Need help in scripting
Hello,

In a loop I am using below command for every database

Code:
crsctl status res | grep -E "ora\.$DATABASE\.(.+)\.svc"

and below is one of the sample output
Code:
NAME=ora.sgraphut.sgraphutxdb.svc

Now I want to extract just service name out of this string (that is sgraphutxdb) please help me how do I proceed?
Additionally,if I need to pass the node name as one of the parameters while calling this script
Let's suppose the script name is test_relocate.sh and I need to execute this like below:
Code:
test_relocate.sh -n node1

Now how do I recognize this inside the script in a loop



Best regards,
Vishal

Let us consider the node name always occur at the point.

You can add this to the end
Code:
awk -F"." '{print $(NF-1)}'

so it would look like,
Code:
looop.....
NODE=$(crsctl status res | grep -E "ora\.$DATABASE\.(.+)\.svc" | awk -F"." '{print $(NF-1)}')
echo $NODE
test_relocate.sh $NODE
......loop

Thank you.
Can you please help me understand what is NF here in $(NF-1)
Code:
crsctl status res | grep -E "ora\.$DATABASE\.(.+)\.svc" | awk -F"." '{print $(NF-1)}

Adding to this, let's suppose I also want to use $nodename in this command and its value would be fetched from the arugments when this script would be called

Assuming this script name would be status_res.sh and the user needs to use arguments nodename which would give results specific to one server
Code:
status_res.sh -n node1

Now how should I read this argument internally in the script since I would be using below command in script
Code:
crsctl status res -n nodenamw| grep -E "ora\.$DATABASE\.(.+)\.svc" | awk -F"." '{print $(NF-1)}

Best regards,
Vishal

Try using
Code:
crsctl status res -n $2| ...

, as node1 is the second parameter to the script.

Old 11-27-2013
Code:
status_res.sh -n node1

Now I want to check in the code if something is next to -n, only that should be considered as nodename irrespective of the position of argument

Suggestions please.


Best regards,
Vishal

And what exactly are you trying to achieve? What's the reason for the manual service relocation?

In awk, NF is the number of fields in the current record. $(NF-1) is the last-but-one field.
