Issue running Newman commands in command line

I am receiving following details when running any newman commands like
newman -v
newman run

Details received after running above commands are:

Usage: newman [options] [command]

Options:
-v, --version output the version number
-h, --help display help for command

Commands:
run [options] Initiate a Postman Collection run from a given URL or path

To get available options for a command:
newman -h

Hi @shilpa-cork

have installed the newman globally?
it has to come like below when you check the newman version
install the node.js and install newman again (latest version of both)
