Full Discussion: delete files except most recent
Top Forums Shell Programming and Scripting delete files except most recent Post 75711 by ST2000 on Tuesday 21st of June 2005 02:33:08 PM

Thanks for all the posts.

Each file is about 500mb. If the delete job kicks off and if there is a file written at that time, linux does not know what to do and locks that space off. Say 200 mb is written when delete kicks off, that 200mb is gone from archive filesystem and in a week's time it reduces to nothing and will not last even an hour. I have to bounce db to clear up pending archives. Instead i want a modification to my script to preserve the last file and delete all.

Anyway i modified the script adding a variable which greps for last file and delete using grep -v of that last file. It was just one more line to my existing script.

Thanks again

dtc_kill_vps_disk

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.
