nfsconf --get [-v|--verbose] [-f|--file infile.conf] [-a|--arg subsection] section tag

nfsconf --isset [-v|--verbose] [-f|--file infile.conf] [-a|--arg subsection] section tag

nfsconf --set [-v|--verbose] [-m|--modified Modified by text] [-f|--file infile.conf] [-a|--arg subsection] section tag value

DESCRIPTION
The nfsconf command can be used to test for and retrieve configuration settings from a range of nfs-utils configuration files.

  Modes
The following modes are available:

-d, --dump
    Output an alphabetically sorted dump of the current configuration in conf file format. Accepts an optional filename in which to write the output.

-e, --entry
    retrieve the config entry rather than its current expanded value

-i, --isset
    Test if a specific tag has a value set.

-g, --get
    Output the current value of the specified tag.

-s, --set
    Update or Add a tag and value to the config file in a specified section, creating the tag, section, and file if necessary. If the section is defined as '#' then a comment is appended to the file. If a comment is set with a tag name then any exiting tagged comment with a matching name is replaced.

-u, --unset
    Remove the specified tag and its value from the config file.

OPTIONS

  Options valid in all modes

-v, --verbose
    Increase verbosity and print debugging information.

-f, --file infile
    Select a different config file to operate upon, default is /etc/nfs.conf

  Options only valid in --entry and --get and --isset modes.

-a, --arg subsection
    Select a specific sub-section

  Options only valid in --set mode.
-m, --modified "Modified by nfsconf" Set the text on the Modified date comment in the file. Set to empty to remove.

EXIT STATUS

  --isset mode
In this mode the command will return success (0) if the selected tag has a value, any other exit code indicates the value is not set, or some other error has occurred.

  all other modes
Success is indicated by an exit status of zero, any other status indicates an error. Error messages are output on stderr, and increasing verbosity will give more detailed explanations if any are available.

EXAMPLES

nfsconf -v --dump --file /tmp/testconf.conf sorted.conf
    Check a new config file for syntax errors and output a sorted version for ease of comparison with existing settings.

if ! nfsconf --isset gssd preferred-realm ; then echo 'No preferred realm configured for gss'; fi
    The tool allows for easy testing of configuration values from shell scripts, here we test if a specific value has been set.

nfsconf --file /etc/nfsmount.conf --get --arg /home MountPoint background
    Show default value for background option for NFS mounts of the /home path.

nfsconf --file /etc/nfs.conf --set nfsd debug 1
    Enable debugging in nfsd
