使用通配符掩码替换文件内容

标签: windows batch-file

我搜索了SO,但无法找到类似的主题,所以我决定写一个。我想在我的Windows批处理文件.bat中有一个命令,它可以用通配符掩码替换1个或多个文件的内容。例如:

replace *.txt "searchin? str?ng*" "replacing string"

有人可以告诉我这是否可能?

非常感谢,

Windows没有可以执行此操作的本机命令行工具(可能是PowerShell除外)。但是像sed这样的unix实用程序的Windows端口可以很好地完成工作。任何支持正则表达式搜索和替换的实用程序都可以正常工作,但通配符的语法不是您的示例中的语法。正则表达式非常强大,您将需要阅读一些有关如何使用它们的教程。网上有很多教程。

我写了一个hybrid JScript/batch utility called REPL.BAT,它在stdin上执行正则表达式搜索/替换,并将结果写入stdout。该实用程序是纯脚本,可​​以从XP开始在任何现代Windows机器上本机运行。完整的文档嵌入在脚本中。

使用REPL.BAT,您的示例可以实现为:

@echo off
for %%F in (*.txt) do (
  type "%%F" | repl "searchin. str.ng.*" "replacing string" >"%%F.new"
  move /Y "%%F.new" "%%F"
)

请注意,问题中的?(任意1个字符)在正则表达式中表示为.,而*(任意0个或多个字符)表示为{{1 }}

上述内容很容易转换成通用的REPLACE.BAT“命令”。

.*

然后使用以下方法调用上述内容:

@echo off
for %%F in (%1) do (
  type "%%F" | repl %2 %3 >"%%F.new"
  move /Y "%%F.new" "%%F"
)

这假设REPL.BAT和REPLACE.BAT都在当前目录中,或者在PATH中的某个位置。

这是一个vbs程序。

这些是规则。

特殊字符和序列用于编写正则表达式的模式。下表描述并给出了可以使用的字符和序列的示例。

字符描述

\ 
 Marks the next character as either a special character or a literal. For example, "n" matches the character "n". "\n" matches a newline character. The sequence "\\" matches "\" and "\(" matches "(".

^ 
 Matches the beginning of input.

$ 
 Matches the end of input.

* 
 Matches the preceding character zero or more times. For example, "zo*" matches either "z" or "zoo".

+ 
 Matches the preceding character one or more times. For example, "zo+" matches "zoo" but not "z".

? 
 Matches the preceding character zero or one time. For example, "a?ve?" matches the "ve" in "never". 

.
 Matches any single character except a newline character. 

(pattern)
 Matches pattern and remembers the match. The matched substring can be retrieved from the resulting Matches collection, using Item [0]...[n]. To match parentheses characters ( ), use "\(" or "\)".

x|y
 Matches either x or y. For example, "z|wood" matches "z" or "wood". "(z|w)oo" matches "zoo" or "wood". 

{n}
 n is a nonnegative integer. Matches exactly n times. For example, "o{2}" does not match the "o" in "Bob," but matches the first two o's in "foooood".

{n,} 
 n is a nonnegative integer. Matches at least n times. For example, "o{2,}" does not match the "o" in "Bob" and matches all the o's in "foooood." "o{1,}" is equivalent to "o+". "o{0,}" is equivalent to "o*".

{ n , m } 
 m and n are nonnegative integers. Matches at least n and at most m times. For example, "o{1,3}" matches the first three o's in "fooooood." "o{0,1}" is equivalent to "o?".

[ xyz ] 
 A character set. Matches any one of the enclosed characters. For example, "[abc]" matches the "a" in "plain". 

[^ xyz ] 
 A negative character set. Matches any character not enclosed. For example, "[^abc]" matches the "p" in "plain". 

[ a-z ] 
 A range of characters. Matches any character in the specified range. For example, "[a-z]" matches any lowercase alphabetic character in the range "a" through "z". 

[^ m-z ] 
 A negative range characters. Matches any character not in the specified range. For example, "[m-z]" matches any character not in the range "m" through "z". 

\b 
 Matches a word boundary, that is, the position between a word and a space. For example, "er\b" matches the "er" in "never" but not the "er" in "verb". 

\B 
 Matches a non-word boundary. "ea*r\B" matches the "ear" in "never early". 

\d 
 Matches a digit character. Equivalent to [0-9]. 

\D 
 Matches a non-digit character. Equivalent to [^0-9]. 

\f 
 Matches a form-feed character. 

\n 
 Matches a newline character. 

\r 
 Matches a carriage return character. 

\s 
 Matches any white space including space, tab, form-feed, etc. Equivalent to "[ \f\n\r\t\v]".

\S 
 Matches any nonwhite space character. Equivalent to "[^ \f\n\r\t\v]". 

\t 
 Matches a tab character. 

\v 
 Matches a vertical tab character. 

\w 
 Matches any word character including underscore. Equivalent to "[A-Za-z0-9_]". 

\W 
 Matches any non-word character. Equivalent to "[^A-Za-z0-9_]". 

\num 
 Matches num, where num is a positive integer. A reference back to remembered matches. For example, "(.)\1" matches two consecutive identical characters. 

\ n 
 Matches n, where n is an octal escape value. Octal escape values must be 1, 2, or 3 digits long. For example, "\11" and "\011" both match a tab character. "\0011" is the equivalent of "\001" & "1". Octal escape values must not exceed 256. If they do, only the first two digits comprise the expression. Allows ASCII codes to be used in regular expressions.

\xn
 Matches n, where n is a hexadecimal escape value. Hexadecimal escape values must be exactly two digits long. For example, "\x41" matches "A". "\x041" is equivalent to "\x04" & "1". Allows ASCII codes to be used in regular expressions.
