My First Time with Awk

Posted by Boy Sandy Gladies Arriezona on July 30, 2015

Tonight we’ll talk about Awk. Actually, I’ve know it for a long time but I never had any chance to explore it. A few days ago, I need to remove some duplicate lines from a file BUT it should not be sorted. We can also use sort and uniq, but it will end up sorted before we got an actual result. I’m using this kind of script to remove it:

$ awk '!x[$0]++' test_file.log > result_file.log

How is it? Interested to learn Awk even more?
