> A versatile programming language for working on files.
Print the fifth column (a.k.a. field) in a space-separated file:
awk '{print $5}' {filename}
Print the second column of the lines containing "foo" in a space-separated file:
awk '/{foo}/ {print $2}' {filename}
Print the last column of each line in a file, using a comma (instead of space) as a field separator:
awk -F ',' '{print $NF}' {filename}
Sum the values in the first column of a file and print the total:
awk '{s+=$1} END {print s}' {filename}
Print every third line starting from the first line:
awk 'NR%3==1' {filename}
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"}' {filename}
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)'
