GNU AWK is a pattern scanning and processing tool. It conforms to the
|
|
|
|
|
definition of the language in the POSIX 1003.1 Standard. This version in
|
|
|
|
|
turn is based on the description in The AWK Programming Language, by Aho,
|
|
|
|
|
Kernighan, and Weinberger. Gawk provides the additional features found in the
|
|
|
|
|
current version of Brian Kernighan's awk(1) and a number of GNU-specific
|
|
|
|
|
extensions.
