7.4. Nested if/then Condition Tests
Condition tests using the if/then
construct may be nested. The net result is equivalent to using the
&& compound
comparison operator.
a=3
if [ "$a" -gt 0 ]
then
if [ "$a" -lt 5 ]
then
echo "The value of \"a\" lies somewhere between 0 and 5."
fi
fi
# Same result as:
if [ "$a" -gt 0 ] && [ "$a" -lt 5 ]
then
echo "The value of \"a\" lies somewhere between 0 and 5."

Example 34-4 demonstrates a nested
if/then condition test.
