我的批处理文件应该将每个包含的整个短语输出到一个文本文件dog.
例如，假设输入文件是这样的：
dog.house, asdasd dog.dinner
dog.hello
结果应该是：
dog.house
dog.dinner
dog.hello
到目前为止，我的批处理文件是：
for /F "tokens=*" %%a in ('findstr /c condor. temp.txt') do echo %%a >> resultado.txt
但返回整行而不是包含“dog.”的短语。我无法理解批处理的工作原理。
是的，for循环很棘手。 for没有任何开关在一行上逐字解析。 for /f逐行循环，如果需要，使用标记作为单词。你需要的是两者的结合。
@echo off
for /f "delims=" %%I in ('findstr /i "dog\." temp.txt') do (
for %%a in (%%I) do (
echo %%a | findstr /i "dog\."
)
)
这会给你你期望的结果。
示例结果
C:\Users\me\Desktop>type temp.txt
dog.house, asdasd dog.dinner
dog.hello
C:\Users\me\Desktop>test.bat
dog.house
dog.dinner
dog.hello
您可以在 FOR 命令上使用一个很好的教程。我最喜欢的是http://judago.webs.com/batchforloops.htm
只要文件不包含*或?字符，rojo就有很好的解决方案。<space>FOR 循环在、<tab>、,、;和处断开“短语” =。这是一个稍微高效的版本，它通过 FINDSTR 的单次迭代管道所有“短语”。我还使用了神秘的语法来禁用 DELIMS 和 EOL，以保留以;.
@echo off
setlocal
cmd /c "for /f delims^=^ eol^= %%I in ('findstr /c:"dog." test.txt') do @for %%a in (%%I) do @echo %%a" | findstr /c:"dog." >resultado.txt
和限制可以通过放弃简单的 FOR 并使用搜索和替换来替代*，并通过 FINDSTR 回显结果来解决。有语法可以批量执行此操作。但这只会使解决方案变慢:(?<line feed>space
我怀疑速度提高是否足够。您可以按照 rojo 的建议下载和使用 grep，也可以切换到更好的脚本语言，如 VBScript、JScript 或 PowerShell。
编辑
有时您无法将可执行文件下载到机器上，并且您可能不习惯使用另一种脚本语言。
我编写了一个名为 REPL.BAT 的混合批处理/JScript 实用程序，它执行正则表达式搜索和替换。它适用于所有现代 Windows 机器，并且不需要任何安装过程。只要 REPL.BAT 在您当前的文件夹中，或者在您的 PATH 中的某个位置，那么下面的简单行就可以满足您的需求。它使用 REPL.BAT 将所有空格转换为换行符，然后将结果通过管道传输到 FINDSTR。这个解决方案应该很快。
repl.bat " " "\n" x <temp.txt | findstr /c:"dog." >resultado.txt
这是 REPL.BAT 实用程序。完整的文档嵌入在脚本中。

:::
:::REPL Search Replace [Options [SourceVar]]
:::REPL /?
:::
::: Performs a global search and replace operation on each line of input from
::: stdin and prints the result to stdout.
:::
::: Each parameter may be optionally enclosed by double quotes. The double
::: quotes are not considered part of the argument. The quotes are required
::: if the parameter contains a batch token delimiter like space, tab, comma,
::: semicolon. The quotes should also be used if the argument contains a
::: batch special character like &, |, etc. so that the special character
::: does not need to be escaped with ^.
:::
::: If called with a single argument of /? then prints help documentation
::: to stdout.
:::
::: Search - By default this is a case sensitive JScript (ECMA) regular
::: expression expressed as a string.
:::
::: JScript syntax documentation is available at
::: http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
::: Replace - By default this is the string to be used as a replacement for
::: each found search expression. Full support is provided for
::: substituion patterns available to the JScript replace method.
::: A $ literal can be escaped as $$. An empty replacement string
::: must be represented as "".
:::
::: Replace substitution pattern syntax is documented at
::: http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
::: Options - An optional string of characters used to alter the behavior
::: of REPL. The option characters are case insensitive, and may
::: appear in any order.
:::
::: I - Makes the search case-insensitive.
:::
::: L - The Search is treated as a string literal instead of a
::: regular expression. Also, all $ found in Replace are
::: treated as $ literals.
:::
::: E - Search and Replace represent the name of environment
::: variables that contain the respective values. An undefined
::: variable is treated as an empty string.
:::
::: M - Multi-line mode. The entire contents of stdin is read and
::: processed in one pass instead of line by line. ^ anchors
::: the beginning of a line and $ anchors the end of a line.
:::
::: X - Enables extended substitution pattern syntax with support
::: for the following escape sequences:
:::
::: \\ - Backslash
::: \b - Backspace
::: \f - Formfeed
::: \n - Newline
::: \r - Carriage Return
::: \t - Horizontal Tab
::: \v - Vertical Tab
::: \xnn - Ascii (Latin 1) character expressed as 2 hex digits
::: \unnnn - Unicode character expressed as 4 hex digits
:::
::: Escape sequences are supported even when the L option is used.
:::
::: S - The source is read from an environment variable instead of
::: from stdin. The name of the source environment variable is
::: specified in the next argument after the option string.
