> Suppose the system administrator moved the /usr/bin directory, as

> 5.  Which files in the new /usr/lib/bin directory would be dangling

>    A.  bzcat  
> Y  B.  gunzip  
> Y  C.  gzip  
>    D.  lz  
> -  E.  uncompress  
>    F.  zgrep  
> 
> The 'test' claims that 'E' is also a correct answer. If 'E' is
> correct, then so to is 'A'.  'A' & 'E' are both wrong or right

> ./bzcat -> bzip2
> ./gunzip -> ../../bin/gunzip

>    Both gunzip & gzip would be effected by the move of /usr/bin
> 
>    Both bzcat & uncompress point to the current directory
>    Neither bzcat nor uncompress is effected by the move,
> they are either already hanging links or they are not.

> The information given conatains NEITHER bzip2 nor compress,
