Ray*_*ega 468 windows scripting command-line batch-file text-files
我正在使用Windows命令行环境编写批处理文件脚本,并希望将文件中某些文本(例如"FOO")的每次出现更改为另一个(例如"BAR").最简单的方法是什么？任何内置功能？
Rac*_*hel 284
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 -encoding ASCII myFile.txt"
解释一下:
powershell 启动powershell.exe,它包含在Windows 7中-Command "... " 是powershell.exe的命令行arg,包含要运行的命令(gc myFile.txt)读取内容myFile.txt(gc是Get-Content命令的缩写)-replace 'foo', 'bar'只需运行replace命令替换foo为bar| Out-File myFile.txt 将输出传递给文件 myFile.txtPowershell.exe应该已经成为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-encoding ASCII
Mik*_*all 181
如果您使用的是支持.Net 2.0的Windows版本,我会替换您的shell. PowerShell通过命令行为您提供.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.我正在使用命令的全名,有更短的别名,但这给了你一些谷歌的东西.
(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,用于在大量文件中替换文本.
安装文件位于SourceForge上.
用法示例:
fart.exe -p -r -c -- C:\tools\perl-5.8.9\* @@APP_DIR@@ C:\tools
将预览替换以在此Perl发行版的文件中递归执行.
唯一的问题:FART网站图标不是很有品位,精致或优雅;)

替换 - 使用字符串替换替换子字符串描述:要使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

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
要使用这个修改过的脚本(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在dostips.com上是使用纯批处理文件进行搜索和替换的示例.
它采用的组合FOR,FIND和CALL SET.
包含字符的行"&<>]|^可能会被错误地处理.

注 - 请务必查看本答案末尾的更新,以获取指向优先级JREPL.BAT的链接,该JREPL.BAT取代REPL.BAT
JREPL.BAT 7.0及以上版本通过该/UTF选项本机支持unicode(UTF-16LE),以及任何其他字符集,包括UTF-8,通过ADO !!!!
我编写了一个名为REPL.BAT的小型混合JScript /批处理实用程序,它非常便于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JScript正则表达式搜索和替换,并将结果写入stdout.
这里有一个简单的例子,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,尤其是替换文本从搜索文本中引用捕获的子字符串的能力.
我在实用程序中包含了许多选项,使其功能非常强大.例如,组合M和X选项可以修改二进制文件!在M多行选项允许跨多行搜索.的X扩展取代模式选项提供了逸出,使包含在所述替代文本的任何二进制值的序列.
整个实用程序可以编写为纯JScript,但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:
::: http://www.dostips.com/forum/viewtopic.php?f=3&t=3855

当您在Windows上使用Git时,只需启动git-bash
并使用即可sed.或者,在使用Windows 10时,启动"在Windows上使用Ubuntu进行Bash"(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 -i -e 's/foo/bar/g' filename
-i 选项用于在文件名上进行编辑.-e option表示要运行的命令.
s用于将找到的表达式"foo"替换为"bar",g用于替换任何找到的匹配项.ereOn注意:
如果要仅在Git存储库的版本化文件中替换字符串,则可能需要使用:
git ls-files <eventual subfolders & filters> | xargs sed -i -e 's/foo/bar/g'
这是奇迹.

我使用过perl,这非常有效.
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
for %x in (<filePattern>) do perl -pi.orig -e "s/<textToReplace>/<textToReplaceWith>/g;" %x

我在这里玩了一些现有的答案,更喜欢我改进的解决方案......
type test.txt | powershell -Command "$input | ForEach-Object { $_ -replace \"foo\", \"bar\" }"
或者如果要将输出再次保存到文件中......
type test.txt | powershell -Command "$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\n\r和unicode序列.在这种情况下将替换引用"Foo"和"Bar":
call replacer.bat "e?C:\content.txt" "\u0022Foo\u0022" "\u0022Bar\u0022"
2)直接替换引用Foo和Bar不引用的地方.
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
该replace.bat文件是如下.我没有找到在同一个批处理文件中包含该函数的方法,因为该%%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
看看是否有任何类似于cmd.exe的实用工具,它要求Windows下的sed等效,也应该适用于这个问题.执行摘要:

Power shell 命令就像一个魅力
(

)
search and replaceStack Overflow 成员编写了两个提供函数的批处理文件，dbenham并在 Windows 中aacini使用native built-in jscript。
他们都是robust和very swift with large files比普通批量脚本，也simpler可用于基本替换文本的。他们都有Windows regular expression模式匹配。
sed-like调用此帮助程序批处理文件repl.bat（由 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"
grep-like调用此帮助程序批处理文件findrepl.bat（由 aacini）。
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"
两者都成为强大的系统范围的实用程序when placed in a folder that is on the path，或者可以与批处理文件在同一文件夹中使用，或者从 cmd 提示符使用。
它们都有case-insensitive开关和许多其他功能。
我更喜欢使用sedWin32的 GNU 实用程序，需要注意以下事项
- 单引号
