26 The nfsconf command can be used to test for and retrieve configuration
27 settings from a range of nfs-utils configuration files.
28 Modes
30 The following modes are available:
31 -d, --dump
33 Output an alphabetically sorted dump of the current configura‐
34 tion in conf file format. Accepts an optional filename in which
35 to write the output.
36 -e, --entry
38 retrieve the config entry rather than its current expanded value
39 -i, --isset
41 Test if a specific tag has a value set.
42 -g, --get
44 Output the current value of the specified tag.
45 -s, --set
47 Update or Add a tag and value to the config file in a specified
48 section, creating the tag, section, and file if necessary. If
49 the section is defined as '#' then a comment is appended to the
50 file. If a comment is set with a tag name then any exiting
51 tagged comment with a matching name is replaced.
52 -u, --unset
54 Remove the specified tag and its value from the config file.
55
57 Options valid in all modes
58 -v, --verbose
59 Increase verbosity and print debugging information.
60 -f, --file infile
62 Select a different config file to operate upon, default is
63 /etc/nfs.conf
64 Options only valid in --entry and --get and --isset modes.
66 -a, --arg subsection
67 Select a specific sub-section
68 Options only valid in --set mode.
70 -m, --modified "Modified by nfsconf" Set the text on the Modified date
71 comment in the file. Set to empty to remove.
72
74 --isset mode
75 In this mode the command will return success (0) if the selected tag
76 has a value, any other exit code indicates the value is not set, or
77 some other error has occurred.
78 all other modes
80 Success is indicated by an exit status of zero, any other status indi‐
81 cates an error. Error messages are output on stderr, and increasing
82 verbosity will give more detailed explanations if any are available.
83
85 nfsconf -v --dump --file /tmp/testconf.conf sorted.conf
86 Check a new config file for syntax errors and output a sorted
87 version for ease of comparison with existing settings.
88 if ! nfsconf --isset gssd preferred-realm ; then echo 'No preferred
90 realm configured for gss'; fi
91 The tool allows for easy testing of configuration values from
92 shell scripts, here we test if a specific value has been set.
93 nfsconf --file /etc/nfsmount.conf --get --arg /home MountPoint back‐
95 ground
96 Show default value for background option for NFS mounts of the
97 /home path.
