save result in a file
when I save a result in file by ls - l > fileinfo command and then when I will dispaly the file by cat fileinfo command it should print the same result. But why it shows the recently created file fileinfo? Because fileinfo was not stored into filename when I write the command ls -l > fileinfo.

ls -l is the first command and after this comand fileinfo created and not recorded in ls -l command.
