nice
Run a command with modified scheduling priority, print or modify the scheduling priority of a job.
SYNTAX
      nice [Option]... [Command [Arg]...]
OPTION
      -n MyADJUSTMENT
      -MyADJUSTMENT
      --adjustment=MyADJUSTMENT
 Priority can be adjusted by `nice' over the range
  of -20 (the highest priority) 
  to 19 (the lowest)
If no arguments are given, `nice' prints the current scheduling priority, which it inherited.
Otherwise, `nice' runs the given Command with its scheduling 
  priority adjusted. 
  
  If no option for MyADJUSTMENT is given, the priority of the command is 
  incremented by 10. You must have appropriate privileges to specify a negative 
  adjustment. 
  
  Because most shells have a built-in command by the same name, using the unadorned 
  command name in a script or interactively may get you different functionality 
  than that described here.
