1. large datafiles to be queried called "file.dat*" (column one is serial number, others are data)


file.dat1

rs10001 900 900 100 100
rs10002 800 300 200 100

file.dat2
rs10003 222 111 333 444
rs10004 999 121 232 434



2. small masterlist/cheatsheet called "master.list" with three columns: serial#,row#,filename

rs10001 1 file.dat1
rs10002 2 file.dat1
rs10003 1 file.dat2
rs10004 2 file.dat2


3. If I want to recover rs10001 and rs10004 data, I grep from my masterlist to create a subset of insterest called subset.txt

subset.txt
rs10001 1 file.dat1
rs10004 2 file.dat2


Now, I need to recover the original data for each serial number with the expected output:

rs10001 900 900 100 100
rs10004 999 121 232 434

Thanks,
jeeplou

corosync-objctl

COROSYNC-OBJCTL(8)					      System Manager's Manual						COROSYNC-OBJCTL(8)

NAME

       corosync-objctl - Configure objects in the Object Database

SYNOPSIS

       corosync-objctl [-c|-w|-d|-a|-t-h] <OBJECT-SPEC>...

DESCRIPTION

       corosync-objctl is used to configure objects within the object database at runtime.

OBJECT-SPEC
       There are two types of entities
	      Objects and Key=Value pairs

       Objects
	      Objects  are  container  like entities that can hold other entities.  They are specified as "objectA"."objectB".	An example is log-
	      ging.logger.

       Key=Value pairs
	      These are the entities that actually hold values	(read  database  "fields").   They  are  specified  as	object.key=value  or  just
	      object.key if you are reading.

OPTIONS

       -c     Create a new object.

       -d     Delete an existing object.

       -w     Use this option when you want to write a new value to a key.

       -a     Display all values currently available.

       -t     Track  changes  to an object and it's children. As changes are made to the object they are printed out. this is kind of like a "tail
	      -f" for the object database.

       -h     Print basic usage.

EXAMPLES

       Print the objOne object (shouldn't exist yet).
	      $ corosync-objctl objOne

       Create the objOne object.
	      $ corosync-objctl -c objOne

       Print the objOne object (empty).
	      $ corosync-objctl objOne
	      objOne

       Write two new keys to the objOne object.
	      $ corosync-objctl -w objOne.max=3000 objOne.min=100

       Print the objOne object (with the two new keys).
	      $ corosync-objctl objOne
	      objOne.min=100
	      objOne.max=3000

       Delete the objOne.min key
	      $ corosync-objctl -d objOne.min=100

       Prove that is gone.
	      $ corosync-objctl objOne
	      objOne.max=3000

       Delete the whole objOne object.
	      $ corosync-objctl -d objOne

       Prove that is gone.
	      $ corosync-objctl objOne
