Because you are still using redirection.  Don't.  Redirection is all 
this stuff '> /QSYS.LIB/TESTDP.LIB/Z28IFS1P.FILE/Z28IFS1P.MBR'

Perhaps you haven't used OVRDBF before.  Here is a very brief 
explanation.  Here is a sample: OVRDBF FILEX FILEY This tells all 
programs that follow to use FILEY any time they refer to FILEX.  If you 
have an RPG program that has FFILEX IPE..., when the program runs, OS400 
will see that the program wants FILEX and change the reference to FILEY 
because of the override.

In the case of QSH, there is a built-in file called STDOUT.  For our 
purposes, we can think of STDOUT as the terminal window.  This is not 
very precise, but it'll do for now.  Using the LS program as our 
example, you can think of LS as having an F spec like this: FSTDOUT O... 
 So when you do LS -C blahblah, the LS program opens up STDOUT and does 
a WRITE to put the listing in that file.  In your process, you don't 
want to send the LS output to that file -- you want it to go to some 
file in QTEMP.  So you need an override.

The file you are overriding is the one on the F spec - in this case, the 
internal file STDOUT.  The file you are sending it to is in QTEMP, in 
this case, QTEMP/Z28IFS1P.

Line 14800 needs to change to reflect that you are overriding STDOUT.
Line 14900 needs to just let the output go to STDOUT, that is, DON'T use 
any redirection at all.

When 14900 executes, LS will try to open STDOUT, but OS400 sees that 
14800 has an OVRDBF for STDOUT, so instead of opening STDOUT, OS400 will 
open QTEMP/Z28IFS1P.

Hope that helps.

Good reading is any Unix/Linux primer (for redirection), and the 
Database Programming guide in the Infocenter (for file overrides.)
