Thanks for the reply and the excellent pointers. The methods suggested solve a number of problems. I wish it were otherwise, but my scripts probably have plenty of naive errors. I've gotten reasonably good at finding *a* solution to problems, but as I revisit old scripts (well, not really that old... I'm still pretty new at this, as is certainly clear...) I realize that they are far from optimal. I hope to continue discovering that, as that would mean that I'm learning better and better ways.

One general question... If I use the suggested methods:

Code:
vpass $account bash < commands

or
Code:
xargs vpass < command

does the shell have to re-read the contents of the "command" file each time, or is that somehow cached? This is a very small file, of course, with negligible read time; however, I suppose there might be cases in which re-reading could have an appreciable effect.

Again, thanks for the great reply.

dtc_setup_vps_disk

dtc_setup_vps_disks(8)					      System Manager's Manual					    dtc_setup_vps_disks(8)

NAME

       dtc_setup_disk - setup LVM disks for using it as a VM

SYNOPSIS

       dtc_setup_vps_disk.sh VPS_NUMBER HDD_SIZE SWAP_SIZE [ lvm|loopback ]

DESCRIPTION

       dtc_setup_vps_disk.sh This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.

       This script is used to create partitions to be used by a VPS later on.  It will create a normal partition that will be used as a root disk,
       and a swap partition.

       dtc_setup_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.

       If the partition(s) exists, then this script will delete it/them first.

OPTIONS

       VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group  called
       lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap.

       HDD_SIZE Size in MB of the VPS partition to create.

       SWAP_SIZE  Size in MB of the VPS swap partition to create. If the dtc-xen SOAP server is used to create the VPS, then it will create a swap
       partition of the exact same size as the memory.

       IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then	this  script  will
       create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS.

EXAMPLE

       dtc_setup_vps_disk 04 15360 256 lvm

       This will create 2 LVM partition to be used by the VPS named xen04, the first one being a root partition of 15 GB, and the second one being
       a swap partition of 256 MB.

VERSION

       This documentation describes dtc_setup_vps_disk version 0.3.15.	See http://www.gplhost.com/software-dtc-xen.html for updates.
