telnet和nmap的输出结果到Powershell / cmd会话

Question

So I have a serious fundamental gap in my knowledge that I'm sure has an easy answer, but after googling and looking on here, I can't find what I'm looking for:
I use nmap and telnet on an almost daily basis for checking ports and logging into IP codecs and I use them through either the powershell or cmd consoles, but when I tried to script something and run that script with either a .bat or .ps1 suffix, either will give me the classic not recognized... message. But, if you're able to run it in the console, you should be able to script it, right? How can one go about that?

Sample code for telnet (that works in when inputting to either console, but not in script form):

telnet 192.168.87.21

Sample code for nmap (again, works when inputting to either console, but not in script form):

nmap -p 9999 192.168.87.101

Answer 1

Add a '&' symbol before 'telnet' like that: & telnet 127.0.0.1
