taskpolicy(8)             BSD System Manager's Manual            taskpolicy(8)

NAME
     taskpolicy -- execute a program with an altered I/O or scheduling policy

SYNOPSIS
     taskpolicy [-d policy] [-b] program [arg1 [...]]

DESCRIPTION
     The taskpolicy program uses the setiopolicy_np(3) and setpriority(2) APIs to execute a program with
     altered I/O or scheduling policies. All children of the specified program also inherit these policies.

     taskpolicy accepts the following flags and arguments:

           -d policy  Run the program after calling setiopolicy_np(3) with an iotype of IOPOL_TYPE_DISK, a
                      scope of IOPOL_SCOPE_PROCESS, and the specified policy. The argument can either be an
                      integer, or a symbolic string like "default" or "throttle", which is interpreted case-insensitively. caseinsensitively.
                      insensitively.

           -g policy  Run the program after calling setiopolicy_np(3) with an iotype of IOPOL_TYPE_DISK, a
                      scope of IOPOL_SCOPE_DARWIN_BG, and the specified policy. The argument is interpreted
                      in the same manor as -d.

           -b         Run the program after calling setpriority(2) with a priority of PRIO_DARWIN_BG.
