Are you saying to me?
I'm using simple gmail.
*> *$ (( a = 2 , a > 1 && (a -= 2) || a-- )); declare -p adeclare --
a="-1"**
It was not my statement or question.
I have just answer the question being asked why
(( a = 2 , a > 1 && (a -= 2) || a-- )); gives the value of a = -1
And it was simple because the logical expression at `a > 1 && (a -= 2)`
was failed here so the OR || part has increase 0 -1 = -1
Thank you
Respectfully,
Bipul
