我已经知道了这个问题的显而易见的答案: "只需下载<插入您最喜欢的Windows grep或类似grep工具>。" 但是，我在一个受本地IT人员严格控制的环境中工作，他们控制着我们允许在计算机上安装什么。可以说：我有在Windows XP上访问Perl的权限。下面是一个我想出来的快速Perl脚本，它可以实现我想要的功能，但我还没有想出如何设置批处理文件，以便我可以将命令输出或传递文件（或文件列表？）作为“表达式”的参数之后：
perl -n -e "print $_ if (m![expression]!);" [filename]
我该如何编写批处理脚本，以便我可以做一些类似下面的事情：
dir | grep.bat mypattern grep.bat mypattern myfile.txt
编辑：尽管我标记了另一个“答案”，但我想向Ray Hayes answer致敬，因为它确实是“Windows Way”来做到这一点，即使另一个答案在技术上更接近我想要的。
大部分grep的功能已经在Windows应用程序FindStr.exe中提供，该程序是Windows 2000、XP和Vista机器的一部分！ 它提供RegExpr等功能。
比批处理文件调用Perl要简单得多！
c:\>FindStr /?
Searches for strings in files.
FINDSTR [/B] [/E] [/L] [/R] [/S] [/I] [/X] [/V] [/N] [/M] [/O] [/P] [/F:file]
[/C:string] [/G:file] [/D:dir list] [/A:color attributes] [/OFF[LINE]]
strings [[drive:][path]filename[ ...]]
/B Matches pattern if at the beginning of a line.
/E Matches pattern if at the end of a line.
/L Uses search strings literally.
/R Uses search strings as regular expressions.
/S Searches for matching files in the current directory and all
subdirectories.
/I Specifies that the search is not to be case-sensitive.
/X Prints lines that match exactly.
/V Prints only lines that do not contain a match.
/N Prints the line number before each line that matches.
/M Prints only the filename if a file contains a match.
/O Prints character offset before each matching line.
/P Skip files with non-printable characters.
/OFF[LINE] Do not skip files with offline attribute set.
/A:attr Specifies color attribute with two hex digits. See "color /?"
/F:file Reads file list from the specified file(/ stands for console).
/C:string Uses specified string as a literal search string.
/G:file Gets search strings from the specified file(/ stands for console).
/D:dir Search a semicolon delimited list of directories
strings Text to be searched for.
[drive:][path]filename
Specifies a file or files to search.
Use spaces to separate multiple search strings unless the argument is prefixed
with /C. For example, 'FINDSTR "hello there" x.y' searches for "hello" or
"there" in file x.y. 'FINDSTR /C:"hello there" x.y' searches for
"hello there" in file x.y.
Regular expression quick reference:
. Wildcard: any character
* Repeat: zero or more occurances of previous character or class
^ Line position: beginning of line
$ Line position: end of line
[class] Character class: any one character in set
[^class] Inverse class: any one character not in set
[x-y] Range: any characters within the specified range
\x Escape: literal use of metacharacter x
\<xyz Word position: beginning of word
xyz\> Word position: end of word
下载并安装ack。它是grep的优秀替代品，由于Perl的魔术双模.BAT / Perl脚本技术支持，它将在命令行上为您工作。
@rem = '--*-Perl-*--
@echo off
perl -x -S %0 %*
goto endofperl
@rem -- BEGIN PERL -- ';
#!d:/Perl/bin/perl.exe -w
#line 10
use strict;
#use Test::Setup;
use Getopt::Long;
Getopt::Long::Configure ("bundling");
my $ignore_case = 0;
my $number_line = 0;
my $invert_results = 0;
my $verbose = 0;
my $result = GetOptions(
'i|ignore_case' => \$ignore_case,
'n|number' => \$number_line,
'v|invert' => \$invert_results,
'verbose' => \$verbose,
);
my $regex = shift;
if ( $ignore_case ) {
$regex = "(?i:$regex)";
}
$regex = qr/$regex/;
print "\$regex=$regex\n";
if ( $verbose ) {
print "Verbose: Ignoring case.\n" if $ignore_case;
print "Verbose: Printing file name and line number.\n" if $number_line;
print "Verbose: Inverting result set.\n" if $invert_results;
print "\n";
}
@ARGV = map { glob "$_" } @ARGV;
while ( <> ) {
my $matches = m/$regex/;
next unless $matches ^ $invert_results;
print "$ARGV\:$.:" if $number_line;
print;
}
__END__
:endofperl
首先，将其转换为真正的脚本而不是一行代码：
use strict;
use warnings;
my $pattern = shift or die "Usage: $0 <pattern> [files|-]\n";
while (<>) { print if /$pattern/ }
pl2bat mygrep.pl
@echo off
perl -x -S script.pl %1
"%1"将把参数传递给Perl脚本。将其保存为.bat文件，然后您就可以开始了。
gcc -MM files | yourbat regexp。我尝试过使用 ack，但得到了意外的结果。 - Gauthier我同意Axeman和Hayes先生关于使用更好的工具来完成工作的观点。话虽如此，你可以尝试在批处理文件中使用以下代码来对文件通配符表达式运行自定义脚本：
@echo off
for /f "usebackq delims==" %%f in (`dir /w /b %2`) do (
perl -n -e "print $_ if (m!%1!);" "%%f"
REM or something like: myperlscript.pl %1 "%%f"
)
这样，您可以执行类似于“grep mypattern myfile.txt”、“grep mypattern .”、“grep mypattern *.doc”等操作。
