Comparison and editing of files using awk.(And also a possible bug in awk for loop?)
I have two files which I would like to compare and then manipulate in a way.
File1:
File2:
What I want is the file and the version number to be printed into a file between the two version numbers in shown in file1. So the output should be:
Also, rdcwayx identified a possible bug in the awk for loop which no one seems to have picked up on:
In the first example there should be 4 outputs, however only 3, whilst in the 2nd one we get all 4.
I have two files with field seperator as "~".
File A: 12~13~14~15
File B: 22~22~32~11
i want to calculate the difference between two files and than calculate the percentage difference and output it to a new file.
How do i do this using awk.
Also please suggest GOOD awk tutorials.
