Bash Version: 4.2
Patch Level: 8
Release Status: release
Description:
Bash now allows us to use negative array indexes to address array
elements relative to the end of the array:
arr=(a b c); echo "${arr[-1]}"
In line with that, I'd like to propose extending that functionality to
other operations that address array elements:
echo "${arr[@]:0:-1}" # Expected: c
echo "${arr[@]:1:-2}" # Expected: a c
