我正在使用Windows命令行环境编写一个批处理文件脚本，并希望更改文件中每次出现的一些文本(例如。“FOO”)和另一个(ex。“酒吧”)。最简单的方法是什么?有内置函数吗?
当前回答
可能有点晚了，但我经常在寻找类似的东西，因为我不想经历让软件被批准的痛苦。
但是，您通常以各种形式使用FOR语句。有人创建了一个有用的批处理文件来进行搜索和替换。请看这里。重要的是要理解所提供的批处理文件的局限性。由于这个原因，我没有复制这个答案中的源代码。
其他回答
我不认为有任何内置命令可以做到这一点。我建议你下载Gnuwin32或UnxUtils，并使用sed命令(或只下载sed):
sed -c s/FOO/BAR/g filename
下载Cygwin(免费)并在Windows命令行中使用类unix命令。
您最好的选择:sed
注意-请确保在这个答案的末尾看到一个链接到高级JREPL.BAT的更新，它取代了REPL.BAT JREPL.BAT 7.0及以上版本通过/UTF选项原生支持unicode (UTF- 16le)，以及通过ADO!!!!支持任何其他字符集，包括UTF-8
我已经编写了一个小型的JScript/批处理混合实用程序REPL.BAT，它非常方便地通过命令行或批处理文件修改ASCII(或扩展ASCII)文件。纯粹的本机脚本不需要安装任何第三方可执行文件，它可以在任何现代Windows版本从XP开始。它也非常快，特别是与纯批处理解决方案相比。
bat只是读取stdin，执行JScript正则表达式搜索和替换，并将结果写入stdout。
下面是一个简单的例子，关于如何在test.txt中用bar替换foo，假设REPL.BAT在你的当前文件夹中，或者更好的是，在你的PATH中的某个地方:
type test.txt|repl "foo" "bar" >test.txt.new
move /y test.txt.new test.txt
JScript的正则表达式功能使其非常强大，特别是替换文本引用从搜索文本捕获的子字符串的能力。
我在实用程序中包含了许多选项，使其非常强大。例如，结合M和X选项可以修改二进制文件!M多行选项允许跨多行搜索。X eXtended替换模式选项提供转义序列，允许在替换文本中包含任何二进制值。
整个实用程序可以写成纯JScript，但是混合批处理文件消除了每次想要使用该实用程序时显式指定CSCRIPT的需要。
下面是REPL.BAT脚本。脚本中嵌入了完整的文档。

::************ Documentation ***********
::REPL.BAT version 6.2
:::
:::REPL Search Replace [Options [SourceVar]]
:::REPL /?[REGEX|REPLACE]
:::REPL /V
:::
::: Performs a global regular expression 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. If a single argument of /?REGEX, then opens up Microsoft's
::: JScript regular expression documentation within your browser. If a single
::: argument of /?REPLACE, then opens up Microsoft's JScript REPLACE
::: documentation within your browser.
:::
::: If called with a single argument of /V, case insensitive, then prints
::: the version of REPL.BAT.
:::
::: 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.
:::
::: For example, $& represents the portion of the source that matched
::: the entire search pattern, $1 represents the first captured
::: submatch, $2 the second captured submatch, etc. A $ literal
::: can be escaped as $$.
:::
::: An empty replacement string must be represented as "".
:::
::: Replace substitution pattern syntax is fully 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.
:::
::: A - Only print altered lines. Unaltered lines are discarded.
::: If the S options is present, then prints the result only if
::: there was a change anywhere in the string. The A option is
::: incompatible with the M option unless the S option is present.
:::
::: 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.
:::
::: I - Makes the search case-insensitive.
:::
::: J - The Replace argument represents a JScript expression.
::: The expression may access an array like arguments object
::: named $. However, $ is not a true array object.
:::
::: The $.length property contains the total number of arguments
::: available. The $.length value is equal to n+3, where n is the
::: number of capturing left parentheses within the Search string.
:::
::: $[0] is the substring that matched the Search,
::: $[1] through $[n] are the captured submatch strings,
::: $[n+1] is the offset where the match occurred, and
::: $[n+2] is the original source string.
:::
::: Arguments $[0] through $[10] may be abbreviated as
::: $1 through $10. Argument $[11] and above must use the square
::: bracket notation.
:::
::: L - The Search is treated as a string literal instead of a
::: regular expression. Also, all $ found in the Replace string
::: are treated as $ literals.
:::
::: M - Multi-line mode. The entire contents of stdin is read and
::: processed in one pass instead of line by line, thus enabling
::: search for \n. This also enables preservation of the original
::: line terminators. If the M option is not present, then every
::: printed line is terminated with carriage return and line feed.
::: The M option is incompatible with the A option unless the S
::: option is also present.
:::
::: Note: If working with binary data containing NULL bytes,
::: then the M option must be 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. Without
::: the M option, ^ anchors the beginning of the string, and $ the
::: end of the string. With the M option, ^ anchors the beginning
::: of a line, and $ the end of a line.
:::
::: V - Search and Replace represent the name of environment
::: variables that contain the respective values. An undefined
::: variable is treated as an empty string.
:::
::: X - Enables extended substitution pattern syntax with support
::: for the following escape sequences within the Replace string:
:::
::: \\ - Backslash
::: \b - Backspace
::: \f - Formfeed
::: \n - Newline
::: \q - Quote
::: \r - Carriage Return
::: \t - Horizontal Tab
::: \v - Vertical Tab
::: \xnn - Extended ASCII byte code expressed as 2 hex digits
::: \unnnn - Unicode character expressed as 4 hex digits
:::
::: Also enables the \q escape sequence for the Search string.
::: The other escape sequences are already standard for a regular
::: expression Search string.
:::
::: Also modifies the behavior of \xnn in the Search string to work
::: properly with extended ASCII byte codes.
:::
::: Extended escape sequences are supported even when the L option
::: is used. Both Search and Replace support all of the extended
::: escape sequences if both the X and L opions are combined.
:::
::: Return Codes: 0 = At least one change was made
::: or the /? or /V option was used
:::
::: 1 = No change was made
:::
::: 2 = Invalid call syntax or incompatible options
:::
::: 3 = JScript runtime error, typically due to invalid regex
:::
::: REPL.BAT was written by Dave Benham, with assistance from DosTips user Aacini
::: to get \xnn to work properly with extended ASCII byte codes. Also assistance
::: from DosTips user penpen diagnosing issues reading NULL bytes, along with a
::: workaround. REPL.BAT was originally posted at:
::: http://www.dostips.com/forum/viewtopic.php?f=3&t=3855

重要更新
我已经停止了REPL.BAT的开发，并将其替换为JREPL.BAT。这个更新的实用程序具有与REPL.BAT相同的功能，还有更多:
通过原生CSCRIPT Unicode功能支持Unicode UTF-16LE，以及通过ADO支持任何其他字符集(包括UTF-8)。 直接从文件读取/直接写入文件:不需要管道、重定向或移动命令。 合并用户提供的JScript 翻译工具类似于unix tr，只是它也支持regex搜索和JScript替换 丢弃不匹配的文本 带有行号的前缀输出行 和更多的……
与往常一样，完整的文档嵌入到脚本中。
原来的简单解现在更简单了:
jrepl "foo" "bar" /f test.txt /o -
JREPL.BAT的当前版本可从DosTips获得。阅读该线程中的所有后续帖子，以查看使用示例和开发历史。
dostips.com上的BatchSubstitute.bat是一个使用纯批处理文件进行搜索和替换的示例。
它使用FOR、FIND和CALL SET的组合。
包含“&<>]|^”字符的行可能会被错误处理。
下面是我在Win XP上发现的一个解决方案。在我运行的批处理文件中，我包括以下内容:
set value=new_value
:: Setup initial configuration
:: I use && as the delimiter in the file because it should not exist, thereby giving me the whole line
::
echo --> Setting configuration and properties.
for /f "tokens=* delims=&&" %%a in (config\config.txt) do (
call replace.bat "%%a" _KEY_ %value% config\temp.txt
)
del config\config.txt
rename config\temp.txt config.txt
替换后的。bat文件如下所示。我没有找到在同一个批处理文件中包含该函数的方法，因为%%a变量似乎总是给出for循环中的最后一个值。
replace.bat:
@echo off
:: This ensures the parameters are resolved prior to the internal variable
::
SetLocal EnableDelayedExpansion
:: Replaces Key Variables
::
:: Parameters:
:: %1 = Line to search for replacement
:: %2 = Key to replace
:: %3 = Value to replace key with
:: %4 = File in which to write the replacement
::
:: Read in line without the surrounding double quotes (use ~)
::
set line=%~1
:: Write line to specified file, replacing key (%2) with value (%3)
::
echo !line:%2=%3! >> %4
:: Restore delayed expansion
::
EndLocal
