    Hi, I'm a new using mac and think to have done a big mess.
    I was trying to install gnuplot and I would like to run it directly from the shell, like in a unix system.
    I read in some forums that I had to modify the path...actually i don't really know what I'm talking about, I just thought I had to tell the shell where to go and search gnu plot, nothing more.
    Anyway I wrote on the shell

    echo export PATH=".:$/Applications/" > .profile

    modifying the hidden file .profile.

    The problem I have now is
    1) I can't use anymore the the basic command in the shell, such as cat, top, rm for example.
    2) obvioulsy I didn't solve the problem with gnuplot and I still have to run it in a separate shell.

    Can you help me please to fix these problems?
    thank you.
