我必须用一些特定的扩展名替换所有文件中的一些内容。
例如：在文件夹toChange中我可能有多个子文件夹，现在我想在所有扩展名为isabcd
isxyz更改为html
这个命令的批处理是什么，我正在使用windows
实际上我需要替换多个项目。我有它们的键值形式，需要在文件夹
中的所有文件中逐个替换它们我的文字会有双引号，我想要替换它 我的文字如下
if (loUserAgent.toLowerCase().indexOf("firefox") > -1
|| (loUserAgent.toLowerCase().indexOf("msie") > -1 && loUserAgent.toLowerCase().indexOf("msie 7") != -1))
我希望它转换为
if (loUserAgent.toLowerCase().indexOf(aaa.FIRE_FOX) > -1
|| (loUserAgent.toLowerCase().indexOf(aaa.MSIE) > -1 && loUserAgent.toLowerCase().indexOf(aaa.IE_7) != -1))
conf.txt文件将具有
之类的输入 AAA.PY_ERROR_OCCURRED_WHILE_GETTING_PAYMENT_LIST_SCREEN_FOR_ORG_TYPE:::"Error occurred while getting payment list screen for org type: "
AAA.PY_AO_PAYMENT_LIST_SIZE:::"aoPaymentListSize"
AAA.PY_AO_PAYMENT_STATUS:::"aoPaymentStatus"
:::右侧的文本是需要替换的文本（带双引号），此文本也可能包含特殊字符，左边的字符串是我想要的文本替换为

上面的批处理程序在与原始名称相同的文件中生成其输出，并添加“.txt”扩展名。如果结果正确，请删除批处理文件末尾的REM命令以删除原始.hmtl文件并重命名创建的文件。我用这些数据测试了程序：

conf.txt文件必须位于批处理文件的同一文件夹中。
程序从输入文件中删除空行。如果您愿意，可以轻松修复此问题。
程序可能有点慢。这可能会在某种程度上得到改善，但需要进行大量修改。
编辑：我修改了此程序的先前版本，以便：
请注意，您可以在自己的文本中使用字符组合作为分隔符，例如:::，但在某些批处理管理中，分隔符必须只是一个字符。这个细节迫使我们选择一个不能出现在conf.txt文件中的特定字符。我的程序需要两个不同的特殊字符作为分隔符。我选择了Ascii字符128（Ç）和129（ü）;如果这些字符可能出现在conf.txt文件中，那么您必须选择另一个并在程序中指定的位置更改它们。抱歉，没有其他方法可以在批处理文件中执行此操作。

我编写了一个名为REPL.BAT的混合JScript /批处理实用程序，它可以帮助解决这个问题。我相信它会比任何纯批量解决方案快得多。另一个不错的功能是这个解决方案可以很容易地适用于正则表达式搜索和替换而不是字符串文字搜索和替换。
假设我的REPL.BAT和你的conf.txt与你的html文件在同一个文件夹中，那么下面的脚本应该可以工作：
@echo off
setlocal disableDelayedExpansion
:: Define LF to contain a newline (0x0A) character
set LF=^
:: The 2 blank lines above are critical - DO NOT REMOVE
:: Read the search and replace strings and store them in an "array"
:: Also, create a variable containing a cascading set of piped commands to
:: carry out each search and replace
:: Normally the search is in the s array, and the replacement in the r array.
:: But if the replacement is an empty string, then the search is in the r array
:: and the s array value is undefined.
set "cnt=0"
set "update="
for /f delims^=^ eol^= %%A in (conf.txt) do (
set "ln=%%A"
set /a cnt+=1
setlocal enableDelayedExpansion
for %%n in ("!LF!") do set "ln=!ln::::=%%~n!"
for %%N in (!cnt!) do (
for /f delims^=^ eol^= %%U in (""!update!"") do (
for /f delims^=^ eol^= %%L in ("!ln!") do (
if "!"=="" endlocal
if not defined r%%N (
set "r%%N=%%L"
) else (
set "s%%N=%%L"
)
)
if "!"=="" endlocal
if defined s%%N (
set "update=%%~U|repl s%%N r%%N vl"
) else if defined r%%N (
set "update=%%~U|repl r%%N "" vl"
)
)
)
)
:: Process each file
for %%F in (*.html) do (
echo processing %%F
type "%%F" %update% >"%%F.new"
move /y "%%F.new" "%%F" >nul
)
echo Done!
该脚本构建了一个搜索和替换字符串的“数组”：s1,s2,...sn和r1,r2,...rn
它还构建了一个类似于
的update命令
|repl s1 r1 vl|repl s2 r2 vl...|repl sn rn vl
每个文件都通过一组执行搜索和替换的管道REPL命令传递，每个REPL命令一个。
上述脚本具有以下限制：
update命令长度必须少于8191个字符，因此一次传递中可执行的搜索和替换操作数量有限制。理论上的限制是大约480次替换，但我不知道Windows如何在一个命令中使用那么多管道。:::。这是conf.txt文件设计所固有的以下是上述脚本所需的REPL.BAT文件。完整文档嵌入在脚本中。上面的脚本使用V选项来读取变量中的搜索和替换字符串，使用L选项强制进行文字搜索而不是正则表达式搜索。

:::
:::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 regex 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.
:::
::: B - The Search must match the beginning of a line.
::: Mostly used with literal searches.
:::
::: E - The Search must match the end of a line.
::: Mostly used with literal searches.
:::
::: V - 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.

启动mintty.exe（您的cygwin终端）并执行以下命令。根据需要修改/cygdrive/c/Users/etc。
find /cygdrive/c/Users/Varun/Documents/etc/toChange -type f -iname '*.html' -print0 | xargs -0 sed -i -r -e "/aaa\.[A-Z1-9_]+\s*=/!s/\Wfirefox\W/aaa.FIRE_FOX/g" -e "/aaa\.[A-Z1-9_]+\s*=/!s/\Wmsie 7\W/aaa.IE_7/g" -e "/aaa\.[A-Z1-9_]+\s*=/!s/\Wmsie\W/aaa.MSIE/g"
这意味着：
/path/to/toChange内，f扩展名.html个iles（不是目录）
sed，这将修改内联内容。var aaa.FIRE_FOX =或类似内容的每行不，
[non alpha-numeric]firefox[non alpha-numeric] aaa.FIRE_FOX ......等等。
之前test.html ：
var aaa.FIRE_FOX="firefox"
var aaa.MSIE="msie"
var aaa.IE_7="msie 7"
if (loUserAgent.toLowerCase().indexOf("firefox") > -1
|| (loUserAgent.toLowerCase().indexOf("msie") > -1 && loUserAgent.toLowerCase().indexOf("msie 7") != -1))
find | xargs sed命令后test.html ：
var aaa.FIRE_FOX="firefox"
var aaa.MSIE="msie"
var aaa.IE_7="msie 7"
if (loUserAgent.toLowerCase().indexOf(aaa.FIRE_FOX) > -1
|| (loUserAgent.toLowerCase().indexOf(aaa.MSIE) > -1 && loUserAgent.toLowerCase().indexOf(aaa.IE_7) != -1))
如果这对你不起作用，也许Endoro建议使用像WinGrep这样的GUI可能会更好
