No Windows, quais são as diferenças entre os comandos finde findstr?
Ambos parecem procurar texto em arquivos:
encontrar
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.

Provavelmente é mais sobre evolução. A localização remonta aos dias do DOS / UNIX e, posteriormente, o FINDSTR foi adicionado ao Windows. Ambos provavelmente evoluíram e se tornaram mais parecidos.

Eu concordo com a linha do tempo do @Cotreau: FIND é antigo e FINDSTR é mais novo. Duvido que o FIND tenha evoluído para se tornar mais como o FINDSTR; pelo contrário, acredito que o FIND foi preservado como o dinossauro aleijado (como era o DOS em geral) para manter a compatibilidade com versões anteriores (por exemplo, com arquivos em lotes que o utilizam), enquanto o FINDSTR foi adicionado para fornecer um conjunto decente de recursos .

Ah, e a propósito, o comando FIND do DOS / Windows não é nada parecido com o

findcomando Unix ; em vez disso, como paradroid sugere abaixo, o FIND é como uma versão diluída de grep(ou talvez fgrep).
você não vê as diferenças na ajuda?
