odd behaviour with quoted input strings

I'm working with a java-based monitoring tool (Solaris/x86) which can be configured to call a shell script when a particular event occurs. The java app sends a set of quoted strings as input to the shell script. The problem I'm running into is that the shell script, when called by the java app,...

Perl: FH and multiple writes

I found this logging subroutine on the net that I want to use but despite trying many things, I cannot figure out how to get the date in front of the logged text. Ideally what I'm looking for is a line that looks something like this: Wed Aug 20 18:17:29 PDT 2008 - my logging info here. my...

Does sync(2) block writes until completed?

Gentle readers, I am trying to observe system behavior on our RHEL 5.2 machines. I notice that, it appears to me, based on random iterations of dd if=/dev/zero of=/var/tmp/bigfile bs=1024 count=20000 ...that if the pdflush is flushing buffers at the time of my write, my write will take...

Odd behaviour with Expect password update script

Hi there. I've been forced by circumstance to write an expect script to handle password updates on a number of servers. There's a mix of Solaris 8, 9, 10, RedHat and Ubuntu. There's no chance the client will allow us to hook them up to a directory, so we have to make do. This script is mostly...

vxbootsetup

vxbootsetup(1M) 														   vxbootsetup(1M)

NAME

       vxbootsetup - set up system boot information on a Veritas Volume Manager disk

SYNOPSIS

       /etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]

DESCRIPTION

       The  vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
       disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk.  All of these volumes must
       be contiguous with only one subdisk.

       The -g option may be used to specify the boot disk group.

       If  no  medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
       be bootable.

       If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.

       vxbootsetup requires that:

       o    The root volume must be named rootvol and must have a usage type of root.

       o    The swap volume must be named swapvol and must have a usage type of swap.

       o    The volumes containing /usr and /var (if any) must be named usr and var, respectively.

       See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on  how  the
       system boots and how VxVM impacts the system boot process.  The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
       If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to  make  the
       disk bootable.

ARGUMENTS

       medianame
	    Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
