3 simple esxi commandline questions

[dax2]

Hello
I have 3 simple questions about ESXi-shell commands

1. how do I run a dd command and gzip the results without storing the of-file somewhere ?

/tmp # dd if=/vmfs/devices/disks/mpx.vmhba1\:C0\:T0\:L0:1 of=/tmp/dd.dump bs=1M count=20

/tmp # gzip -c dd.dump > dump.gz

instead of those 2 lines do it all in one without storing dd.dump

2. how do I create a list of all vmx-files in a datastore without also listing  *.vmxf or files that have vmx in the name like vmx-blabla.vmdk
the output must use full paths so I need something like this but without the false results

find /vmfs/volumes/datastore1/* | grep ".vmx" | grep -v ".vmxf" > vmx-files.list

3. how do I grep all vmware*.log files in a datastore for a complex string like "scsi0:0.filename = " and pipe the results in a file that lists the results like

/vmfs/volumes/datastore1/test/test.vmware.log: 2012-10-01T07:19:00.120Z| vmx| DICT          scsi0:0.fileName = WIN02.vmdk

/vmfs/volumes/datastore1/test2/test2.vmware.log: 2012-10-02T07:19:03.120Z| vmx| DICT          scsi0:0.fileName = test2.vmdk

Thanks in advance

2. does this do it ?

find /vmfs/volumes -name *.vmx > vmx-list.txt

1.

dd if=/vmfs/devices/disks/mpx.vmhba1\:C0\:T0\:L0:1  conv=sync,noerror bs=1M count=20 | gzip -c  >  /tmp/dump.gz

3.you could xargs -- find /path/to/vmfs/ -name 'vmware*.log' | xargs grep -i string

I assume this is 4.1 - I am not yet sure if ESXi has xargs

thank you both

all 3 commands work like a charm

@Sai Garimella - your command works in esxi 5.1

one more question if you dont mind ...

using find against large datastores seems to be very slow

so if I want to create a listing of vmx-files and another one for vmdk-files and one for vmsd-files should I run

find /vmfs/volumes/  -name "*.vmdk" > /tmp/vmdk.list

find /vmfs/volumes/  -name "*.vmx" > /tmp/vmx.list

find /vmfs/volumes/  -name "*.vmsd" > /tmp/vmsd.list

or something like

find /vmfs/volumes/  > /tmp/all.list
grep ".vmx" /tmp/all.list | grep -v ".vmxf" > /tmp/vmx.list
grep ".vmdk" /tmp/all.list > /tmp/vmdk.list
grep ".vmsd" /tmp/all.list  > /tmp/vmsd.list

the first option has better results but takes much longer
