47: .Op Ar argument ...
48: .Sh DESCRIPTION
1.5 aaron 49: .Nm
1.1 deraadt 50: runs
51: .Ar utility
52: at an altered scheduling priority.
1.5 aaron 53: If an
54: .Ar increment
1.1 deraadt 55: is given, it is used; otherwise
56: an increment of 10 is assumed.
1.8 ! aaron 57: The superuser can run utilities with priorities higher than normal by using
1.5 aaron 58: a negative
1.1 deraadt 59: .Ar increment .
60: The priority can be adjusted over a
1.5 aaron 61: range of \-20 (the highest) to 20 (the lowest).
1.1 deraadt 62: .Pp
1.6 aaron 63: The options are as follows:
1.1 deraadt 64: .Bl -tag -width indent
65: .It Fl n Ar increment

1.1 deraadt 71: The
1.5 aaron 72: .Nm
1.1 deraadt 73: utility shall exit with one of the following values:

87: .Pp
1.5 aaron 88: Otherwise, the exit status of
89: .Nm
90: shall be that of
1.1 deraadt 91: .Ar utility .
92: .Sh COMPATIBILITY
1.5 aaron 93: The historic
94: .Fl Ns Ar increment
1.1 deraadt 95: option has been deprecated but is still supported in this implementation.

116: The form
1.1 deraadt 117: .Ql nice +10
118: nices to positive nice, and
119: .Ql nice \-10
120: can be used
