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


The following modes are available:

Output an alphabetically sorted dump of the current configuration in conf file format. Accepts an optional filename in which to write the output.
retrieve the config entry rather than its current expanded value
Test if a specific tag has a value set.
Output the current value of the specified tag.
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.
Remove the specified tag and its value from the config file.


Options valid in all modes

Increase verbosity and print debugging information.
Select a different config file to operate upon, default is /etc/nfs.conf

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

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.


--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.


Check a new config file for syntax errors and output a sorted version for ease of comparison with existing settings.
The tool allows for easy testing of configuration values from shell scripts, here we test if a specific value has been set.
Show default value for background option for NFS mounts of the /home path.
Enable debugging in nfsd
