fastest way to remove duplicates.
I have searched the FAQ - by using sort, duplicates, etc.... but I didn't get any articles or results on it.
Currently, I am using:
sort -u file1 > file2 to remove duplicates. For a file size of 1giga byte approx. time taken to remove duplicates is 1hr 21 mins.
Is there any other faster way to remove duplicates? Our file sizes could get to 10 to 12 giga bytes size.
Aprpeciate any pointers.
Thanks,
Radhika.
