Unique Sort (Remove Duplicates)

sort -u file.txt

Case-Insensitive Sort

sort -f file.txt

Stable Sort

sort -s file.txt
  • Maintains original order for equal elements

📊 Practical Examples

Sort CSV by Second Column

sort -t ',' -k 2 data.csv

Numeric Reverse Sort

sort -nr numbers.txt

Remove Duplicates While Sorting

sort -u data.txt

Sort Logs by Timestamp Column

sort -k 1 logs.txt

🧩 Common Use Cases

📊 Data Processing

  • Sort CSV or TSV files
  • Prepare datasets for analysis

📜 Log Analysis

  • Sort logs by time or severity

🔗 Shell Pipelines

  • Combine with:
    • cut
    • awk
    • uniq

Example:

cat data.txt | sort | uniq

⚡ Performance Tips

  • Use sort for:
    • Large datasets (optimized internally)
  • Combine with:
    • uniq for deduplication
  • Use -k carefully for correct column sorting
  • For huge files:
    • consider memory usage

⚠️ Common Mistakes

  • Sorting numbers without -n
  • Incorrect column indexing (starts from 1)
  • Forgetting delimiter in structured data
