--all::
Show all refs found in `$GIT_DIR/refs`.
--branches::
Show branch refs found in `$GIT_DIR/refs/heads`.
--branches[=pattern]::
--tags[=pattern]::
--remotes[=pattern]::
Show all branches, tags, or remote-tracking branches,
respectively (i.e., refs found in `$GIT_DIR/refs/heads`,
`$GIT_DIR/refs/tags`, or `$GIT_DIR/refs/remotes`,
respectively).
+
If a `pattern` is given, only refs matching the given shell glob are
shown. If the pattern does not contain a globbing character (`?`,
`\*`, or `[`), it is turned into a prefix match by appending `/\*`.
--tags::
Show tag refs found in `$GIT_DIR/refs/tags`.
--remotes::
Show tag refs found in `$GIT_DIR/refs/remotes`.
--glob=pattern::
Show all refs matching the shell glob pattern `pattern`. If
the pattern does not start with `refs/`, this is automatically
prepended. If the pattern does not contain a globbing
character (`?`, `\*`, or `[`), it is turned into a prefix
match by appending `/\*`.
--show-toplevel::
Show the absolute path of the top-level directory.
