So I am having problems opening ROOT in lxplus. If I just call ROOT by typing “root” it says that the command isn’t found even though I am in the right directory and I have ROOT in there. I have tried typing “./root &” since that is how I open ispy in lxplus but that says Permission Denied. I have tried “chmod +x root” but it doesn’t change anything. Do you know what I am doing wrong? I am probably making a simple mistake since I don’t know many linux commands.
