批处理文件，文件副本，文件B除去CR LF

Question

后，我需要一个批处理文件内容复制文件中的除去CR LF

我发现以下后，文件B，但它是简单地把实际％1的值并将其放入文件中，但不加密。

REM Copy and Remove Line Feeds 
@echo off 
echo %1> %2 

rem <nul set /p ".=%1 > c:/temp/%2.txt 

我需要从文件中删除所有的CR LF类，并把文件B中的结果

有许多可能被下载到使这项任务轻松免费的第三方工具。

我写了一个REPL.BAT混合批处理/ JScript实用程序，它可以执行正则表达式搜索并替换文件。它非常灵活，速度非常快。

这是非常容易做到你想要的这个工具。

type A.txt|repl "\r|\n" "" m >B.txt 

这是REPL.BAT脚本。完整的文档嵌入脚本中：

@if (@X)==(@Y) @end /* Harmless hybrid line that begins a JScript comment 

::************ Documentation *********** 
::: 
:::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.

批处理文件，下面你在最快的方式想要的东西：

@echo off 
setlocal DisableDelayedExpansion 
(for /F "usebackq delims=" %%a in (%1) do (
    set /P "=%%a" < NUL 
)) > %2 

你必须把文件A和B中的参数：test.bat的一.txt B.txt
