"This happened at leat three times before in the past and it is
"intermittent. Almost impossible to re-create. In this script we do a
"sequential grep for a specific string from a file and check for a condition,
"this is how it looks like

"the error we recieve is 
"---------------------------------------------------
"/operator/bin/call_21[245]: test: argument expected
"ALL SQL*Loader processes completed successfully.

"
"we do not understand why this happens even though all the string we are
"grepping for are there.
"Has anyone seen anything like it before. Is the ksh buggy. This is Solaris
"2.8 env.

obviously, what's happening is that $NUM_REC is null because the
grep/cut didn't return anything.  what proof do you have that it's
always filled?

i suggest that you try running the script with -x in the shell options.
you should also try double-quoting "$NUM_REC".
