awk = Aho, Weinberger, and Kernighan
$0 = whole line $1 = first field $2 = second field [...] $NF = last field FS = field separator, default FS=\s+ OFS = output field seperator RS = record (line) separator ORS = output record seperator NR = number of records (counter from 1 to n) NF = total number of fields FILENAME = name of the current input file FNR = number of records relative to the current input file match() -> RSTART = where the pattern starts -> RLENGTH = the length of the pattern
