λ 经常导致输入的时候出问题，我是把它改为 $。

Cmd

vendor\clink.lua

        local lambda = "λ"

改为：

        local lambda = "$"

PowerShell

vendor\profile.ps1

    Microsoft.PowerShell.Utility\Write-Host "`nλ " -NoNewLine -ForegroundColor "DarkGray"

改为：

    Microsoft.PowerShell.Utility\Write-Host "`n$ " -NoNewLine -ForegroundColor "DarkGray"

Bash

vendor\git-for-windows\etc\profile.d\git-prompt.sh

  PS1="$PS1"'λ '                 # prompt: always λ 

改为：

  PS1="$PS1"'$ '                 # prompt: always $
