<^M> is the carriage return (<CR>, 0x0D) char, and it does exactly that: it prints DB34 from your sample, then goes back to the first position in the line, and prints @example.com, overwriting the DB34.
This is frequently the problem when people work between windows and *nix environments; all DOS/windows systems use <CR><LF> line terminators while *nix use just <LF>.

Thanks for the response RudiC. Is there any other option with
Code:
tr -d '\r'

which could avoid carriage return problem?

And i didn't understand why did the linux system which i logged on remotely using putty, consider f1.txt which is inputfile in DOS format?

Use *nix compatible editors in the first place. If not possible, convert file with e.g. dos2unix, or recode / iconv. awk also can remove the \r.

Hi RudiC, i tried with dos2unix command which is available in my linux server. but didn't get expected result in the f2.txt o/p file
Code:
[linux1@XXXXXXX yyyyyy]$ dos2unix f1.txt
dos2unix: converting file f1.txt to UNIX format ...

Saying "didn't get the expected result" gives us zero useful information.

What did you get?
What did you expect?
Show us the output of the commands:
Code:
od -c your_current_script
           and
od -c /home/linux1/xxxxxxx/f1.txt

and then run your_current_script and show us any output it printed and the output of the command:
Code:
od -c /home/linux1/xxxxxxx/f2.txt
