       [**-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 _
              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 _
              Select a specific sub-section

   **Options only valid in --set **mode.
### -m, --modified _
       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 com‐
              parison 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

## FILES
### /etc/nfs.conf
