\n

-s scheduler<\/p>\n<\/td>\n

\n

Specify one of the following scheduler policies:<\/p>\n

    \n
  • SCHED_FIFO<\/li>\n
  • SCHED_RR<\/li>\n
  • SCHED_OTHER<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
\n

-p priority<\/p>\n<\/td>\n

\n

Specify the task priority.<\/p>\n<\/td>\n<\/tr>\n

\n

command [arguments]<\/p>\n<\/td>\n

\n

Specify the command and its optional arguments to run with the specified scheduling.<\/p>\n<\/td>\n<\/tr>\n

-P pid<\/td>\n\n

Specify a currently executing process ID to set the scheduling for.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/dd>\n<\/dl>\n

Example:<\/h3>\n
\n
\n
rtsched\u00a0\u00a0 -s SCHED_FIFO -p 10 a.out<\/div>\n
\u00a0<\/div>\n
The above example executes file a.out with SCHED_FIFO at a priority of 10.<\/p>\n

rtsched\u00a0 -s SCHED_RR -p 10 -P 23131<\/p>\n

The above example executes the task corresponding to pid 23131 with SCHED_RR at a priority of 10.<\/p><\/div>\n<\/dd>\n<\/dl>\n
