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?

    don't confuse ms-dos with the command prompt. + use of find and findstr and even grep, for windows.. is surely easily found with a quick search. there are even tables of equivalent commands in linux and windows. also you bash example is not even specific to bash.. just I suppose, *nix OS. – barlop Jun 22 '11 at 21:32

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]"
  • Yeah that seems to be what i'm looking for. I understand there are probably limitations. I'll give it a try. – chrisjlee Jun 22 '11 at 21:11

    why couldn't they just call it grep! – Victor Grazi Sep 8 '15 at 15:15

    @VictorGrazi They actually did at first, see this article. It was originally named qgrep - but was later renamed. – Zitrax Feb 1 '16 at 14:23

    The big problem with findstr is that the regex pattern may not contain alternatives. – Wolf Jun 16 '16 at 13:15
  • The question is about Windows 7, but what other versions of Windows have findstr by default? Since Windows XP? – Peter Mortensen Jan 9 '17 at 20:29

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.
  • cygwin worked for me nicely on Win 7. I needed grep and GnuWin32 grep did not work for me. – Kozuch Feb 21 '14 at 11:58
  • You write I don't see perl in SUA C:\Windows\SUA>dir perl* /s/b File Not Found and running e.g. c shell of SUA I don't see it in /bin – barlop May 27 '15 at 21:12
  • you also write that SFUA is in some ways better. In what ways? – barlop Apr 24 '16 at 11:17
  • @Kozuch unless you state how it didn't work, then your comment is not useful – barlop Apr 24 '16 at 11:18

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"

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.

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.

  • This is interesting but would require installing that tool. – chrisjlee Jun 22 '11 at 21:11

    @Chris: There is no installation. It's just a .zip file of .exe files. The only small downside is that the versions are slightly old. – paradroid Jun 22 '11 at 21:13

    What's the downside of being old? Can software be old? All fresh bytes. – user unknown Jun 23 '11 at 1:43

    GnuWin32 also provides grep for Windows: gnuwin32.sourceforge.net/packages/grep.htm – LiuYan 刘研 Jun 23 '11 at 1:54
  • 3
    @userunknown well, as an example, the unxutils sed command is older and doesn't support \d e.g. \d22 to specify quote. An older wget might not download a page that a newer one will, and if you ask for support they may ask that you get the latest one as that can solve some issues. A really old grep no doubt won't have the level of regex support that a current one has – barlop Sep 3 '14 at 18:59

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.

    It's a package manager , like an apt-get but for windows. It got its name 'cos the developer based it off of NuGet which is a package manager for visual studio, and that sounds like nugget (as in chicken nugget), so he thought he'd be "funny" or "clever" and call his program Chocolatey NuGet . I heard that on a podcast that interviewed him. Gow can be downloaded independently too – barlop Jul 29 '15 at 0:01

    I am new to Gow, after few days of usage I can testify that I like it a lot - it is better than all the older ports of UNIX utils that I had used before. – Radim Cernej Jan 24 '16 at 20:23
  • @RadimCernej your comment isn't useful unless you state how you think it is better. – barlop Jul 18 '16 at 15:57
  • @barlop: Since I wrote my Jan-2016 comment I gradually and completely switched to Gow. So far no bugs, it has all the utilities that I need/use, path are output in Microsoft format (making it easy to copy/paste to other programs). Gow is non-invasive enough (easy to install and remove) that I strongly recommend that you test-drive it. – Radim Cernej Jul 18 '16 at 19:35

Bash use

$ ls | grep root

Cmd use

> dir /b | findstr root

where /b stands for bare list of directories and files

  • @DavidPostill, don't mind, but accepted answer contain multiple excessive and unexplained keys /B, /R and /C OP didn't ask about, while my answer gives exact equivalent – vladkras May 4 '16 at 12:37
  • The /b is to make the dir output the same as the ls output. If you test it you will see the difference. So it is not the exact equivalent. – DavidPostill May 4 '16 at 12:43

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);
        }
    }

}

You can always find the latest version on my Gist page for this.

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

  • unxutils grep isn't as late as you can get.. unx grep is 2.4.2 but gnuwin32 has a later one 2.5.4 – barlop Jul 29 '15 at 0:05

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.

  • it has an android build too – barlop Jul 18 '16 at 15:59

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

-2
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
