Hi,

As far as i understand, u don't need concatenation. What u need is put that variable into the file and send mail... Then the following will help:
Taking ur example:
File - abc.txt
Variable - x

Code:

echo $x >> abc.txt
mail balireddy_77 < abc.txt

Note: In the above,i presume ur unix account username is balireddy_77

if you need them side by side and has a single line in file, try:

echo "${X}`cat abc.txt`" | mail someone@host

if your file has more than one line and you want to send an email for each one, try:

while read MYLINE
do
echo "${X}${MYLINE}" | mail someone@host
done < abc.txt
