What is the difference between [ ] and [[ ]] for conditional tests?
In Bash scripts, [] is synonymous with the test command, suitable for portability across shells; [[]] is the Bash keyword, providing more powerful and secure features. 1.[] variables need to be strictly referenced to avoid errors, while [[]] is more tolerant to unreferenced variables; 2.[[]] supports regular expression matching (=~) and wildcard pattern matching (==), while [] does not support it; 3.[[]] allows the use of && and || combination conditions without additional brackets; 4. If cross-platform compatibility is required, [] should be used. If it is for Bash, it is recommended to use [[]] for clearer syntax and advanced features.
