Problem in extracting data using cut/awk command
Hi Everyone,

I have a very simple problem and i am stuck in that from last 8 days. I tried many attempts, googled my query but all in vain.

I have a text file named "test.txt"
In that suppose i have contents like:

Code:
Java:
1 Object oriented programming language
2 Concepts of Abstraction and Interfaces
3 Inheritance comes into role.
4 Constructor used to initialize object.

C:
1 Procedural language
2 No inheritance
3 No constructor
4 Different scope variables are present here.

Now suppose i want to cut the whole Content of java and store it in a variable in a script and same for C and store it in another variable. Which command is suitable as i want to have output in the same format as input.


I tried cut command with output delimiter and awk command but Didnt achieve my goal. Any help highly appreciated ! Smilie

This is very close to your other request. Couldn't you apply / adapt the solutions given there?

Hi RudiC,

The solution that you gave didn't work there.So i tried to make a simple text file and try only this problem.

The solutions given there were tested on the samples provided there and DID work. Mayhap they didn't for you and / or a different setup. You'll need to adapt them, then.

My proposal to this "new" problem would be very close to the ones over there, so you'd need to reconsider adapting it.

But, as this request is nearly identical to the other one, Don Cragun's question still applies (and please make sure to answer it!):

RudiC, the awk command that you mentioned gives result:

Code:
1:Object oriented programming language 2: Concepts of Abstraction and Interfaces 3 Inheritance comes into role...... and so on

All in one line only Smilie
