        bash scripts: fix variable quoting issue
    
        Fixed quoting issues found by shellcheck, no feature
        change. This should fix many errors when there is space
        in any shell variables, eg. dump target's name/path/id.
    
        False positives are marked with "# shellcheck disable=SCXXXX", for
        example, args are expected to split so it should not be quoted.
    
        And replaced some `cut -d ' ' -fX` with `awk '{print $X}'` since cut
        is fragile, and doesn't work well with any quoted strings that have
        redundant space.
    
        Following quoting related issues are fixed (check the link
        for example code and what could go wrong):
