Someone

Note  that  the order of redirections is significant.  For example, the
       command
              
              ls > dirlist 2>&1

       directs both standard output and standard error to  the  file  dirlist,
       while the command
              
              ls 2>&1 > dirlist

       directs  only the standard output to file dirlist, because the standard
       error was duplicated as standard output before the standard output  was
       redirected to dirlist.
