The command below is grabing only the first load average, I would like to grab all the 3 load average. How can I change this code?
top -b -n 3 -d 1 | grep "load average" | tail -n 1 | awk '/load average:/ {printf $10}'
you should not use grep | tail | awk.
top -b -n 1 | awk '/load average/ { printf "%s %s %s\n", $10, $11, $12 }'
have also a look at w or uptime or yetis's comment.
as suggested by cas,
number of field might not be the same, depending on OS.
uptime | awk -F' *,? *' '{print $(NF-2), $(NF-1), $NF}'

nice really nice command! The output is something like this "0.10, 0.34, 0.39" would it be possible to output "0.10 0.34 0.39" without commas? – Samul Oct 31 '15 at 13:44

top -b -n 1 | awk -F' *,? *' '/load average/ { printf "%s %s %s\n", $12, $13, $14 }'. but using an ncurses program liketopfor this is silly. useuptimeor/proc/loadavginstead.uptime | awk -F' *,? *' '{print $11, $12, $13 }'– cas Nov 1 '15 at 0:21 -
@archemar - my version of top (procps-ng version 3.3.10 on debian sid) had loadavg in fields $12-$14 instead of $10-$12. – cas Nov 1 '15 at 0:23
/proc/loadavg" may be the easy answer. Isolate the 3 values withawk '{ print $1,$2,$3 }' /proc/loadavg,cut -d' ' -f-3 /proc/loadavgor other unixish other text tools... or is it essential to get them fromtop? – user62916 Oct 31 '15 at 13:28
