  • Print the fifth column in a space separated file

awk '{print $5}' {{filename}}

  • Print the third column in a comma separated file

  • Sum the values in the first column and print the total

awk '{s+=$1} END {print s}' {{filename}}

  • Sum the values in the first column and pretty-print the values and then the total

awk '{s+=$1; print $1} END {print "--------"; print s}' {{filename}}
