G'day rammohan,

How many times have you been pointed to perlintro? This explains how to read from a filehandle! Are you simply refusing to read this documentation? [That's not a rhetorical question. I'd really like to know.]

You were also shown how to do this when you asked "how read data from file" and again, three days later, when you asked "How to perform single operation to each line in file".

I have downvoted your post.
