Aritmethical operations
 
Friends

MRTG returns me a variable corresponding to the CPU load an it has the following appearance:

23.9590874279
5.9590874279
It does vary from 0 to 100.

How can I take only the integer part in order to do some
"if test -gt" ??

Thanks
Davi

Will this do?

% i=3.14157
% echo ${i%.[0-9]*}
3

See 'man bash' and look for parameter expansion for variations on this.
