所以我用Notepad ++做了这个，但它需要永远。我在文件夹中有几千个文件，需要在每个文件的每一行之前和之后添加一些文本。
这甚至可以在命令行中使用吗？
例如，这是一行：
This is my line.
我希望结果如下：
<text before>This is my line.<text after>
任何帮助将不胜感激！

未经测试但应该这样做：
perl -pi -e 's/(.*)/<text before>$1<text after>/' *
答案 1 :(得分：0)
以下纯本机批处理脚本可以使用，但速度相对较慢。
@echo off
setlocal disableDelayedExpansion
set "prefix=<text before>"
set "suffix=<text after>"
pushd "yourFolder"
for %%F in (*) do (
>"%%F.new" (
for /f "delims=" %%A in ('findstr /n "^" "%%F"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
echo !prefix!!ln:*:=!!suffix!
endlocal
)
)
move /y "%%F.new" "%%F" >nul
)
我编写了一个混合JScript / Batch脚本，可用于高效处理文本文件。使用我的REPL.BAT实用程序，脚本可以像下面这样简单：
@echo off
pushd "yourFolder"
for %%F in (*) do (
type "%%F" | repl "^(.*)" "<text before>$1<text after>" >"%%F.new"
move /y "%%F.new" "%%F" >nul
)
popd
REPL.BAT脚本应位于PATH中的某个位置。
这是REPL.BAT脚本。它与XP以后的所有现代Windows版本兼容。考虑到代码很少，该实用程序功能强大且易于使用。几乎一半的脚本包含嵌入式文档。可以通过在命令提示符下键入REPL /?来查看文档。

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