Findstr.exe no está funcionando

Question

Mi sistema ha Findstr.exe pero cuando intento ejecutarlo, me da el siguiente error

FINDSTR: Bad command line 

intentado muchas cosas pero incapaz de fijar. Necesito usar expresiones regulares en mi secuencia de comandos por lotes.

¿Alguna otra sugerencia?

Answer 1

Necesita al menos darle algunos hilos para buscar. Ese mensaje de error es el que se obtiene si no piensa que usted ha proporcionado una cadena de búsqueda (todo lo demás es opcional):

 
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.

Por ejemplo, esto demuestra cómo se puede utilizar expresiones regulares:

 
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 

Answer 2

Eso es lo que dice findstr cuando lo das sin argumentos de línea de comandos. Intenta

findstr/? 

Answer 3

Por supuesto, que no se especifica ningún comando después FINDSTR comando. Escriba FINDSTR /? para obtener ayuda.

Este

un ejemplo de cómo utilizar FINDSTR comando:

FINDSTR /R /C:"your_regex" filename.txt 

Answer 4

Para cualquier otra persona que está luchando con esto, tratar esta simple sintaxis para un comienzo:

findstr /s /i hello *.* 

(ignorar caso, search Todos subdirectorios en la carpeta actual)
