Grep equivalent for Windows 7?

Question

Is there a command prompt grep equivalent for Windows 7? That is, I want to filter out the results of a command:

Bash use:

ls | grep root

What would it be from a Windows command prompt?

Answer 1

Findstr sounds like what you want. I use it all the time as an approximate grep-equivalent on the Windows platform.

Another example with pipes:

C:\> dir /B | findstr /R /C:"[mp]"

Answer 2

There are several possibilities:

• Use a port of a Unix grep command. There are several choices. Oft-mentioned are GNUWin32, cygwin, and unxutils. Less well known, but in some ways better, are the tools in the SFUA utility toolkit, which run in the Subsystem for UNIX-based Applications that comes right there in the box with Windows 7 Ultimate edition and Windows Server 2008 R2. (For Windows XP, one can download and install Services for UNIX version 3.5.) This toolkit has a large number of command-line TUI tools, from mv and du, through the Korn and C shells, to perl and awk. It comes in both x86-64 and IA64 flavours as well as x86-32. The programs run in Windows' native proper POSIX environment, rather than with emulator DLLs (such as cygwin1.dll) layering things over Win32. And yes, the toolkit has grep, as well as some 300 others.
• Use one of the many native Win32 grep commands that people have written and published. Tim Charron has a native Win32 version of a modified GNU grep, for example. There are also PowerGREP, Bare Grep, grepWin, AstroGrep, and dnGrep, although these are all GUI programs not TUI programs.
• Use the supplied find and findstr. The syntax is different to that of grep, note, as is the regular expression capability.

If PowerShell commands are allowed, use

PS C:\> Get-ChildItem | Select-String root

or short

PS C:\> ls | sls root

Be aware that the alias sls is only defined beginning with PowerShell version 3.0. You may add an alias for less typing:

PS C:\> New-Alias sls Select-String

To run the PowerShell command directly from cmd, use

C:\>powershell -command "ls | select-string root"

Answer 4

In your early revision you wrote MS-DOS, there's only FIND, as far as I know. But it's an ancient OS not used anymore.

In the Windows NT command prompt(e.g. Win2K and win XP and later, so e.g. win7,win10), you can use find and findstr and if you download GnuWin32 then grep

The basic differences are that findstr has some regular expressions support. Grep supports regular expressions best.

C:\>dir | find "abc"
C:\>dir | find /i "abc"

find /? and findstr /?shows you what the switches do.

Gnuwin32 has "packages". If you download GnuWin32, I suggest the coreutils package for a bunch of basic useful utilities you'd be familiar with, but grep isn't in that one it's its own package.

Added

GnuWin32's grep, last time I checked, is old. Cygwin's grep is far more up to date. Also bear in mind that many people use Virtual Machines rather than windows ports of *nix commands.

Answer 5

If you would rather use grep, rather than findstr, there is a single .exe file version in UnxUtils, so it's portable and there is no need to install it, or use something like Cygwin.

Answer 6

You can try installing Chocolatey on Windows, and through that, install the Gow tool. This will provide you with grep on Windows.

Gow stand for GNU on Windows. It provides Unix command line utilities on Windows.

Answer 7

Bash use

$ ls | grep root

Cmd use

> dir /b | findstr root

where /b stands for bare list of directories and files

Answer 8

I wrote a Windows alternative to grep using Hybrid Batch/JScript code. I wrote this because getting the escape characters right in the GNU Win32 grep port was a real pain. This version works much more like how you would want the GNU version to work in Windows:

@set @junk=1 /*
@cscript //nologo //E:jscript %~f0 %*
@goto :eof */

var args=WScript.Arguments, argCnt=args.Length, stdin=WScript.StdIn, stdout=WScript.StdOut;
var replaceSingleQuotes=false, printMatchesOnly=false, matchString, flagString, regex, argDx=0;

if(argCnt==0) {
    throw new Error("You must provide search criteria.");
}

flagString=""
if(argCnt>1) {
    for(var bLoop=true; bLoop&&argDx<argCnt-1; argDx++) {
        switch(args(argDx)) {
        case '-t': replaceSingleQuotes=true; break;
        case '-o': printMatchesOnly=true; break;
        case '-g': flagString+="g"; break;
        case '-i': flagString+="i"; break;
        case '-m': flagString+="m"; break;
        default: bLoop=false; break;
        }
    }
}
if(replaceSingleQuotes) {
    matchString=args(argCnt-1).replace("'", '"');
} else {
    matchString=args(argCnt-1);
}

if(printMatchesOnly) {
    while(!stdin.AtEndOfStream) {
        var sLine=stdin.ReadLine();
        if(flagString.Length) regex=new RegExp(matchString, flagString);
        else regex=new RegExp(matchString);
        var m,matches=[],startDx=0;
        while((m=regex.exec(sLine.substr(startDx))) !== null) {
            stdout.WriteLine(m[0]);
            startDx+=m.lastIndex;
        }
    }
} else {
    if(flagString.Length) regex=new RegExp(matchString, flagString);
    else regex=new RegExp(matchString);
    while(!stdin.AtEndOfStream) {
        var sLine=stdin.ReadLine();
        if(regex.test(sLine)) {
            stdout.WriteLine(sLine);
        }
    }

}

Multi replacer program has been prepared so that many functions can be carried out by using command line parameters. Command line usage is seen below:

MultiReplacer [Multi Replacer File] | [Search files] | [Search folders]
[-Subs] [-NoSubs] [-IncPtr=pattern] [-ExcPtr=patterns] [-DestDir=destination]
[-DMAnyTime]
[-DMWithinanhour] [-DMToday] [-DMYesterday] [-DMThisweek] [-DMThismonth]
[-DMThisYear]
[-CDMAfter=date] [-CDMBefore=date] [-MinFileSize=bytes count]
[-MaxFileSize=bytes count]
[-Search=text] [-Case] [-NoCase] [-Regex] [-NoRegex] [-SubMatchText=text]
[-ReplaceText=text]
[-StartSearch] [-StartReplace] [-AutoClose] [-StopAfterMatchThisFile] [-StopAfterMatchAll]
[-ExtractedWordsFile=filename] [-ExtractedLinesFile=filename] [-

Answer 10

I would suggest using busybox-w32, since it is only about 500 KB in size and actively maintained.

So that in your case, in the command prompt, it is:

busybox ls | busybox grep root

You can use doskey in a command prompt launch by a batch file to make a command, like:

doskey ls="path\to\busybox.exe" ls $*

doskey grep="path\to\busybox.exe" grep $*

Then you can use ls | grep root on the command prompt.

Answer 11

If you want to add the simplest grep to your windows environment, then navigate to c:\windows\system32 and add a little batch script by using this command:

echo findstr %1 > grep.bat

Now you can

dir | grep notepad.exe

which is really a scary mix of shit. So add another batch script for ls as explained in this post

echo dir %1 > %systemroot%\system32\ls.bat

Now things look a bit familiar

ls | grep notepad

HTH

Answer 12

You can still use your familiar grep and other Linux commands by downloading this tool UnxUtils and add it location to your PATH environment variable

Answer 13

echo findstr %1 %2 %3 %4 %5 > %systemroot%\grep.cmd

That's gonna be quick and dirty equivalent.

C:\Windows\system32>dir | grep xwiz
C:\Windows\system32>findstr xwiz
