The basic matching 462expressions are the same as those used in 463.Xr iostat 8 464with one difference. Instead of specifying multiple 465.Fl t 466arguments which are then ORed together, the user instead specifys multiple 467matching expressions joined by the pipe ( | ) character. The comma 468separated arguments within each matching expression are ANDed together, and 469then the pipe separated matching expressions are ORed together. Any 470device matching the combined expression will be displayed, if there is room 471to display it. For example: 472.Pp 473.Dl match da,scsi | cd,ide 474.Pp 475This will display all SCSI Direct Access devices and all IDE CDROM devices. 476.Pp 477.Dl match da | sa | cd,pass 478.Pp 479This will display all Direct Access devices, all Sequential Access devices, 480and all passthrough devices that provide access to CDROM drives. |
