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." fi

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