Do you mean that? That's not how bash works, it doesn't cut the
element, just remove the value at that index (ignore the offset-zero
vs. offset-one difference, of course):
[pws@pws-pc tmp]$ foo=(one two three)
[pws@pws-pc tmp]$ echo ${foo[*]}
one two three
[pws@pws-pc tmp]$ echo ${foo[0]}
one
[pws@pws-pc tmp]$ echo ${foo[2]}
three
[pws@pws-pc tmp]$ unset 'foo[1]'
[pws@pws-pc tmp]$ echo ${foo[1]}
[pws@pws-pc tmp]$ echo ${foo[2]}
three
