Uptime's output is one of the hardest things for a program/script to
parse. Here's a load average command (for 5 mins; replace the \2 with
\1 for 1 min. or \3 for 15 mins):

uptime | sed -e 's/.*load average: \(.*\...\), \(.*\...\), \(.*\...\)/\2/' -e 's/ //g'

And an uptime one:

uptime | sed -e 's/.* \(.* days,\)\? \(.*:..,\) .*/\1 \2/' -e's/,//g' -e 's/ days/d/' -e 's/ up //'

HTH,

PS: I didn't test these, I just found them on the Net.
