Underneath is a macro that opens a ''TBrowser'' and defines some useful functions. It can be run using ''root myMacro.C'' or with a predefined function
<code>
function TBrowse { root -l "$@" ~/macros/myMacro.C; }
</code>
Run the function in the command line with ''TBrowse analysis.root''. To open all root files in the current directory: ''TBrowse *.root'', even quicker: ''TBrowse *t''.

<code - myMacro.C>
TBrowser a;

void myMacro(){
    std::cout << "Hello World!" << std::endl;
}

void norm(TH1* hist){
    hist->Scale(1./hist->Integral());
    hist->Draw();
}

void range(TH1* hist, double xmin, double xmax){
    hist->GetXaxis()->SetRangeUser(xmin,xmax);
    hist->Draw();
}

double meanRange(TH1* hist, double xmin, double xmax){
    hist->GetXaxis()->SetRangeUser(xmin,xmax);
    return hist->GetMean(1);
}

double integrate(TH1* hist, double xmin, double xmax){
    hist->GetXaxis()->SetRangeUser(xmin,xmax);
    return hist->Integral();
}
