i wanted to delete all duplicate lines from .bash_history and keep the order of the other lines.
the command cat's the file and adds line numbers, then sorts by the second column. afterwards uniq omits repeated lines, but skips the first field (the line number). then it sorts by the line numbers and at the end cuts the numbers off.
