awk
A versatile programming language for working on files.
- Print the fifth column in a space separated file:
awk '{print $5}' {{filename}}
- Print the second column of the lines containing "something" in a space separated file:
awk '/{{something}}/ {print $2}' {{filename}}
- Print the third column in a comma separated file:
awk -F ',' '{print $3}' {{filename}}
- 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}}
