CFAJ,
You are too gereous, writing that code!
Fantastic observations. There is more than one way to write it and more than one way to fix it! I will play around with the case and printf code just to learn it.
What I want to do is to use this scripting more and more so that I can quickly make observations like that. Push out code without breaking a sweat like you just did. and Perderabo.
I sweat over this stuff, but if I use it more, I should improve.
When we add new printers, some processes have to be recycled in the application. I wrote a script long ago to do this, but I have to edit it from one application domain to the next. I want to build these data files and set them to readonly permission so no one will delete them.
My next job is to write one to add the printer wrapping ksh around AIX smitt.
Well I probably in TMI territory now!
Thanks again!

is assigned to the first variable var, the second field to the second variable var, and so forth. If there are more fields than there are
specified var operands, the remaining fields and their intervening separators are assigned to the last var. If there are more vars than
fields, the remaining vars are set to empty strings.
The setting of variables specified by the var operands affect the current shell execution environment.
Standard input to can be redirected from a text file.
Since affects the current shell execution environment, it is usually provided as a normal shell special (built-in) command. Thus, if it is

caller's environment:
Options

EXAMPLES

do
printf "%s %s
" "$yy" "$xx"
done < input_file
