我有一个文件，其变量在第7行声明为 VERSION = 6.0.196.0。我需要将此行编辑为VERSION = 6.0.200.0
第15行为MANIFEST_BUILD =＆gt; 196。这应该更改为MANIFEST_BUILD =＆gt; 200。 怎么做？
答案 0 :(得分：2)
本回答中的所有解决方案仅使用Windows XP及更高版本的本机命令。
1）这是迄今为止最快的原生批处理解决方案，但它具有最多的限制
<carriageReturn><lineFeed>（Windows样式）终止，而不是<lineFeed>（unix样式）。 XP和Windows 7还有一个额外限制：文件的最后一行必须以<lineFeed>结尾。如果由于FINDSTR中的错误导致最后一行未以<linefeed>结束，则脚本将无限期挂起。有关详细信息，请参阅What are the undocumented features and limitations of the Windows FINDSTR command?。
@echo off
setlocal enableDelayedExpansion
set "file=test.txt"
REM redirect input from your file and output to a new file
<"%file%" >"%file%.new" (
REM preserve lines 1-6
for /l %%N in (1 1 6) do (
set "ln="
set /p "ln="
echo(!ln!
)
REM replace the next line (7)
set /p "ln="
echo VERSION=6.0.196.0
REM preserve lines 8-14
for /l %%N in (8 1 14) do (
set "ln="
set /p "ln="
echo(!ln!
)
REM replace the next line (15)
set /p "ln="
REM The > below must be escaped
echo MANIFEST_BUILD =^>200
REM preserve the remaining lines
findstr "^"
)
REM replace your original file with the new file
>nul move /y "%file%.new" "%file%"
2）下一个选项要慢得多，但限制要少得多。
: 此外，无论原始文件使用何种类型的终结符，输出中的所有行都将由<carriageReturn><lineFeed>终止。
@echo off
setlocal disableDelayedExpansion
set "file=test.txt"
>"%file%.new" (
for /f "tokens=1* delims=:" %%A in ('findstr /n "^" "%file%"') do (
if %%A==7 (
echo VERSION=6.0.196.0
) else if %%A==15 (
echo MANIFEST_BUILD =^>200
) else echo(%%B
)
)
move /y "%file%.new" "%file%"
3）此选项与选项2几乎相同，只是它允许行以:开头。它甚至比选项2）慢。
@echo off
setlocal disableDelayedExpansion
set "file=test.txt"
>"%file%.new" (
for /f "delims=" %%A in ('findstr /n "^" "%file%"') do (
for /f "delims=:" %%B in ("%%A") do (
if %%B==7 (
echo VERSION=6.0.196.0
) else if %%B==15 (
echo MANIFEST_BUILD =^>200
) else (
set "ln=%%A"
setlocal enableDelayedExpansion
echo(!ln:*:=!
endlocal
)
)
)
)
move /y "%file%.new" "%file%"
4）最后一个选项是迄今为止最强大的选项。它使用我编写的混合JScript / Batch实用程序脚本，可用于处理文本文件。该脚本仍然只使用所有现代Windows平台（XP以后）本机的命令。
此选项比选项1慢，但它可以在合理的时间内处理非常大的文件。它比选项2和3快得多，对于大文件来说速度太慢了。
此选项还会保留原始文件中存在的行终止符。
我不知道这个选项的任何限制。
这是依赖于我的REPL.BAT实用程序
的脚本@echo off
set "file=test.txt"
findstr /n "^" "%file%" | repl "^(7:.*)" "VERSION=6.0.196.0" m | repl "^(15:.*)" "MANIFEST_BUILD =>200" m | repl "^\d*:" "" m>"%file%.new"
>nul move /y "%file%.new" "%file%"
这是上面脚本所需的REPL.BAT实用程序。 REPL.BAT应该放在你的PATH中。完整的文档嵌入在脚本中。

::************ 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.
