[Message part 1 (text/plain, inline)]

Hi,


Running "grep (GNU grep) 3.0" as part of Git for Windows (Git-2.16.2-64-bit.exe)

in bash shell.


It seems like grep isn't matching with a caret (start-of-line) on the first line of a file.


> head <file>

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnitySpeechToText.Utilities;

namespace UnitySpeechToText.Services
{
    /// <summary>
    /// Base class for streaming speech-to-text SDK.
    /// </summary>



> grep "^using" <file>

using System.Collections.Generic;
using UnityEngine;
using UnitySpeechToText.Utilities;

> grep "using" <file>
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnitySpeechToText.Utilities;


Thanks,

I don't observe the problem in upstream grep, so quite possibly this is a 
packaging issue in Git for Windows. I suggest reporting the bug there.

Thanks, and by the above, I'm closing this and marking it as "notabug"

Most likely you have a BOM (Byte Order Mark) on the first line.

(It would be cool, though, if grep could ignore that mark.)
