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 for-
mat. 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 exit-
ing 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 explana-
tions 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
FILES
