Remove Duplicate Lines
Duplicate line removal keeps one copy of each line in a list. This tool keeps the first occurrence of every line and drops later copies, leaving the original order. Lines must match exactly, so lines that differ only in capitalization or spacing both stay, and repeated blank lines are reduced to one.
