Shell Programming and Scripting

Could you provide the results/error messages? As clx points out, the -i option to grep makes case irrelevant, so it should find the keywords regardless of case. Even different white space around "task started" does not matter...

You can even leave out the "E"xtended regexp option in my proposal, it's redundant.

To me, the problem seems to be: your entries in pattern.list do NOT match the lines in sri1.log:
pattern.list:

Code:

B678C56D-96DA-4FFC-B40E-9A032A2EB12E| xengine:CERR to ECR CF

sri1.log:

Code:

B678C56D-96DA-4FFC-B40E-9A032A2EB12E          | xengine:CERR to ECR CF

So you would have to adapt either... maybe allow for some regexp in pattern.list?

Do the spaces matter during grep??

According to me the problem is in matching the word "Task started"

Since i tried matching with some other pattern in pattern.list

Do we have any other method of doing that?

Yes. In your case, grep would try to search for the exact string you would pass with-in double quotes.


I you are not sure about the spaces and cases of the string, use the regular expression search. something like below..

Code:

grep -E '[Tt]ask +[Ss]tarted' ...

If the logs/text are generated by an automated process the text MUST be same always !!

I have multiple conditions to check.
So i am using different loops to check each condition
I have 3 arrays

Code:

Remitid
Taskid
comp

I want to check file Sri1.log if it has the values stored in these arrays one by one. Means firstly for 1 value of Remitid it has 1st value of Taskid and then 1st value of comp array and then fetch value from array which has word task started

The code I have written is

Code:

while var1 in "${Remitid[@]}"
do
	for var2 in "${Taskid[@]}"
	do
		for var3 in "${comp[@]}"
		do
			while read var4
				grep 
			done < Sri1.log
		done
	done
done

But i don't know what to write in "grep". How to use all variables along with "Task started"

Please help

Try this:
dropping the

Code:

while read var4     grep      done < Sri1.log

in your last example use

Code:

grep -Ei "task started.*($var1|$var2|$var3)" sri1.log

plus cut'ting the respective fields you need. This proposal relies on "task started" being positioned left to all variable's data. If that does not work, please provide all details in your files, arrays, error msgs, what have you.

btw, your first "while" should be a "for"

I tried running the script but it is giving error

Code:

Unable to initialize device PRN

What does this mean??

WHAT? This seems to be a Windows error message to me. And - the script snippet you provided does not deal with PRN. Please show the location of occurrence in your script.
