These are fortunes I've used locally, probably for decades, so there's no reason why they shouldn't be available to everyone.

FreeBSDs ps can create a dependency tree based on parent/child relationships
|
||||||
|
between processes, like this:
|
||||||
|
|
||||||
|

It is possible to get a meassure of the resident memory set:
|
||||||
|
|
||||||
|
$ vmstat -o | awk 'NR>1 { t[$7] += $1 } \
|
||||||
|
END { for (i in t) printf "%s %d\n",i,t[i] }'
|
||||||
|
|
||||||
|
The rows have the following meaning:
|
||||||
|
df = default (not assigned a specific pager)
|
||||||
|
sw = swap
|
||||||
|
df = virtual
|
||||||
|
vn = vnode
|
||||||
|
ph = heap
|
||||||
|
md = memory device
|
||||||
|
|
||||||
|
This will be reported in number of pages, so it needs to be multiplied by the
|
||||||
|
page size of the architecture which can be found via:
|
||||||
|
|
||||||
|
$ sysctl -n hw.pagesize

To establish a serial connection to anything including a USB device,
|
||||||

nothing more than cu(1) is needed:
|
||||||
|
|
||||||
|
$ cu -s 9600 -l /dev/ttyU0
