To check a copy of a file on its originality from its installed package.

[Sthu Deus <sthu.deus@gmail.com>]

Good day.

I wonder if there is a way how I can check whither a copy of a file is
the original one from its installed package - just to make sure it is
not corrupted by an evil hand.

For example, I have

/usr/bin/sudo

that comes from its installed package

sudo

My question is, How I can find out that the /usr/bin/sudo file has not
been exchanged with another copy by some person and therefore it does
some stuff that I'm not aware of.

Thank much You for Your time.
