Awk

awk parses reports, among other text manipulation

Usage:

awk pattern {action}

\ The \ tells awk that a special character follows the slash, and to interpret it differently than regular text

Example: \t means a tab character

$ field (column) reference

Example: $2 tells awk to do something to the 2nd field (column) of the input
