using OR in shell script

Question

My shell script looks something like this...

if [[ $uptime -lt 0 ]];then
some code
fi

if [[ $questions -lt 1 ]];then
some code
fi

if [[ $slow -gt 10 ]];then
some code
fi

How do I use OR and have a single if clause?

Answer 1

if [ $uptime -lt 0 -o $questions -lt 1 -o $slow -gt 10 ] ; then
    some code
fi

See man test for available syntax and options. The [ operator is just shorthand for test, so the above code is equivalent to:

if test $uptime -lt 0 -o $questions -lt 1 -o $slow -gt 10 ; then
    some code
fi
