When a file generated by a shell script is sent as a mail (not as an attachment), in MS Outlook, single lines of the file are displayed as two/three lines (as the lines are long). Is there a way to make each line to be displayed in 'single line with scroll bar' to enable viewing of the long line?
I think how it displays in the recipient's e-mail client is up to the client's settings.
Try sending the email as html, not plain text.
My html emails display as you want; my plain text emails wrap.
