|-c||Check-only mode; exit with a code of 0 if any of the variables are present in the configuration file, and 1 if there are none.|
|Specify the configuration file to read from, or "-" (a single dash) for standard input.|
|-h||Display program usage information and exit.|
|-L||Variable list mode; display the names and values of all variables in the specified section with names matching one or more specified patterns.|
|-l||List mode; display the names and values of all variables in the specified section.|
|Only display variables with if their values match the specified pattern.|
|-N||Always display the variable name along with the value.|
|-n||Never display the variable name, only the value.|
|Display this string after the variable name as a postfix.|
|Display this string before the variable name as a prefix.|
|Query for a specific type of information. For the present, the only supported value for the query argument is "sections", which lists the names of the sections defined in the configuration file.|
|-S||Quote the variable values so that the "var=value" lines may be passed directly to the Bourne shell.|
Specify the configuration section to read.
If this option is not specified, confget will use the first section found in the configuration file. However, if the configuration file contains variable definitions before a section header, confget will only examine them instead.
|-T||List the available configuration file types that may be selected by the -t option.|
|Specify the configuration file type.|
|-V||Display program version information and exit.|
|-x||Treat the patterns as regular expressions instead of shell glob patterns.|
Not taken into consideration.
If the -c option is specified, the confget utility will exit with a status of 0 if any of the specified variables exist in the config file and 1 if none of them are present.
In normal operation, no matter whether any variables were found in the configuration file or not, the confget utility exits with a status of 0 upon normal completion. If any errors should occur while accessing or parsing the configuration file, the confget utility will display a diagnostic message on the standard error stream and exit with a status of 1.
Retrieve the variable machine_id from the system section of a configuration file:
confget -f h.conf -s system machine_id
Retrieve the page_id variable from an HTTP GET request, but only if it is a valid number:
confget -f- -t http_get -x -m ^\d+$ page_id
Retrieve the variable hostname from the db section, but only if it ends in ".ringlet.net":
confget -f h.conf -s db -m *.ringlet.net hostname
Display the names and values of all variables in the system section with names beginning with "mach" or ending in "name", appending a "cfg_" at the start of each variable name:
confget -f h.conf -s system -p cfg_ -L mach* *name
Display the names and values of all variables in the system section:
confget -f h.conf -s system -l
Safely read the contents of the db section:
eval confget -f h.conf -s db -p db_ -S -l
For another way to parse INI files, see the Config::IniFiles(3) Perl module.
No standards documentation was harmed in the process of creating confget.
Please report any bugs in confget to the author.
