How to find a specific word between two lines having same another word..
 
Hi,

First of all apologies for that poor statement I wrote - my bad english :-(

Let me elaborate in example what I exactly need.

I have a java app log file containing different exceptions.

Code:
$ vi java.log

2013-01-23 21:19:32,621 INFO [STDOUT] (my-nio-server-WorkerThread-4029) [LCDS]01/23/2013 GatewayEndpoint 'gateway-endpoint' failed to process a synchronized authentication.

I want to find how many "exception" words are there between line having "INFO" word in them.

ie. for example, in below section there are two exception errors..

Code:
2013-01-23 21:19:32,621 INFO [STDOUT] (my-nio-server-WorkerThread-4029) [LCDS]01/23/2013 GatewayEndpoint 'gateway-endpoint' failed to process a synchronized authentication.

Thanks in advance.

Ravi

Please provide a sample output file which corresponds to the sample input file already posted. That, along with your words, will help us to understand your goal.

Perhaps something like this?

Code:
awk '/INFO/ { count[++n]=0 } ; /Exception/ { count[n]++ } ; END{ for (i in count){ printf "section %d has %d exceptions\n",i,count[i] } }' | sort -k1n

I like this solution, and offer a minor improvement...
Code:
awk '/INFO/ {count[++n]=0}; /Exception/ {count[n]++};
  END{for (i=1;i<=n;i++)
  {printf "section %d has %d exceptions\n",i,count[i]}}' $InFile >$OutFile
...which produces the same result without needing the sort step.

Yeah, I should've thought of that. I hate having to fight with awk's lack of easy array control and tend towards the laziest approach. awk really needs to get a few built-in array and field range functions; splicing and sorting can be so annoying.
