'git-ls-files' can use a list of "exclude patterns" when
traversing the directory tree and finding files to show when the
-flags --others or --ignored are specified.
+flags --others or --ignored are specified. gitlink:gitignore[5]
+specifies the format of exclude patterns.
-These exclude patterns come from these places:
+These exclude patterns come from these places, in order:
- 1. command line flag --exclude=<pattern> specifies a single
- pattern.
+ 1. The command line flag --exclude=<pattern> specifies a
+ single pattern. Patterns are ordered in the same order
+ they appear in the command line.
- 2. command line flag --exclude-from=<file> specifies a list of
- patterns stored in a file.
+ 2. The command line flag --exclude-from=<file> specifies a
+ file containing a list of patterns. Patterns are ordered
+ in the same order they appear in the file.
3. command line flag --exclude-per-directory=<name> specifies
a name of the file in each directory 'git-ls-files'
- examines, and if exists, its contents are used as an
- additional list of patterns.
-
-An exclude pattern file used by (2) and (3) contains one pattern
-per line. A line that starts with a '#' can be used as comment
-for readability.
-
-There are three lists of patterns that are in effect at a given
-time. They are built and ordered in the following way:
-
- * --exclude=<pattern> from the command line; patterns are
- ordered in the same order as they appear on the command line.
-
- * lines read from --exclude-from=<file>; patterns are ordered
- in the same order as they appear in the file.
-
- * When --exclude-per-directory=<name> is specified, upon
- entering a directory that has such a file, its contents are
- appended at the end of the current "list of patterns". They
- are popped off when leaving the directory.
-
-Each pattern in the pattern list specifies "a match pattern" and
-optionally the fate; either a file that matches the pattern is
-considered excluded or included. A filename is matched against
-the patterns in the three lists; the --exclude-from list is
-checked first, then the --exclude-per-directory list, and then
-finally the --exclude list. The last match determines its fate.
-If there is no match in the three lists, the fate is "included".
+ examines, normally `.gitignore`. Files in deeper
+ directories take precedence. Patterns are ordered in the
+ same order they appear in the files.
A pattern specified on the command line with --exclude or read
from the file specified with --exclude-from is relative to the
by --exclude-per-directory is relative to the directory that the
pattern file appears in.
-An exclude pattern is of the following format:
-
- - an optional prefix '!' which means that the fate this pattern
- specifies is "include", not the usual "exclude"; the
- remainder of the pattern string is interpreted according to
- the following rules.
-
- - if it does not contain a slash '/', it is a shell glob
- pattern and used to match against the filename without
- leading directories.
-
- - otherwise, it is a shell glob pattern, suitable for
- consumption by fnmatch(3) with FNM_PATHNAME flag. I.e. a
- slash in the pattern must match a slash in the pathname.
- "Documentation/\*.html" matches "Documentation/git.html" but
- not "ppc/ppc.html". As a natural exception, "/*.c" matches
- "cat-file.c" but not "mozilla-sha1/sha1.c".
-
-An example:
-
---------------------------------------------------------------
- $ cat .git/info/exclude
- # ignore objects and archives, anywhere in the tree.
- *.[oa]
- $ cat Documentation/.gitignore
- # ignore generated html files,
- *.html
- # except foo.html which is maintained by hand
- !foo.html
- $ git-ls-files --ignored \
- --exclude='Documentation/*.[0-9]' \
- --exclude-from=.git/info/exclude \
- --exclude-per-directory=.gitignore
---------------------------------------------------------------
-
-Another example:
-
---------------------------------------------------------------
- $ cat .gitignore
- vmlinux*
- $ ls arch/foo/kernel/vm*
- arch/foo/kernel/vmlinux.lds.S
- $ echo '!/vmlinux*' >arch/foo/kernel/.gitignore
---------------------------------------------------------------
-
-The second .gitignore keeps `arch/foo/kernel/vmlinux.lds.S` file
-from getting ignored.
