这里的很多答案帮助我指出了正确的方向,但是没有一个适合我,所以我发布了我的解决方案。

我有Windows 7,内置PowerShell。这是我用来查找/替换文件中所有文本实例的脚本:

powershell -Command "(gc myFile.txt) -replace 'foo', 'bar' | Out-File myFile.txt"

解释一下:

  • powershell启动了PowerShell.exe,它包含在Windows 7中
  • -Command "... "是powershell.exe的命令行arg,其中包含要运行的命令
  • (gc myFile.txt)读取myFile.txt的内容(gcGet-Content命令的缩写)
  • -replace 'foo', 'bar'只需运行替换命令即可将foo替换为bar
  • | Out-File myFile.txt将输出通过管道传输到文件myFile.txt

Powershell.exe应该是您的PATH语句的一部分,但如果没有,您可以添加它。它在我的机器上的位置是C:\WINDOWS\system32\WindowsPowerShell\v1.0

如果您使用的是支持.Net 2.0的Windows版本,我会替换您的shell。 PowerShell从命令行为您提供.Net的全部功能。内置了许多命令行开关。以下示例将解决您的问题。我使用的是命令的全名,有较短的别名,但这可以为你提供一些东西。

(Get-Content test.txt) | ForEach-Object { $_ -replace "foo", "bar" } | Set-Content test2.txt

刚刚使用 FART (“ F ind A nd R eplace T ext“命令行实用程序”:
优秀的小免费软件,可在大量文件中替换文本。

设置文件are on SourceForge

用法示例:

fart.exe -p -r -c -- C:\tools\perl-5.8.9\* @@APP_DIR@@ C:\tools

将预览替换以在Perl发行版的文件中递归执行。

唯一的问题:FART网站图标并不精致,精致或优雅;)

替换 - 使用字符串替换替换子字符串 描述:要用另一个字符串替换子字符串,请使用字符串替换功能。这里显示的示例用字符串变量str中的“the”替换所有出现的“teh”拼写错误。

set str=teh cat in teh hat
echo.%str%
set str=%str:teh=the%
echo.%str%

脚本输出:

teh cat in teh hat
the cat in the hat

参考:http://www.dostips.com/DtTipsStringManipulation.php#Snippets.Replace

答案 4 :(得分:52)

创建文件replace.vbs:

Const ForReading = 1    
Const ForWriting = 2

strFileName = Wscript.Arguments(0)
strOldText = Wscript.Arguments(1)
strNewText = Wscript.Arguments(2)

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(strFileName, ForReading)
strText = objFile.ReadAll
objFile.Close

strNewText = Replace(strText, strOldText, strNewText)
Set objFile = objFSO.OpenTextFile(strFileName, ForWriting)
objFile.Write strNewText  'WriteLine adds extra CR/LF
objFile.Close

要使用此修订脚本(我们称之为replace.vbs),只需在命令提示符下键入与此类似的命令:

cscript replace.vbs "C:\Scripts\Text.txt" "Jim " "James "

BatchSubstitute.bat on dostips.com是使用纯批处理文件进行搜索和替换的示例。

它使用FORFINDCALL SET的组合。

"&<>]|^中包含字符的行可能会被错误处理。

注意 - 请务必在此答案末尾看到更新,以获取取代REPL.BAT的高级JREPL.BAT的链接
JREPL.BAT 7.0 and above通过/UTF选项本地支持unicode(UTF-16LE),以及任何其他字符集,包括UTF-8,通过ADO !!!!


I have written a small hybrid JScript/batch utility called REPL.BAT通过命令行或批处理文件修改ASCII(或扩展ASCII)文件非常方便。纯粹的本机脚本不需要安装任何可执行的第三方,并且它适用于从XP开始的任何现代Windows版本。它也非常快,特别是与纯批量解决方案相比时。

REPL.BAT只读取stdin,执行JScr​​ipt正则表达式搜索和替换,并将结果写入stdout。

这是一个简单的例子,说明如何在test.txt中用bar替换foo,假设REPL.BAT在你当前的文件夹中,或者更好,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正则表达式功能使其功能非常强大,尤其是替换文本能够从搜索文本中引用捕获的子字符串。

我在实用程序中包含了许多选项,使其功能非常强大。例如,组合MX选项可以修改二进制文件! M多行选项允许跨多行搜索。 X扩展替换模式选项提供了转义序列,允许在替换文本中包含任何二进制值。

整个实用程序可以编写为纯JScript,但是混合批处理文件无需在每次要使用该实用程序时显式指定CSCRIPT。

这是REPL.BAT脚本。完整的文档嵌入在脚本中。

::************ 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:

重要更新

我已停止开发REPL.BAT,并将其替换为JREPL.BAT。这个较新的实用程序具有REPL.BAT的所有相同功能,还有更多:

  • Unicode UTF-16LE通过本机CSCRIPT unicode功能支持,以及通过ADO支持任何其他字符集(包括UTF-8)。
  • 直接从/直接读取文件:不需要管道,重定向或移动命令。
  • 合并用户提供的JScript
  • 类似于unix tr的翻译工具,只有它还支持正则表达式搜索和JScript替换
  • 放弃不匹配的文字
  • 前缀带行号
  • 的输出行
  • 以及......

与往常一样,完整的文档嵌入在脚本中。

使用FNR

使用fnr实用程序。它比fart有一些优势:

  • 正则表达式
  • 可选的GUI。有一个“生成命令行按钮”来创建命令行文本以放入批处理文件。
  • 多行模式:GUI允许您轻松使用多行模式。在FART中,您必须手动转义换行符。
  • 允许您选择文本文件编码。还有一个自动检测选项。

在此处下载FNR:http://findandreplace.io/?z=codeplex

用法示例: fnr --cl --dir "<Directory Path>" --fileMask "hibernate.*" --useRegEx --find "find_str_expression" --replace "replace_string"

我认为没有办法使用任何内置命令。我建议您下载Gnuwin32UnxUtils之类的内容并使用sed命令(或仅下载sed):

sed -c s/FOO/BAR/g filename

就个人而言,我喜欢以下解决方案:   - http://www.dostips.com/DtTipsStringManipulation.php#Snippets.Replace

我们还广泛使用Dedupe功能帮助我们每天通过SMTP发送大约500封电子邮件: - https://groups.google.com/forum/#!topic/alt.msdos.batch.nt/sj8IUhMOq6o

这些都是本地工作,不需要额外的工具或实用程序。

代用品:

DEL New.txt
setLocal EnableDelayedExpansion
For /f "tokens=* delims= " %%a in (OLD.txt) do (
Set str=%%a
set str=!str:FOO=BAR!
echo !str!>>New.txt
)
ENDLOCAL

DEDUPLICATOR(注意使用-9表示ABA号码):

REM DE-DUPLICATE THE Mapping.txt FILE
REM THE DE-DUPLICATED FILE IS STORED AS new.txt

set MapFile=Mapping.txt
set ReplaceFile=New.txt

del %ReplaceFile%
::DelDupeText.bat
rem https://groups.google.com/forum/#!topic/alt.msdos.batch.nt/sj8IUhMOq6o
setLocal EnableDelayedExpansion
for /f "tokens=1,2 delims=," %%a in (%MapFile%) do (
set str=%%a
rem Ref: http://www.dostips.com/DtTipsStringManipulation.php#Snippets.RightString
set str=!str:~-9!
set str2=%%a
set str3=%%a,%%b

find /i ^"!str!^" %MapFile%
find /i ^"!str!^" %ReplaceFile%

当您使用Git on Windows时,只需启动 public CustomImageView(Context context, AttributeSet attrs) { super(context, attrs); String android_schemas = "http://schemas.android.com/apk/res/android"; int srcId = attrs.getAttributeResourceValue(android_schemas, "src", -1); } 即可 并使用 git-bash 。或者,在使用Windows 10时,在Windows上启动&#34; Bash on Ubuntu&#34; (来自Linux子系统)并使用 sed

它是一个流编辑器,但可以使用以下命令直接编辑文件:

sed
  • sed -i -e 's/foo/bar/g' filename 选项用于在文件名上进行编辑。
  • -i选项表示要运行的命令。
    • -e用于替换找到的表达式&#34; foo&#34;用&#34; bar&#34; s用于替换找到的所有匹配项。

ereOn注意:

如果您只想替换Git存储库的版本化文件中的字符串,您可能需要使用:

g

可以创造奇迹。

我使用过perl,这非常有用。

perl -pi.orig -e "s/<textToReplace>/<textToReplaceWith>/g;" <fileName>

.orig是它将附加到原始文件的扩展名

对于许多匹配的文件,例如* .html

我在这里讨论了一些现有的答案,并且更喜欢我改进的解决方案......

type test.txt | powershell -Command "$input | ForEach-Object { $_ -replace \"foo\", \"bar\" }"

或者如果要将输出再次保存到文件...

type test.txt | powershell -Command "$input | ForEach-Object { $_ -replace \"foo\", \"bar\" }" > outputFile.txt

这样做的好处是可以管理任何程序的输出。也会考虑使用正则表达式。无法解决如何将其变成BAT文件以便于使用......: - (

使用replacer.bat

1)使用e?选项来评估特殊字符序列,如\n\r和unicode序列。在这种情况下,将替换引用的"Foo""Bar"

call replacer.bat "e?C:\content.txt" "\u0022Foo\u0022" "\u0022Bar\u0022"

2)直接替换未引用FooBar的地方。

call replacer.bat "C:\content.txt" "Foo" "Bar"

这是我在Win XP上找到的解决方案。在我正在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

replace.bat文件如下。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

在Windows下查看要求提供等效的Is there any sed like utility for cmd.exe,也应该适用于此问题。执行摘要:

  • 可以在批处理文件中完成,但它不是很好
  • 如果您可以安装或只是复制exe,可以使用大量可用的第三方可执行文件
  • 如果你需要能够在没有修改等的Windows机器上运行的东西,可以用VBScript或类似的东西来完成。

可能有点晚了,但我经常寻找类似的东西,因为我不想轻易获得软件批准。

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。看看here。了解所提供的批处理文件的局限性非常重要。因此,我不会在此答案中复制源代码。

提供search and replace函数的两个批处理文件由Stack Overflow成员dbenhamaacini在Windows中使用native built-in jscript编写。

与普通批处理脚本相比,它们都是robustvery swift with large files,而simpler用于基本替换文本。它们都有Windows regular expression模式匹配。

  1. sed-like帮助程序批处理文件名为repl.bat(dbenham)。

    使用L文字开关的示例:

    echo This is FOO here|repl "FOO" "BAR" L
    echo and with a file:
    type "file.txt" |repl "FOO" "BAR" L >"newfile.txt"
    
  2. grep-like帮助程序批处理文件名为findrepl.bat(由aacini提供)。

    正则表达式处于活动状态的示例:

    echo This is FOO here|findrepl "FOO" "BAR" 
    echo and with a file:
    type "file.txt" |findrepl "FOO" "BAR" >"newfile.txt"
    
  3. 两者都成为功能强大的系统级实用程序when placed in a folder that is on the path,或者可以在批处理文件的同一文件夹中使用,或者从cmd提示符中使用。

    他们都有case-insensitive个开关以及许多其他功能。

刚遇到类似的问题 - “搜索并替换文件中的文本”,但除了文件名和搜索/重播之外,我需要使用正则表达式。因为我不熟悉Powershell并希望保存我的搜索以供以后使用,所以我需要更“用户友好”的东西(如果它有GUI,则更好)。

所以,谷歌搜索:)我找到了一个很棒的工具 - FAR (Find And Replace)(不是FART)。

这个小程序有很好的GUI和支持正则表达式来搜索文件名和文件。唯一的缺点是,如果你想保存设置,你必须以管理员身份运行程序(至少在Win7上)。

我更喜欢使用GNU utilities for Win32中的sed,需要注意以下几点

  
      
  • 单引号''在Windows中不起作用,请改用""
  •   
  • sed -i 在Windows中无法使用,需要文件交换
  •   

因此sed在Windows文件中查找和替换文本的工作代码如下

sed -e "s/foo/bar/g" test.txt > tmp.txt && mv tmp.txt test.txt
