First letter of each Word from a line
Hello All,

I am new to UNIX, how do i get the First letter of each Word from a line in shell scripting.

For Example
line = "The Jack In The Box"

I want to reterive The letters T for The, J from Jack, I from In, T from The and B from Box.

and store in another string.

Can anyone please help out.

Thanks in Advance

Rahul
