Easy. Given that you didn't specify the language, the default
fallback is bash, which, short of a compiled language, is probably also
the fastest:
line=yourstring
line="${line##*load average:}"
line="${line##* }"
load="${line%%,*}"
echo "$load"
The first two patterns could be combined, but as is, they allow for
variable white space.
You get the idea for other languages: kill everything until "load
average", and after the first comma of what's left.
