Someone else can reply better than I concerning
xargs because I rarely use that utility.
FWIW: if I had your problem I would write a 5 line
PERL script that:
(1) opens the file
(2) reads each line into a $variable
(3) executes the DB command with $variable.
You can also do this with other shell languages using the same basic idea/algorithm above.
Someone familar with
PERL , for example, could write the script faster than it takes to post to the forum
because it is just a few lines of code.
Others may want to discuss your
xarg problem-solution more directly......
can you believe it?? ...... i was just making a peanut-butter-and-jelly sand' and dropped a big hunk of peanut butter on the keyboard replying to this post ....

EXAMPLES
It is frequently desirable to apply to pipelines or lists of commands. This can be done only by placing pipelines and command lists in a
single file, called a shell script. To run the script using
features apply to the entire contents of file. If the shell script file is to be executed often, the need to type can be eliminated by
setting execute permission on file. The script can also be run in the background with interrupts ignored (see sh(1)):
file typically contains normal keyboard command sequences that one would want to continue running in case the terminal disconnects, such
as:
WARNINGS
Be careful to place punctuation properly. For example, in the command form:

Be careful of where standard error is redirected. The following command may put error messages on tape, making it unreadable:
whereas

EXIT STATUS
The following exit values are returned:
The command specified by
command was found but could not be invoked
An error occurred in the nohup utility or the specified
command could not be found
Otherwise, the exit status of nohup will be that of the command specified.
