augmatch - inspect and match contents of configuration files
augmatch prints the tree that Augeas generates by parsing a
configuration file, or only those parts of the tree that match a certain
path expression. Parsing is controlled by lenses, many of which ship with
Augeas. augmatch to select the correct lens for a given file
automatically unless one is specified with the --lens option.
- -a, --all
- Print all tree nodes, even ones without an associated value. Without this
flag, augmatch omits these nodes from the output as they are usually
uninteresting.
- -e, --exact
- Only print the parts of the tree that exactly match the expression
provided with --match and not any of the descendants of matching
nodes.
- -I,
--include=DIR
- Add DIR to the module loadpath. Can be given multiple times. The
directories set here are searched before any directories specified in the
AUGEAS_LENS_LIB environment variable, and before the default directories
/usr/share/augeas/lenses and
/usr/share/augeas/lenses/dist.
- -l,
--lens=LENS
- Use LENS for the given file; without this option, augmatch tries to
guess the lens for the file based on the file's name and path which only
works for files in standard locations.
- -L,
--print-lens
- Print the name of the lens that will be used with the given file and
exit.
- -m,
--match=EXPR
- Only print the parts of the tree that match the path expression EXPR. All
nodes that match EXPR and their descendants will be printed. Use --exact
to print only matching nodes but no descendants.
- -r,
--root=ROOT
- Use directory ROOT as the root of the filesystem. Takes precedence over a
root set with the AUGEAS_ROOT environment variable.
- -S,
--nostdinc
- Do not search any of the default directories for lenses. When this option
is set, only directories specified explicitly with -I or specified
in AUGEAS_LENS_LIB will be searched for modules.
- -o,
--only-value
- Print only the value and not the label or the path of nodes.
- -q, --quiet
- Do not print anything. Exit with zero status if a match was found
- AUGEAS_ROOT
- The file system root, defaults to '/'. Can be overridden with the
-r command line option
- AUGEAS_LENS_LIB
- Colon separated list of directories with lenses. Directories specified
here are searched after any directories set with the -I command
line option, but before the default directories
/usr/share/augeas/lenses and
/usr/share/augeas/lenses/dist
# print the tree for /etc/exports
augmatch /etc/exports
# show only the entry for a specific mount
augmatch -m 'dir["/home"]' /etc/exports
# show all the clients to which we are exporting /home
augmatch -eom 'dir["/home"]/client' /etc/exports
The exit status is 0 when there was at least one match, 1 if there
was no match, and 2 if an error occurred.
