Choosing a sort mode

• -g: To sort scientific-notation values in the eleventh column: sort -g -k11

• What does the numeric option mean? sort -k2,2 : use the fields from #2 to #2 sort -k2n,2: sort by the numeric value of the second field

• -f: case-insensitive text comparison

• -r: reverse

• -t: set the field separator; default field handling uses whitespace

• Default lexical sorting: awk -F"\t" '{print $2}' subeset_product.txt | sort -u

  Product_1
  Product_10
  Product_2
  Product_3
  Product_4
  Product_5
  Product_6
  Product_7
  Product_8
  Product_9

  → numeric sort: awk -F"\t" '{print $2}' subeset_product.txt | sort -u -n → but here we need version sort: awk -F"\t" '{print $2}' subeset_product.txt | sort -u -V

Product_1
Product_2
Product_3
Product_4
Product_5
Product_6
Product_7
Product_8
Product_9
Product_10
