-s N – -skip-chars(N) : It doesn’t compare the first N characters of each line while determining uniqueness.-i – -ignore case : By default, comparisons done are case sensitive but with this option case insensitive comparisons can be made.-f N – -skip-fields(N) : It allows you to skip N fields(a field is a group of characters, delimited by whitespace) of a line before determining the uniqueness of a line.separate : Insert a blank line between each set of duplicated lines.prepend : Insert a blank line before each set of duplicated lines.none : Do not delimit duplicate lines at all.-D – -all-repeated : It prints all duplicate lines and METHOD can be any of the following:.-d – -repeated : It only prints the repeated lines and not the lines which aren’t repeated.-c – -count : It tells how many times a line was repeated by displaying a number as a prefix with the line.The content in the file must be therefore sorted before using uniq or you can simply use sort -u instead of uniq command. Note: uniq isn’t able to detect the duplicate lines unless they are adjacent to each other.
