apacheでVirtualHost一覧を出力する

Linux apache

出力の結果は同じように見える何か違いがあるとは思うけどまだ理解してないそのうち調べよう・・・と思ったら純粋にただのsynonym(同意語)だった・・・・

[~]/usr/local/apache2/bin/httpd -t -D DUMP_VHOSTS
VirtualHost configuration:
192.168.2.100:80      example.com (/usr/local/apache2/conf/httpd.conf:32)
Syntax OK

[~]/usr/local/apache2/bin/httpd -S
VirtualHost configuration:
192.168.2.100:80      example.com (/usr/local/apache2/conf/httpd.conf:32)
Syntax OK

[~]/usr/local/apache2/bin/httpd -h
Usage: /usr/local/apache2/bin/httpd [-D name] [-d directory] [-f file]
                                    [-C "directive"] [-c "directive"]
                                    [-k start|restart|graceful|graceful-stop|stop]
                                    [-v] [-V] [-h] [-l] [-L] [-t] [-T] [-S]
Options:
  -D name            : define a name for use in <IfDefine name> directives
  -d directory       : specify an alternate initial ServerRoot
  -f file            : specify an alternate ServerConfigFile
  -C "directive"     : process directive before reading config files
  -c "directive"     : process directive after reading config files
  -e level           : show startup errors of level (see LogLevel)
  -E file            : log startup errors to file
  -v                 : show version number
  -V                 : show compile settings
  -h                 : list available command line options (this page)
  -l                 : list compiled in modules
  -L                 : list available configuration directives
  -t -D DUMP_VHOSTS  : show parsed settings (currently only vhost settings)
  -S                 : a synonym for -t -D DUMP_VHOSTS
  -t -D DUMP_MODULES : show all loaded modules 
  -M                 : a synonym for -t -D DUMP_MODULES
  -t                 : run syntax check for config files
  -T                 : start without DocumentRoot(s) check

[~]# cpan


CPAN is the world-wide archive of perl resources. It consists of about
300 sites that all replicate the same contents around the globe. Many
countries have at least one CPAN site already. The resources found on
CPAN are easily accessible with the CPAN.pm module. If you want to use
CPAN.pm, lots of things have to be configured. Fortunately, most of
them can be determined automatically. If you prefer the automatic
configuration, answer 'yes' below.

If you prefer to enter a dialog instead, you can answer 'no' to this
question and I'll let you configure in small steps one thing after the
other. (Note: you can revisit this dialog anytime later by typing 'o
conf init' at the cpan prompt.)
Would you like me to configure as much as possible automatically? [yes]
