I have three files testx,testy and testz all in same directory Sikh. All three files contain same data or content. The contents are:

aaabb  Aaaaa  AAAAA 



bbbcc  Bbbbb  BBBBB



ff–ff  Ccccc  CCCCC 



cccdd  Ddddd  DDDDD

Now I want to display the text containing A in all three files. What I have done so far is:

 grep '^A'*

But it does not display anything. So can anyone help me sort this out.

It doesn't show anything, because your Text has no ^A in it.

The ^ means "Beginning of line". And you have no line that begins with a Capital A.

You could search with:

grep "A" *

This will find the AAAAA in your first Line.

Or search for example:

grep "^a"

That finds the aaabb line in your text.

Grep is case sensitive.
