Read Embedded Newline characters with read (builtin) in KSH93
Hi Guys,

Happy New Year to you all!

I have a requirement to read an embedded new-line using KSH's read builtin.
Here is what I am trying to do:

Code:
run_sql "select guestid, address, email from guest" | while read id addr email
do
   ## Biz logic goes here
done

I can take care of any embedded spaces by escaping them with a '\' in the run_sql utility and read would parse the value correctly.
However, address field can have embedded new line characters. Is there an escape sequence I can use to encode any embedded newlines, so the read command would store the new-line character in 'addr' variable?
I have tried '\n', but read doesn't recognize that escape-sequence.

Is there an option in read to accept embedded newlines? Or is there another builtin that can be used for this purpose?

Any help would be appreciated!

tartdates(5)						      LinuxTaRT Special Dates						      tartdates(5)

NAME

       tartdates - Special date configuration for LinuxTaRT

DESCRIPTION

       LinuxTaRT uses a configuration file called specialdates to enable the user to display a specific tagline on certain special dates. The name
       and location of this file is specified in the LinuxTaRT configuration file ~/.tartrc, but is usually:

       ~/.tartdates

PARAMETERS

       Each line of the special date file consists of a day of the year expressed as a two digit month, a forward-slash (/), a two digit  date,  a
       colon (:) and a line of text.

       mm/dd:tagline text

       Any line that does not conform to this specification will be treated as a comment.  Comments may also be specified by prefixing text with a
       # symbol. Using this method, you can place a comment behind a date line.

EXAMPLES

       01/01:Happy New Year!!

       Will use "Happy New Year!!" as the tagline when the date is January 1st.

       12/25:Merry Christmas to all!

       Displays "Merry Christmas to all!" as your tagline on Christmas day.

FILES

       ~/.tartdates
