The "-u" option of the uniq command stands for "unique" and instructs it to generate as output only the lines which are unique in the source file. This means that lines that are not duplicated successively will be displayed. Option "-d" would display only the duplicated successive lines instead of unique lines. Option "-s" would ignore a specified number of characters while checking for duplicate lines. Option "-o" is not a valid option for the uniq command.
