3.20.7 mailutils query

The mailutils query command queries values from Mailutils configuration files. It takes one or more configuration paths (see Paths) as its arguments. On output, it displays the values it found, each value on a separate line. If the requested value is a block statement it is displayed in full. For example, if main configuration file contained:

logging {
   syslog yes;
   facility mail;
}

Then:

$ mailutils query .logging.syslog
syslog yes;
$ mailutils query .logging.syslog .logging.facility
syslog yes;
facility mail;
$ mailutils query .logging
logging {
  syslog yes;
  facility mail;
};

Several command line options allow to modify output format. The --value option instructs the command to output only values:

$ mailutils query --value .logging.syslog
yes

The --path option instructs it to print full pathnames for each value:

$ mailutils query --path .logging.syslog
logging.syslog: yes

The --program option instructs mailutils to behave as if it was called under another program name. For example, the following command:

$ mailutils query --program=pop3d .server.transcript

will return the value of the ‘.server.transcript’ statement which the pop3d utility would see.

By default, mailutils query operates on the main configuration file. Another configuration file can be supplied using the --file (-f) option:

$ mailutils query --file /usr/local/etc/file.conf .pidfile
