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
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.
