Ls command not working on command line

bhaiyya i just downloaded git and github
On command line i first typed mkdir githubonline
Then i typed ls
it is giving error as ls is unrecognised command
is the ls command different on my system. If so how do I know the correct command for my system

hey @surbhi11 ,
ls is linux command hence you can’t use it on windows.
On windows you can use dir , to do your task,

I hope this helps.
