Yes - multiply by 100 would be fine -
Just remember you have to multiply both values.
how - heh, heh, heh.... Well , you can do it with a sed script.
Time to read the bash man page....
And as always - theres more than one way to do it.
hmm - does shell math work on floats ? Nope.
But if we assume that loadavg numbers ALWAYS have two digits to the
right of the decimal point then an edit script can do the job for us.
Its not elegant but it may work.....
load=`cat /proc/loadavg | awk '{print $1}' | sed -e 's/\.//'`
may work....
