augmatch − inspect and match contents of configuration files
augmatch [ OPTIONS ] FILE
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.
