Как показано выше, findstr
добавляет поддержку регулярных выражений, так что это больше похоже grep
.
В чем разница между командами find и findstr в Windows?
В операционной системе Windows, каковы различия между find
и findstr
командами?
Кажется, что оба ищут текст в файлах:
находить
C:\> find /? Searches for a text string in a file or files. FIND [/V] [/C] [/N] [/I] [/OFF[LINE]] "string" [[drive:][path]filename[ ...]] /V Displays all lines NOT containing the specified string. /C Displays only the count of lines containing the string. /N Displays line numbers with the displayed lines. /I Ignores the case of characters when searching for the string. /OFF[LINE] Do not skip files with offline attribute set. "string" Specifies the text string to find. [drive:][path]filename Specifies a file or files to search. If a path is not specified, FIND searches the text typed at the prompt or piped from another command.
Findstr
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 occurences 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 For full information on FINDSTR regular expressions refer to the online Command Reference.

Findstr has more search options and supports regular expressions. I found that findstr does not work with wild cards in the file name.
The command below returns all occurences of search string in multiple files with the pattern Quant_2013-10-25_*.log
find /I "nFCT255c9A" D:\Comp1\Logs\Quant_2013-10-25_*.log
The following command returns nothing or simply does not work
findstr nFCT255c9A D:\Comp1\Logs\Quantum_2013-10-25_*.log
The Old New Thing blog touches on these tools in this post.
In summary: tools developed in parallel to suit slightly different needs; they were simply never combined into one single tool.
findstr extends the functionality of find with several useful features. Some of the key additions include
- findstr supports multiple search strings
- findstr can take as input a file containing file names or directories to search
- findstr supports regular expression
Neither function is suitable for large files or large numbers of files.
