Dear @Ratilal_Meher ,
Thanks for writing on the forum. I suggest you take a look at our manual, specifically here, which explains that you have to open the ROOT prompt from the command line, not use the root
command when you are already inside the prompt.
Cheers,
Vincenzo
$ root -l B4.root
root[0] _file0->ls()
or:
$ root
root[0] auto f = new TFile("B4.root")
root[1] f->ls()
or (if you only want to see the contain of the file):
$ rootls B4.root
