Use the AWK Command Generator at TechConverter.me to process text files, log files, and CSV data quickly without needing to memorize AWK syntax.

Task: Print columns 1 and 3 from a comma-separated file

Generated command:
  awk -F',' '{print $1, $3}' file.csv

With custom output separator:
  awk -F',' 'BEGIN{OFS="\t"} {print $1, $3}' file.csv

Print last column (NF = number of fields):
  awk -F',' '{print $NF}' file.csv

Print all columns except the first:
  awk -F',' '{$1=""; print $0}' file.csv

Task: Print lines containing "ERROR"
  awk '/ERROR/' logfile.txt

Task: Print lines where field 3 equals "FAILED"
  awk -F',' '$3 == "FAILED"' data.csv

Task: Print lines where field 2 is greater than 100
  awk -F',' '$2 > 100' data.csv

Task: Print lines matching multiple conditions
  awk -F',' '$2 > 100 && $3 == "active"' data.csv

Task: Sum all values in column 4 of a CSV

Generated command:
  awk -F',' '{sum += $4} END {print "Total:", sum}' data.csv

Calculate average:
  awk -F',' '{sum += $4; count++} END {print "Average:", sum/count}' data.csv

Find maximum value:
  awk -F',' 'NR==1{max=$4} $4>max{max=$4} END{print "Max:", max}' data.csv
