Let’s say your dataset is big in both dimensions – rows and columns. Then you want to use join. To use join, you have to sort your data first. Something along those lines: <File1.txt sort -k2,2 > File1-sorted.txt <File2.txt sort -k3,3 -S1G > File2-sorted.txt join -1 2 -2 3 File1-sorted.txt File2-sorted.txt > matches.txt The sort … Read more
