I ve been trying to use uniq -u to print the unique lines of a file with a single column
uniq -u samples3
but I get nothing! No output! The original file is pretty big (ca. 40mil lines) but still it makes no sense that i get no output...
I have already sorted it, so, what do I do wrong?
example file (only part of the original one): https://filebin.net/okmotq7t6p2g67o3
