yes it will defenitely give a shock.

WHY not!!!

You will get a shock from dc source, no doubt
But only if u touches both +ve and -ve terminals.
You can also get a shock if the -ve terminal is earthed.

sorry dear frnds have  u ever tried this ????????????

who tell u that u got a shock on touching a single terminal 
of battery with ur hand.

it doesn't matter wether u r touching posiotve or negative 
terminal.

if u r touching it one by one sepratly u wouldn't get a 
shock 

u get shock only in the case when  one terminal of battery 
is connectimg to earth and ur trying to touching the other 
terminal.

yes the positive terminal of the battery act as a source 
and the earth provides the return path .
