How can I find the unique lines and remove all duplicates from a file? My input file is
1 1 2 3 5 5 7 7 I would like the result to be:
2 3 sort file | uniq will not do the job. Will show all values 1 time

The uniq command is used to remove duplicate lines from a text file in Linux. By default, this command discards all but the first of adjacent repeated lines, so that no output lines are repeated. Optionally, it can instead only print duplicate lines. For uniq to work, you must first sort the output.
uniq has the option you need:
-u, --unique only print unique lines $ cat file.txt 1 1 2 3 5 5 7 7 $ uniq -u file.txt 2 3 Use as follows:
sort < filea | uniq > fileb If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
