不用的开发板，打印出了特定字符。这时候我忽然想找到它内部的程序，

那么该怎么找呢？

好在接触过内核，我知道在linux中可以通过命令行，配合指定的文件名找到。但是说实话，根据文件中包含的特定字符找文件这个操作，即使在内核中，我好像也没用过。

报着试一试的态度，搜了下，找到了这个帖子：

windows 查找目录下文件中包含某个字符串_windows查找文件中是否有字符串-CSDN博客

喜出望外啊，激动的我一试:

'E' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

FINDSTR: 写入错误

看来前博主是闭眼搬运。好在我也是bug王练出来的，会自己找答案。于是：

E:\> help findstr
在文件中寻找字符串。

FINDSTR [/B] [/E] [/L] [/R] [/S] [/I] [/X] [/V] [/N] [/M] [/O] [/P] [/F:file]
[/C:string] [/G:file] [/D:dir list] [/A:color attributes] [/OFF[LINE]]
strings [[drive:][path]filename[ ...]]

/B 在一行的开始配对模式。
/E 在一行的结尾配对模式。
/L 按字使用搜索字符串。
/R 将搜索字符串作为一般表达式使用。
/S 在当前目录和所有子目录中搜索
匹配文件。
/I 指定搜索不分大小写。
/X 打印完全匹配的行。
/V 只打印不包含匹配的行。
/N 在匹配的每行前打印行数。
/M 如果文件含有匹配项，只打印其文件名。
/O 在每个匹配行前打印字符偏移量。
/P 忽略有不可打印字符的文件。
/OFF[LINE] 不跳过带有脱机属性集的文件。
/A:attr 指定有十六进位数字的颜色属性。请见 "color /?"
/F:file 从指定文件读文件列表 (/ 代表控制台)。
/C:string 使用指定字符串作为文字搜索字符串。
/G:file 从指定的文件获得搜索字符串。 (/ 代表控制台)。
/D:dir 查找以分号为分隔符的目录列表
/Q:qflags 静音模式标志:
u 抑制对不支持的 Unicode 格式发出警告
strings 要查找的文字。
[drive:][path]filename
指定要查找的文件。

除非参数有 /C 前缀，请使用空格隔开搜索字符串。
例如: 'FINDSTR "hello there" x.y' 在文件 x.y 中寻找 "hello" 或
"there"。'FINDSTR /C:"hello there" x.y' 文件 x.y 寻找
"hello there"。

一般表达式的快速参考:
. 通配符: 任何字符
* 重复: 以前字符或类出现零或零以上次数
^ 行位置: 行的开始
$ 行位置: 行的终点
[class] 字符类: 任何在字符集中的字符
[^class] 补字符类: 任何不在字符集中的字符
[x-y] 范围: 在指定范围内的任何字符
\x Escape: 元字符 x 的文字用法
\<xyz 字位置: 字的开始
xyz\> 字位置: 字的结束

有关 FINDSTR 常见表达法的详细情况，请见联机命令
参考。
一番查询，我就知道上面那不适合我连基本命令都没整对。与是根据提示我找到了适合自己的搜索。

。。。（一下省略几百行吧）

这时候我正要说自己也不靠谱的时候，再认真阅读解释发现了这个，

“ 除非参数有 /C 前缀，请使用空格隔开搜索字符串。
例如: 'FINDSTR "hello there" x.y' 在文件 x.y 中寻找 "hello" 或
"there"。'FINDSTR /C:"hello there" x.y' 文件 x.y 寻找
"hello there"。

哦，不严谨的是我，因为有空格的参与，我的搜索句子被分割了。于是我留下了特定字符重新找：
