Remove duplicate lines from a list
Paste the list into a text file and run sort -u, which sorts it and keeps each line once. To keep the original order, awk "!seen[$0]++" drops repeats without sorting.
How
Sorted, each line once:
sort -u list.txt > clean.txtOriginal order, each line once:
awk '!seen[$0]++' list.txt > clean.txt“Apple” and “apple” count as different lines. Add -f to sort (sort -uf) to treat them as the same.
