"echo always returns zero" is the rule I was looking for, when I couldn't even think of it!
I have implemented your suggested code, but /home/jj/Documents/cirrhus9/Accounts/Norveld/3WeekTest/norveld.test had an apache entry. A typo probably prevented the email from being sent.

The extra "fi" was probably a bad hack at some ! logic snippet I had since removed... I dunno, I tend to "hack now, debug during-run" (complete with "set -x" statement.)

Since this post, I reviewed Chapter 6 of "Linux Shell Script Programming" by Todd Meadors - Copyright 2003) where it illustrated a clue...
Code:
dir1=`pwd`

on Page 215

I will change some detail in your code and watch the inbox!

Thanks for the code and have a Prosperous New Year.

Edit:
Changed temp=$(curl -Is http://xxx.xxx.xx.xx | \grep -E '^Server' | cut -c9-) for 7 passes and no email. (I used the wrong IP)...

slacon

slacon.f(3)							      LAPACK							       slacon.f(3)

NAME

       slacon.f -

SYNOPSIS

   Functions/Subroutines
       subroutine slacon (N, V, X, ISGN, EST, KASE)
	   SLACON

Function/Subroutine Documentation
   subroutine slacon (integerN, real, dimension( * )V, real, dimension( * )X, integer, dimension( * )ISGN, realEST, integerKASE)
       SLACON

       Purpose:

	    SLACON estimates the 1-norm of a square, real matrix A.
	    Reverse communication is used for evaluating matrix-vector products.

       Parameters:
	   N

		     N is INTEGER
		    The order of the matrix.  N >= 1.

	   V

		     V is REAL array, dimension (N)
		    On the final return, V = A*W,  where  EST = norm(V)/norm(W)
		    (W is not returned).

	   X

		     X is REAL array, dimension (N)
		    On an intermediate return, X should be overwritten by
			  A * X,   if KASE=1,
			  A**T * X,  if KASE=2,
		    and SLACON must be re-called with all the other parameters
		    unchanged.

	   ISGN

		     ISGN is INTEGER array, dimension (N)

	   EST

		     EST is REAL
		    On entry with KASE = 1 or 2 and JUMP = 3, EST should be
		    unchanged from the previous call to SLACON.
		    On exit, EST is an estimate (a lower bound) for norm(A).

	   KASE

		     KASE is INTEGER
		    On the initial call to SLACON, KASE should be 0.
		    On an intermediate return, KASE will be 1 or 2, indicating
		    whether X should be overwritten by A * X  or A**T * X.
		    On the final return from SLACON, KASE will again be 0.
