Can grep command return word instead of complete line
Hi
Is there any way GREP command can return word and not complete line.
My file has following data:

HTML Code:
Hello Everyone I am NitinrajSrivastava
Hi Friends Welcome VrajSrivastava
I am using grep 'raj' which is returning me complete line.However I want only the word having keyword 'raj'.
Required output:
HTML Code:
NitinrajSrivastava
VrajSrivastava
and not complete line.

Hi R0H0N

Thanks for the quick reply.
However the command is not returning any row.

HTML Code:
echo 'Hi I am NitinrajSrivastava' | sed -n 's/ \([a-zA-Z]*raj[a-zA-Z]*\) /\1,/g'
</span>
