uniq

Output the unique lines from the given input or file. Since it does not detect repeated lines unless they are adjacent, we need to sort them first. More information: https://www.gnu.org/software/coreutils/uniq.

• Display each line once:
   
  sort {{file}} | uniq
   
• Display only unique lines:
   
  sort {{file}} | uniq -u
   
• Display only duplicate lines:
   
  sort {{file}} | uniq -d
   
• Display number of occurrences of each line along with that line:
   
  sort {{file}} | uniq -c
   
• Display number of occurrences of each line, sorted by the most frequent:
   
  sort {{file}} | uniq -c | sort -nr
