язык сканирования и обработки шаблонов (pattern scanning and processing language)
Описание (Description)
Gawk is the GNU Project's implementation of the AWK programming
language. 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 and numerous GNU-
specific extensions.
The command line consists of options to gawk itself, the AWK
program text (if not supplied via the -f or --include options),
and values to be made available in the ARGC and ARGV pre-defined
AWK variables.
When gawk is invoked with the --profile option, it starts
gathering profiling statistics from the execution of the program.
Gawk runs more slowly in this mode, and automatically produces an
execution profile in the file awkprof.out when done. See the
--profile option, below.
Gawk also has an integrated debugger. An interactive debugging
session can be started by supplying the --debug option to the
command line. In this mode of execution, gawk loads the AWK
source code and then prompts for debugging commands. Gawk can
only debug AWK program source provided with the -f and --include
options. The debugger is documented in GAWK: Effective AWK
Programming.
