| 103.Sh BUGS 104.Nm Nice 105is particular to 106.Xr sh 1 . 107If you use 108.Xr csh 1 , 109then commands executed with ``&'' are automatically immune to hangup 110signals while in the background. 111.Pp 112.Nm Nice 113is built into 114.Xr csh 1 115with a slightly different syntax than described here. The form 116.Ql nice +10 117nices to positive nice, and 118.Ql nice \-10 119can be used 120by the super-user to give a process more of the processor. | |
