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
              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
