Uptime and ps aux|head -5 1

[loloman]

I want to do a shell who scan my server with uptime
and when uptime load average > 4, i want to write
the result of ps aux|head -5 in a file
for ex :
uptime
11:36 up 4 days, 12:26, 51 users, load average: 1.40, 1.03, 0.84

if uptime | awk -F" " '{print $10}' > 4 then
ps aux|head -5 > log

Try something like this :
[tt]
uptime | awk '{ sub(/,$/,"",$(NF-2));if ($(NF-2)>4.) exit 1 }' || ps aux|head -5 > log
[/tt]
