comment What is the difference between bash and -bash?
I think it's only a matter of formatting the output. As far as I know, there's no such thing as a -bash shell, but I could be mistaken of course.

comment how to take subnet mask for an IP
Must be a misprint then. The CIDR postfix indicates the mask bits, e.g. 192.168.1.25/27 means 27 mask bits; this corresponds to the subnet mask 255.255.255.224.
