    if [[ ! -s $datafile ]] ; then  # no data file, skip over it?
        continue

    # run up to 5 programs against the datafile
    for prog in $prog1 $prog2 $prog3 $prog4 $prog5
    do
          "$prog" "$datafile"
    done 
done < mycontrolfile

For example, $prog3 (on first line in the input file) will evaluate to "" if it is empty. So the for loop terminates early. On the second line of datafile $prog5 is "".
Thanks for the Info and I appreciate the level of detail! Looks like a great approach that I'll have to further understand and utilize when I create the scripts (I'm in design phase right now). Curious, when you say 'read data file' in the script, is that synonomous with 'read mycontrolfile'? Or are those two different things? In addition, if you state 'prog1 prog 2' etc in the script file, how does the reference to 'someprogram1', 'anotherprogram' come into play?

	   create
	       Create the database.

	   drop
	       Drop the database.  This will ERASE ALL YOUR DATA.

	   schema

	       To use a local or supplementary datafile, specify it using the '--datadir' option below.

	   acl Initialize only the database ACLs

	       To use a local or supplementary datafile, specify it using the '--datadir' option below.

	   coredata
	       Insert data into RT's database. This data is required for normal functioning of any RT instance.

	   insert
	       Insert data into RT's database.	By default, will use RT's installation data.  To use a local or supplementary datafile, specify it

       prompt-for-dba-password

       skip-create
	   for 'init': skip creating the database and the user account, so we don't need administrator privileges

       root-password-file
	   for 'init' and 'insert': rather than using the default administrative password for RT's "root" user, use the password in this file.
