NAME
       nfsconf - Query various NFS configuration settings

SYNOPSIS
       nfsconf --dump [-v|--verbose] [-f|--file infile.conf] [outfile]

       nfsconf --entry [--arg subsection] section tag

       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

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

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 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
