The S command scans the buffer table bits and displays and/or clears them depending on the certain criteria.
S[f|h|i|m|s|w]{-}
| - | Clears instead of displays. |
| f | Referenced bit. |
| h | Hold bit. |
| i | Iobusy bit (disk read). |
| m | Temporary mlock bit. |
| s | Suppresses detail output and shows only the total. |
| w | Write-required bit. |
The user specifies which bits to search for using the above options. When a buffer is found, it displays in a manner similar to that of the h command. The user may go backward or forward in the selection list using CTRL+P and CTRL+N. At completion, the total count of items is indicated.
