I stumbled across a somewhat strange behavior of tar and find no explanation for it: i was testing a DVD for read errors and thought to simply tar the content and direct the output to /dev/null:

Hello,
I'm trying to send the error output of a 'cat' operation to /dev/null like this:
cat /dirA/dirB/temp*.log > /dirA/dirB/final.log 2>/dev/null
This works perfectly in a terminal, but not when placed in a script.
If there are no files matching temp*.log the script outputs an error... (7 Replies)
How are these two different? They both prevent output and error from being displayed. I don't see the use of the "&"
echo "hello" > /dev/null 2>&1

I apologize if this question has been answered else where or is too elementary.
I ran across a KSH script (long unimportant story) that does this:

vxdestroy_lvmroot
vxdestroy_lvmroot(1M)vxdestroy_lvmroot(1M)NAME
vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group
SYNOPSIS
vxdestroy_lvmroot [-v] [-b] lvm_root_disk
DESCRIPTION
The vxdestroy_lvmroot command tears down and removes the LVM volume group associated with the specified physical disk. This is done by
removing the volumes in the volume group and then removing the volume group.
OPTIONS -b Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if the pri-
mary boot disk is not already set to this disk). The alternate boot device remains unchanged. If the -v option is also speci-
fied, the settings of the primary and alternate boot devices are displayed.
-v Outputs verbose messages including a timestamp that indicates major operations being performed.
ARGUMENTS
lvm_root_disk
Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.
EXAMPLES
This example shows the vxdestroy_lvmroot command invoked in its simpliest form:
/etc/vx/bin/vxdestroy_lvmroot c5t1d0
# /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
