What's the difference between the find and findstr commands in Windows?
Solution 1
As shown above, findstr
adds regular expressions support, so it's more like grep
.
Solution 2
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
Solution 3
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.
Solution 4
Besides those mentioned:
Solution 5
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.

In Windows, what are the differences between the
find
andfindstr
commands?Both seem to search for text in files:
find
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.

Admin almost 13 yearsIt is probably more about evolution. Find goes back to the DOS/UNIX days, and later FINDSTR was added in Windows. Both have probably evolved, and become more alike.

Admin over 10 yearsI agree with @KCotreau’s timeline: FIND is ancient and FINDSTR is newer. I doubt that FIND has evolved to become more like FINDSTR; rather, I believe FIND was preserved as the crippled dinosaur that it was (as DOS was, in general) in order to maintain backward compatibility (e.g., with batch files that use it), while FINDSTR was added to provide a decent set of features.

Admin over 10 yearsOh, and by the way, the DOS/Windows FIND command is nothing like the Unix
find
command; rather, as paradroid suggests below, FIND is like a watered-down version ofgrep
(or perhapsfgrep
). -
Admin over 8 yearsdon't you see the differences in the help?

crosenblum about 11 yearsBut it's not alway's clear the exact usage and difference if you haven't used both of those frequently. So their perceptions may be different because you may have had far different experiences then they do. Part of a huge problem in learning and career's I call the Experience Gap. Long story.

find
also has some limitations. For example, you couldn't use it to append line numbers to each line becausefind/n""
would not match anything. For that you'll have to usefindstr
