Q1: What does ${!var@} expand to in a Bash shell? A1: In Bash, ${!var@} expands to the attributes of the variable var. If var has been declared or has certain properties set (like being read-only or an integer), this parameter expansion will allow you to see those attributes directly. Q2: Can you give examples of different attributes ${!var@} might show? A2: Certainly! Here are a few scenarios: If var is readonly, ${!var@} would output r. If var is an integer, ${!var@} would output i. If var has multiple attributes (for example, both integer and exported), it would output them together, like xi.
