Need shell script to split line into variables

Hi,
I am needing a shell script that will help automate sending reports via email to our users.  I have everything ready except for one part.

All of the reports that we print has the email address and report name on line 2 of the report.  Like this:
                         mark@gmail.com   IC Trial Balance Report

The email address can be different for each report and the report name different as well.  There will be spaces to the left of the email address then some amount of spaces between the eamil address and the report name.  It is centered on the line.  The report is temporarily stored in a file named /var/tmp/report$$.rpt

What I need, is some code to put in a shell script that will look at line 2 of the report, find the email address and split it into one variable and the report name into another.  That way I can send the email to the email address variable and use the report name as the subject.

Maybe awk or sed?

Thanks,
Mark

The report name complicates things since it can have spaces in it.  There are probably simpler answers, but this seems to work.

eaddr=`sed -n "2s/^ *\([^ ][^ ]*\).*/\1/p" /var/tmp/report$$.rpt`

rname=`sed -n "2s/^ *[^ ][^ ]*  *\(.*\) *$/\1/p" /var/tmp/report$$.rpt`


 Basically, the first command looks for any leading spaces, followed by one or more non-spaces (the email address), and puts those non-spaces in the email address variable.  The second command looks for any leading spaces, followed by one or more non-spaces (the email address), followed by one or more spaces, and then puts the rest of the line, excluding any trailing spaces, in the report name variable.

 There are some spaces in those sed strings (two in one place and one in the rest).  If you're going to try those commands, I'd suggest you copy&paste them.

Hmm.  I've tested the sed commands, but haven't actually tested using them like that to assign values to variables (not running Unix at the moment).  If the values don't come out right, try adding/changing quotes.  Something like:

eaddr="`sed -n '2s/^ *\([^ ][^ ]*\).*/\1/p' /var/tmp/report$$.rpt`"

rname="`sed -n '2s/^ *[^ ][^ ]*  *\(.*\) *$/\1/p' /var/tmp/report$$.rpt`"
