Top Forums UNIX for Beginners Questions & Answers Bash script to get total size off of remainder calculated Post 303029601 by RudiC on Tuesday 29th of January 2019 11:40:21 AM

How about, then, making efficient use of bc and bash? Try
Code:
read VAdd OAdd HAdd TAdd <<< $(bc <<< "print $1 - $VarStandard, \" \", $2 - $OptStandard, \" \", $3 - $HomeStandard, \" \", $4 - $TmpStandard")
Delta="$(( (VAdd>0?VAdd:0) + (OAdd>0?OAdd:0) + (HAdd>0?HAdd:0) + (TAdd>0?TAdd:0) ))"
if  [ $Delta -eq 0 ]
  then  echo "No space needed"
  else  echo "$Delta extra space is needed"
fi

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

NAME
dtc_kill_vps_disk - destroy LVM disks for freeing space SYNOPSIS
dtc_kill_vps_disk VPS_NUMBER [ lvm|loopback ] DESCRIPTION
dtc_kill_vps_disk 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 delete a partitions that was used by a VPS. It will delete the normal partition that was used as a root disk, and the swap partition. dtc_kill_vps_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool. 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. 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 lvm This will delete the 2 LVM partitions that were used by the VPS named xen04, the first one being the root partition, and the second one being the swap partition. VERSION
This documentation describes dtc_kill_vps_disk See http://www.gplhost.com/software-dtc-xen.html for updates. SEE ALSO
