I tried this (used actual linefeed by pressing CTRL-V + Enter key) but still no luck. This time the output is as below:

Code:
This is a new line^Maaaa.txt
This is a new line^Mbbbb.txt
This is a new line^Mcccc.txt

I tried the solution provided by ghostdog74 and got the following error message:

awk: Cannot find or open file a.
The source line number is 1.


Code:
cat myfile

aaaa.txt
bbbb.txt
cccc.txt

Yeah that won't work... Try this then:
Code:
sed "i\
$VAR" file

Or try ghostdogs' suggestion with double quotes:
Code:
awk -vvar="$VAR" '{print var;print $0}' infile

Hi All,

Thanks for the help. I used ghostdog's solution and it worked perfectly.

Scrutinizer,

I still had problem when i used your solution. This time I got the following error:

sed: Function i cannot be parsed.

However, thanks for your time and help

Good. Regarding the sed suggestion: there should be no spaces behind the \
