Any reason to not just install uuencode ?

You should be able to write an equivalent to uuencode using "iconv" with a destination character set of "uucode".
Then just add the header and trailer:

Code:

begin 644 attachment.txt
encodedtext
encodedtext
encodedtext
`
end

Dear Methyl,
Due to process and time delay constraints, we are looking to solve the issue asap with other alternate way using available commands/scripts...
Meanwhile Methyl would you please explain about the "iconv" usage in getting the file attached the mail using mailx.. and also i checked and uucode is also not available..Would be of a great help..

Methyl I also tried out the below sampling.. I received the email still with the file content in the body of the message rather than attachment...

cat FILENAME | iconv -f IBM-850 -t ISO8859-1 |mailx -s "stats" mail@address.com

What about using perl or Python

Dear Padow,

I ve not used perl before and I donot have any idea about perl scripting.
So for this case would be possible for u to lemme know with a sample perl script.. the links u had posted were helpful really, however i couldn figure how to customize it for my requirement.. would it be possible for u to help..

The requirement is to send a flat file as text file as an attachment in a mail to the recipients...

In this context, uucode is the name of a character set. It is the character set conversion used by uuencode and uudecode .
Coincidentally there is a an AIX unix command called uucode but it has nothing to do with data conversion.

The syntax for iconv is in man iconv. There is extensive background information about the various converters on the IBM website.
Help - AIX 6.1 Information Center and search for iconv .
