i am just learning shell scripting and came across some doubts as i check some possible interview questions and my doubts .
This line is of no use at all, because it contains a syntax error.
Actually yes, because it contains the same syntax error and will equally not work.
I hope this helps.

/PS: only now saw that Don already mentioned it.
actually i want to put the output of the command date into the shell variable mydate
mydate ="$(date)"
I have understood that. This line is just not producing what you want and you may want to find out why.
Intead of checking interview questions you might want to consider firing up a terminal, enter your command line and then checking what is in the mydate variable. Then you can try to make it work in the way you expected it and at the end you will have learned a valuable lesson about shell scripting - instead of checking off one more question with our answers and having it forgotten in 2 minutes.
I hope this helps.
