How detailed do you want?
You could ask top(1) to send out one pass.
For memory (actually swap) usage, you could use "swapinfo -tam".
For disk usage you can use "bdf -l".
Is this detailed enough for you?

You can have each of these commands append their output to that one file.
> $OUTFILE
top -f $OUTFILE -n 50
swapinfo -tam >> $OUTFILE
bdf -l >> $OUTFILE

do a man sa1

in that man page it will give you sa1 commands you can put in a cron file to cause sar to collect data every hour on your system.
