merging two files using awk
Posted on 2000-02-25
Here's the problem.I have 2 files say file1 and file2.The format of the files are 10 segments(represent 1 customer information) repeating inself like
dus0101 customer number
dus0102 customer related information
dus0103 customer related information
... ...
... ...
dus0110 ...
dus0101 customer number
...
The customers in this 2 files are in asending order of customer account number.
Now i need to mearge these 2 files and create another file(say file3) depending on the customer number and the mearged file shud be in asending order of customer number.There might be same customer number in both files.If so skip that from file1 and write from file2 that customer to file3.The logic i can implement it as a c code but the requirement is to use shell script to arrive at this requirement.I can use awk script but i douth if nested awk can be used.Please let me know if you need anything else on this.Is there any other logic i can use
Thanks.
