Dear all. Sorry to interrupt, but I do have no idea about this
I am new developer in linux system
so I would like you guys could give me a handThanks
ok the question is
Example
a.txt > cat, dog, human, apple
b.txt > cat apple
comparing with a.txt and b.txt ………dog and human is missing on b.txt .. the output result list out : dog , humen … since b.txt is missing as comparing with a.txtHow can i develop ?
diff a.txt b.txt|tail -1|sed 's/^> //'
Thank you very much :)
