Sending attachments using email through shell script
Hi all,
I have written a shell script which sends emails with attachments to our clients. All our attachments are simple flat files (.txt format).
The script is working fine and sending the attachments to the mail-ids except that, when i am sending the attachments to non-outlook users (Like yahoo, gmail etc), i am seeing a junk character at the end of each line and the next line of file is appended to the previous line. In short all the data in the file is coming in one long line.
Here also there is a small twist. In gmail, there will be 2 options 2 download the file, View and Download. I am getting this problem only when i am downloading to the file to my local folder and viewing it.
Also when i am opening the same attachments in outlook, i can see that the data is appearing line by line as we entered it.
Kindly advise me, why this problem is occuring only when i am sending the mail to yahoo and gmail accounts. I am pasting the relavent code from my script.

have to extract these parts and decode them manually.
