$ inside a (( )) block is redundant. So are mathematical assignments outside it.
most times your are right.but some older version of sh(like ash , that is usually not Posix compliant on many systems) your syntax is invalid.
[[ *maybe it is various of evulation expression bug of a ash.]]
(so its meant some older versions of (bourne) sh(s) like (0.38) has it, and i cannot test newer version ash(0.4 or newer if there is) so ash is not compability to SUSv3.
actually aritmetic expansion is defined for SUSv3
`Arithmetic Precision and Operations`
in Introduction
`2.6.4 Arithmetic Expansion`
in Shell Command Language]
now lets look at the belows..
[not expanded values before aritmetic expression]
it is required a `$` before variables
in sh another interesting issue
--try 1
--try 2 --try 3 is like OK , but?
but is not.
