晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。   林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。   见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝)   既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。   南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。 .

README:

This is GNU Awk 4.2.1. It is upwardly compatible with Brian Kernighan's
version of Unix awk.  It is almost completely compliant with the
2008 POSIX 1003.1 standard for awk. (See the note below about POSIX.)

This is a bug-fix release. See NEWS and ChangeLog for details.

Work to be done is described briefly in the TODO file, which is available
only in the 'master' branch in the Git repo.

Changes in this version are summarized in the NEWS file.

Read the file POSIX.STD for a discussion of issues where the standard
says one thing but gawk does something different.

To format the documentation with TeX, use at least version 2017-09.16
of texinfo.tex. There is a usable copy of texinfo.tex in the doc directory.
You should also use at least version 6.1 of texindex and of makeinfo
from the texinfo-6.1 distribution.

INSTALLATION:

Check whether there is a system-specific README file for your system under
the `README_d' directory.  If there's something there that you should
have read and didn't, and you bug me about it, I'm going to yell at you.

See the file INSTALL for installation instructions.

If you don't have Bison, use the awkgram.c file here.  It was
generated with Bison, and has no proprietary code in it.  (Note that
modifying awkgram.y without Bison will be difficult, at best.  You might
want to get a copy of Bison from the FSF too.)

The build mechanics depend upon Bison. Also, gawk doesn't work correctly
with some versions of yacc, so just use Bison.

If you have an MS-DOS, MS-Windows, or OS/2 system, use the stuff in the `pc'
directory.  Similarly, there is a separate directory for VMS.

Appendix B of ``GAWK: Effective Awk Programming'' discusses configuration
in detail. The configuration process is based on GNU Autoconf and
Automake.

After successful compilation, do `make check' to run the test suite.
There should be no output from the `cmp' invocations except in the
cases where there are small differences in floating point values, and
possibly in the case of strftime.  There may be differences based on
installed (or not installed) locales and the quality of multibyte
character support on your system.

Several of the tests ignore errors on purpose; those are not a problem.
If there are other differences, please investigate and report the problem.

PRINTING THE MANUAL

The `doc' directory contains a recent version of texinfo.tex, which will
be necessary for printing the manual.  Use `make dvi' to get a DVI file
from the manual. In the `doc' directory, use `make postscript' to get
PostScript versions of the manual, the man page, and the reference card.
Use `make pdf' to get PDF versions of the manuals, the man page and
the reference card.

BUG REPORTS AND FIXES (Un*x systems):

Please coordinate changes through Arnold Robbins. In particular, see
the section in the manual on reporting bugs. Note that comp.lang.awk
is about the worst place to post a gawk bug report. Please, use the
mechanisms outlined in the manual.

Email should be sent to bug-gawk@gnu.org.  This is a separate mailing
list at GNU Central.  The advantage to using this address is that bug
reports are archived at GNU Central.
