conf-tool

Utility for manipulating INI-style config files from the command line. May be useful for scripting.

Usage:
  conf-tool [OPTION...] FILE [KEY [VALUE]]

Tool for parsing config files.

Help Options:
  -h, --help        Show help options

Application Options:
  -s, --section     Config section
  -r, --remove      Remove the specified key or section
  -q, --quiet       Don't print errors

If no key is specified, lists the keys. If neither key or section is specified, lists sections in the config file. If the key is specified but the section is not, the first section is used, which may be convenient if there's only one section in the config file.

Special file name - means standard input.

If standard input is modified, the modified version of the input config is dumped to standard output. That can be used for piping. Although it wouldn't be real piping because the whole thing is first sucked in, then modified and only then sent to standard output. Config files are usually quite small, though, so it shouldn't really matter.
