brackets vs parentheses - single and double

hi, unix gurus.

i am wondering if someone can give me a clear explanation of the differneces between parentheses and brackets, both single and double.


i have heard that double parentheses (( are used for numerical expressions and that single brackets [ are used for strings. but i see very different behavior on this forum and elsewhere. i would love some clarity!


thanks for your help as usual.
