The command “uniq” is a Linux command that filters and RankerX displays unique lines from a file. It removes and displays consecutive duplicate lines. The syntax for using the uniq command is as follows:
uniq [options] [input_file [output_file]]
Some common options for the uniq command include:
– -c: Precede each output line with the count of the number of times the line occurred in the input.
– -d: Only print duplicate lines, gsa ser emails omitting unique lines from the output.
– -u: Only print unique lines, omitting duplicate lines from the output.
– -i: Ignore case distinctions when comparing lines.
– -f N: Ignore the first N fields (columns) when comparing lines.
– -s N: Ignore the first N characters when comparing lines.
By default, the uniq command only works on consecutive lines. If you want to find unique lines in a file that are not necessarily consecutive, you can use the sort command to sort the lines before applying the uniq command. For example:
sort input_file | uniq
This will sort the lines in input_file and then remove any duplicate lines using the uniq command.
