-This root governs where patterns that start with a / match (see below).
+Rsync builds an ordered list of filter rules as specified on the
+command-line. Filter rules have the following syntax:
+
+itemize(
+ it() x RULE
+ it() xMODIFIERS RULE
+ it() !
+)
+
+The 'x' is a single-letter that specifies the kind of rule to create. It
+can have trailing modifiers, and is separated from the RULE by one of the
+following characters: a single space, an equal-sign (=), or an underscore
+(_). Here are the available rule prefixes:
+
+verb(
+ - specifies an exclude pattern.
+ + specifies an include pattern.
+ . specifies a merge-file to read for more rules.
+ : specifies a per-directory merge-file.
+ ! clears the current include/exclude list
+)
+
+Note that the --include/--exclude command-line options do not allow the
+full range of rule parsing as described above -- they only allow the
+specification of include/exclude patterns and the "!" token (not to
+mention the comment lines when reading rules from a file). If a pattern
+does not begin with "- " (dash, space) or "+ " (plus, space), then the
+rule will be interpreted as if "+ " (for an include option) or "- " (for
+an exclude option) were prefixed to the string. A --filter option, on
+the other hand, must always contain one of the prefixes above.
+
+Note also that the --filter, --include, and --exclude options take one
+rule/pattern each. To add multiple ones, you can repeat the options on
+the command-line, use the merge-file syntax of the --filter option, or
+the --include-from/--exclude-from options.
+
+When rules are being read from a file, empty lines are ignored, as are
+comment lines that start with a "#".
+
+manpagesection(INCLUDE/EXCLUDE PATTERN RULES)
+
+You can include and exclude files by specifing patterns using the "+" and
+"-" filter rules (as introduced in the FILTER RULES section above). These
+rules specify a pattern that is matched against the names of the files
+that are going to be transferred. These patterns can take several forms:
+
+itemize(
+
+ it() if the pattern starts with a / then it is anchored to a
+ particular spot in the hierarchy of files, otherwise it is matched
+ against the end of the pathname. This is similar to a leading ^ in
+ regular expressions.
+ Thus "/foo" would match a file called "foo" at either the "root of the
+ transfer" (for a global rule) or in the merge-file's directory (for a
+ per-directory rule).
+ An unqualified "foo" would match any file or directory named "foo"
+ anywhere in the tree because the algorithm is applied recursively from
+ the
+ top down; it behaves as if each path component gets a turn at being the
+ end of the file name. Even the unanchored "sub/foo" would match at
+ any point in the hierarchy where a "foo" was found within a directory
+ named "sub". See the section on ANCHORING INCLUDE/EXCLUDE PATTERNS for
+ a full discussion of how to specify a pattern that matches at the root
+ of the transfer.
+
+ it() if the pattern ends with a / then it will only match a
+ directory, not a file, link, or device.
+
+ it() if the pattern contains a wildcard character from the set
+ *?[ then expression matching is applied using the shell filename
+ matching rules. Otherwise a simple string match is used.
+
+ it() the double asterisk pattern "**" will match slashes while a
+ single asterisk pattern "*" will stop at slashes.
+
+ it() if the pattern contains a / (not counting a trailing /) or a "**"
+ then it is matched against the full pathname, including any leading
+ directories. If the pattern doesn't contain a / or a "**", then it is
+ matched only against the final component of the filename.
+ (Remember that the algorithm is applied recursively so "full filename"
+ can actually be any portion of a path fomr the starting directory on
+ down.)
+
+)
+
+Note that, when using the --recursive (-r) option (which is implied by
+-a), every subcomponent of every path is visited from the top down, so
+include/exclude patterns get applied recursively to each subcomponent's
+full name (e.g. to include "/foo/bar/baz" the subcomponents "/foo" and
+"/foo/bar" must not be excluded).
+The exclude patterns actually short-circuit the directory traversal stage
+when rsync finds the files to send. If a pattern excludes a particular
+parent directory, it can render a deeper include pattern ineffectual
+because rsync did not descend through that excluded section of the
+hierarchy. This is particularly important when using a trailing '*' rule.
+For instance, this won't work:
+
+verb(
+ + /some/path/this-file-will-not-be-found
+ + /file-is-included
+ - *
+)
+
+This fails because the parent directory "some" is excluded by the '*'
+rule, so rsync never visits any of the files in the "some" or "some/path"
+directories. One solution is to ask for all directories in the hierarchy
+to be included by using a single rule: "+_*/" (put it somewhere before the
+"-_*" rule). Another solution is to add specific include rules for all
+the parent dirs that need to be visited. For instance, this set of rules
+works fine:
+
+verb(
+ + /some/
+ + /some/path/
+ + /some/path/this-file-is-found
+ + /file-also-included
+ - *
+)
+
+Here are some examples of exclude/include matching:
+
+itemize(
+ it() "- *.o" would exclude all filenames matching *.o
+ it() "- /foo" would exclude a file called foo in the transfer-root directory
+ it() "- foo/" would exclude any directory called foo
+ it() "- /foo/*/bar" would exclude any file called bar two
+ levels below a directory called foo in the transfer-root directory
+ it() "- /foo/**/bar" would exclude any file called bar two
+ or more levels below a directory called foo in the transfer-root directory
+ it() The combination of "+ */", "+ *.c", and "- *" would include all
+ directories and C source files but nothing else.
+ it() The combination of "+ foo/", "+ foo/bar.c", and "- *" would include
+ only the foo directory and foo/bar.c (the foo directory must be
+ explicitly included or it would be excluded by the "*")
+)
+
+manpagesection(MERGE-FILE FILTER RULES)
+
+You can merge whole files into your filter rules by specifying either a
+"." or a ":" filter rule (as introduced in the FILTER RULES section
+above).
+
+There are two kinds of merged files -- single-instance ('.') and
+per-directory (':'). A single-instance merge file is read one time, and
+its rules are incorporated into the filter list in the place of the "."
+rule. For per-directory merge files, rsync will scan every directory that
+it traverses for the named file, merging its contents when the file exists
+into the current list of inherited rules. These per-directory rule files
+must be created on the sending side because it is the sending side that is
+being scanned for the available files to transfer. These rule files may
+also need to be transferred to the receiving side if you want them to
+affect what files don't get deleted (see PER-DIRECTORY RULES AND DELETE
+below).
+
+Some examples:
+
+verb(
+ . /etc/rsync/default.rules
+ : .per-dir-filter
+ :n- .non-inherited-per-dir-excludes
+)
+
+The following modifiers are accepted after the "." or ":":
+
+itemize(
+ it() A "-" specifies that the file should consist of only exclude
+ patterns, with no other rule-parsing except for the list-clearing
+ token ("!").
+
+ it() A "+" specifies that the file should consist of only include
+ patterns, with no other rule-parsing except for the list-clearing
+ token ("!").
+
+ it() A "C" is a shorthand for the modifiers "sn-", which makes the
+ parsing compatible with the way CVS parses their exclude files. If no
+ filename is specified, ".cvsignore" is assumed.
+
+ it() A "e" will exclude the merge-file from the transfer; e.g.
+ ":e_.rules" is like ":_.rules" and "-_.rules".
+
+ it() An "n" specifies that the rules are not inherited by subdirectories.
+
+ it() An "s" specifies that the rules are split on all whitespace instead
+ of the normal line-splitting. This also turns off comments. Note: the
+ space that separates the prefix from the rule is treated specially, so
+ "- foo + bar" is parsed as two rules (assuming that "-" or "+" was not
+ specified to turn off the parsing of prefixes).
+)
+
+Per-directory rules are inherited in all subdirectories of the directory
+where the merge-file was found unless the 'n' modifier was used. Each
+subdirectory's rules are prefixed to the inherited per-directory rules
+from its parents, which gives the newest rules a higher priority than the
+inherited rules. The entire set of per-dir rules is grouped together in
+the spot where the merge-file was specified, so it is possible to override
+per-dir rules via a rule that got specified earlier in the list of global
+rules. When the list-clearing rule ("!") is read from a per-directory
+file, it only clears the inherited rules for the current merge file.
+
+Another way to prevent a single per-dir rule from being inherited is to
+anchor it with a leading slash. Anchored rules in a per-directory
+merge-file are relative to the merge-file's directory, so a pattern "/foo"
+would only match the file "foo" in the directory where the per-dir filter
+file was found.
+
+Here's an example filter file which you'd specify via --filter=". file":
+
+verb(
+ . /home/user/.global-filter
+ - *.gz
+ : .rules
+ + *.[ch]
+ - *.o
+)
+
+This will merge the contents of the /home/user/.global-filter file at the
+start of the list and also turns the ".rules" filename into a per-directory
+filter file. All rules read-in prior to the start of the directory scan
+follow the global anchoring rules (i.e. a leading slash matches at the root
+of the transfer).
+
+If a per-directory merge-file is specified with a path that is a parent
+directory of the first transfer directory, rsync will scan all the parent
+dirs from that starting point to the transfer directory for the indicated
+per-directory file. For instance, here is a common filter (see -F):
+
+verb(
+ --filter=': /.rsync-filter'
+)
+
+That rule tells rsync to scan for the file .rsync-filter in all
+directories from the root down through the parent directory of the
+transfer prior to the start of the normal directory scan of the file in
+the directories that are sent as a part of the transfer. (Note: for an
+rsync daemon, the root is always the same as the module's "path".)
+
+Some examples of this pre-scanning for per-directory files:
+
+verb(
+ rsync -avF /src/path/ /dest/dir
+ rsync -av --filter=': ../../.rsync-filter' /src/path/ /dest/dir
+ rsync -av --fitler=': .rsync-filter' /src/path/ /dest/dir
+)
+
+The first two commands above will look for ".rsync-filter" in "/" and
+"/src" before the normal scan begins looking for the file in "/src/path"
+and its subdirectories. The last command avoids the parent-dir scan
+and only looks for the ".rsync-filter" files in each directory that is
+a part of the transfer.
+
+If you want to include the contents of a ".cvsignore" in your patterns,
+you should use the rule ":C" -- this is a short-hand for the rule
+":sn-_.cvsignore", and ensures that the .cvsignore file's contents are
+interpreted according to the same parsing rules that CVS uses. You can
+use this to affect where the --cvs-exclude (-C) option's inclusion of the
+per-directory .cvsignore file gets placed into your rules by putting a
+":C" wherever you like in your filter rules. Without this, rsync would
+add the per-dir rule for the .cvignore file at the end of all your other
+rules (giving it a lower priority than your command-line rules). For
+example:
+
+verb(
+ cat <<EOT | rsync -avC --filter='. -' a/ b
+ + foo.o
+ :C
+ - *.old
+ EOT
+
+ rsync -avC --include=foo.o -f :C --exclude='*.old' a/ b
+)
+
+Both of the above rsync commands are identical. Each one will merge all
+the per-directory .cvsignore rules in the middle of the list rather than
+at the end. This allows their dir-specific rules to supersede the rules
+that follow the :C instead of being subservient to all your rules. (The
+global rules taken from the $HOME/.cvsignore file and from $CVSIGNORE are
+not repositioned from their spot at the end of your rules, however -- feel
+free to manually include $HOME/.cvsignore elsewhere in your rules.)
+
+manpagesection(LIST-CLEARING FILTER RULE)
+
+You can clear the current include/exclude list by using the "!" filter
+rule (as introduced in the FILTER RULES section above). The "current"
+list is either the global list of rules (if the rule is encountered while
+parsing the filter options) or a set of per-directory rules (which are
+inherited in their own sub-list, so a subdirectory can use this to clear
+out the parent's rules).
+
+manpagesection(ANCHORING INCLUDE/EXCLUDE PATTERNS)
+
+As mentioned earlier, global include/exclude patterns are anchored at the
+"root of the transfer" (as opposed to per-directory patterns, which are
+anchored at the merge-file's directory). If you think of the transfer as
+a subtree of names that are being sent from sender to receiver, the
+transfer-root is where the tree starts to be duplicated in the destination
+directory. This root governs where patterns that start with a / match.
Because the matching is relative to the transfer-root, changing the
trailing slash on a source path or changing your use of the --relative
option affects the path you need to use in your matching (in addition to
changing how much of the file tree is duplicated on the destination
-system). The following examples demonstrate this.

-Note also that the --include and --exclude options take one pattern

-The patterns can take several forms. The rules are:

- On the other hand, "foo" would match any file called "foo"
- anywhere in the tree because the algorithm is applied recursively from

+Without a delete option, per-directory rules are only relevant on the

-before the --exclude='*' rule). Another solution is to add specific

+However, if the merge files are not a part of the transfer, you'll need to

- + /some/path/this-file-is-found
- + /file-also-included
- - *
+ rsync -av --filter=': .rules' --filter='. /my/extra.rules'
+ --delete host:src/dir /dest
)
-Here are some examples of exclude/include matching:
+In the above example the extra.rules file can affect both sides of the

+merged from the .rules files because they were specified after the
+per-directory merge rule.
-itemize(

+In one final example, the remote side is excluding the .rsync-filter
