[英]findstr.exe is not working
我的系统有findstr.exe但是当我尝试执行它时,它会给我以下错误
FINDSTR: Bad command line
尝试了很多东西,但无法修复。 我需要在我的批处理脚本中使用正则表达式。
还有其他建议吗?
你需要至少给它一些字符串来寻找。 如果它不认为您提供了搜索字符串(其他所有内容都是可选的),则会出现该错误消息:
C:\Documents and Settings\Pax> 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 \ Word position: end of word For full information on FINDSTR regular expressions refer to the online Command Reference.
例如,这显示了如何使用正则表达式:
C:\Documents and Settings\Pax> type qq.cmd @setlocal enableextensions enabledelayedexpansion @echo off set startdir=%cd% set temp=%startdir% set folder= :loop if not "x%temp:~-1%"=="x/" ( set folder=!temp:~-1!!folder! set temp=!temp:~1,-1! goto :loop ) echo.startdir = %startdir% echo.folder = %folder% endlocal
C:\Documents and Settings\Pax> findstr d.r% qq.cmd set temp=%startdir% echo.startdir = %startdir% echo.folder = %folder%
C:\Documents and Settings\Pax> findstr FINDSTR: Bad command line
对于其他正在努力解决此问题的人,请尝试使用以下简单语法:
findstr /s /i hello *.*
(忽略大小写,搜索当前文件夹中的所有子目录)
当你给它没有命令行参数时,这就是findstr所说的。 尝试
findstr/?
当然,在FINDSTR
命令之后没有指定任何命令。 FINDSTR /?
求助。
这个例子如何使用FINDSTR
命令:
FINDSTR /R /C:"your_regex" filename.txt
