+[[def_pathspec]]pathspec::
+ Pattern used to specify paths.
++
+Pathspecs are used on the command line of "git ls-files", "git
+ls-tree", "git grep", "git checkout", and many other commands to
+limit the scope of operations to some subset of the tree or
+worktree. See the documentation of each command for whether
+paths are relative to the current directory or toplevel. The
+pathspec syntax is as follows:
+
+* any path matches itself
+* the pathspec up to the last slash represents a
+ directory prefix. The scope of that pathspec is
+ limited to that subtree.
+* the rest of the pathspec is a pattern for the remainder
+ of the pathname. Paths relative to the directory
+ prefix will be matched against that pattern using fnmatch(3);
+ in particular, '*' and '?' _can_ match directory separators.
++
+For example, Documentation/*.jpg will match all .jpg files
+in the Documentation subtree,
+including Documentation/chapter_1/figure_1.jpg.
