A versatile programming language for working on files. More information: <https://github.com/onetrueawk/awk>.

  • Print the fifth column (a.k.a. field) in a space-separated file:
    awk '{print $5}' path/to/file
  • Print the second column of the lines containing "foo" in a space-separated file:
    awk '/foo/ {print $2}' path/to/file
  • Print the last column of each line in a file, using a comma (instead of space) as a field separator:
    awk -F ',' '{print $NF}' path/to/file
  • Sum the values in the first column of a file and print the total:
    awk '{s+=$1} END {print s}' path/to/file
  • Print every third line starting from the first line:
    awk 'NR%3==1' path/to/file
  • Print different values based on conditions:
    awk '{if ($1 == "foo") print "Exact match foo"; else if ($1 ~ "bar") print "Partial match bar"; else print "Baz"}' path/to/file
  • Print all lines where the 10th column value equals the specified value:
    awk '($10 == value)'
  • Print all the lines which the 10th column value is between a min and a max:
    awk '($10 >= min_value && $10 <= max_value)'
