blocks|key|988167|text|处理findstr可执行文件的参数的C运行时遵循一组规则。其中一条规则是使用双引号保护单独参数中的空格/特殊字符，但是，一旦命令行被标记并标识了参数，在将单独的参数传递给主代码之前，将移除引号。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|988168|这意味着这个命令|988169|findstr+/vile+"-min.js"|code-block|syntax|javascript|988170|将在可执行文件中作为|988171|argv[0]+=+findstr+

The C runtime that is handling the arguments to the <code>findstr</code> executable follows a set of rules. One of the rules is to use the double quotes to protect spaces/special characters inside separate arguments, but, once the command line is tokenized and arguments are identified, the quotes are removed before passing the separate arguments to the main code.

That means that this command 

<pre class="lang-dos prettyprint-override"><code>findstr /vile "-min.js"
</code></pre>

will be handled inside the executable as 

<pre><code>argv[0] = findstr 
argv[1] = /vile
argv[2] = -min.js
</code></pre>

and, as <code>findstr</code> accepts argument grouping (as in the <code>/vile</code>) but it also allows arguments starting with both <code>/</code> or <code>-</code>, the <code>-m</code>, <code>-i</code>, <code>-n</code>, <code>-s</code> switches (all valid) are accepted, but <code>-.</code> and <code>-j</code> (unknown) are ignored. 

The command line is bad because no search string can be found in the arguments.

The documented (<code>findstr /?</code>) solution is to use the <code>/c:"stringToMatch"</code> syntax

<pre class="lang-dos prettyprint-override"><code>findstr /vile /c:"-min.js"
</code></pre>

Or you can use the escape character, so the <code>-</code> is not handled as an option argument initial character

<pre class="lang-dos prettyprint-override"><code>findstr /vile "\-min.js"
</code></pre>

blocks|key|1998258|text|作为using+escape+characters+or+/c:的另一种选择，我发现findstr还与前导破折号合作，如果您至少包含一个空格作为前缀(不按字面意思搜索时不影响匹配)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1998259|findstr+/vile+"+-min.js"|code-block|syntax|javascript|1998260|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/46238460/3555883^0|2|U|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$G|H]]|$1|I|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

An alternative to <a href="https://stackoverflow.com/a/46238460/3555883">using escape characters or /c:</a>, I've found findstr also cooperates with leading dashes if you include at least 1 space as prefix (doesn't affect the matches when not searching literally). 
<pre><code>findstr /vile &quot; -min.js&quot;
</code></pre>

I'm going through all JS files recursively and minifying them. However I have to leave some JS files intact.

I've had a lot of success using a combination of <code>for</code>, <code>dir</code> and <code>findstr</code>. But when I wanted to ignore already minified files (files ending with "-min.js") the FINDSTR command broke.

This is the command I've used:

<pre><code>for /f %i in ('dir /b /a-d /s "D:\update" ^| findstr /liv "\admin" ^| findstr /ile ".js" ^| findstr /vile "-min.js" ^| findstr /vile ".min.js"') do echo %i
</code></pre>

With the following errors:

<pre><code>FINDSTR: /. ignored
FINDSTR: /j ignored
FINDSTR: Bad command line
FINDSTR: Write error
FINDSTR: Write error
FINDSTR: Write error
FINDSTR: Write error
</code></pre>

The problem is surely with the <code>findstr /vile "-min.js"</code> clause however I don't know why hyphen is causing a problem since I'm using the /l (literal) flag.

FINDSTR fails when the search string includes a minus character

我正在递归地遍历所有JS文件并缩小它们。然而，我必须保留一些JS文件完整。我在使用for、dir和findstr组合时取得了很大的成功。但是当我想忽略已经缩小的文件(以“-min.js”结尾的文件)时，FINDSTR命令就中断了。这是我使用的命令：for /f %i in ('dir /b /a-d /s "D:\up...
