DESCRIPTION
The confget utility examines a INI-style configuration file and retrieves the value of the
specified variables from the specified section. Its intended use is to let shell scripts
use the same INI-style configuration files as other programs, to avoid duplication of data.
The confget utility may retrieve the values of one or more variables, list all the variables
in a specified section, list only those whose names or values match a specified pattern
(shell glob or regular expression), or check if a variable is present in the file at all.
It has a “shell-quoting” output mode that quotes the variable values in a way suitable for
passing them directly to a Bourne-style shell.
Options:
-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.
-f filename
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.
-m pattern
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.
-P postfix
Display this string after the variable name as a postfix.
-p prefix
Display this string before the variable name as a prefix.
-q query
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.
-s section
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.
-t type
Specify the configuration file type.
-V Display program version information and exit.
-x Treat the patterns as regular expressions instead of shell glob patterns.
ENVIRONMENT
Not taken into consideration.
EXIT STATUS
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.
EXAMPLES
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 '^+$' 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`
