+git-diagnose(1)
+================
+
+NAME
+----
+git-diagnose - Generate a zip archive of diagnostic information
+
+SYNOPSIS
+--------
+[verse]
+'git diagnose' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+
+DESCRIPTION
+-----------
+Collects detailed information about the user's machine, Git client, and
+repository state and packages that information into a zip archive. The
+generated archive can then, for example, be shared with the Git mailing list to
+help debug an issue or serve as a reference for independent debugging.
+
+The following information is captured in the archive:
+
+ * 'git version --build-options'
+ * The path to the repository root
+ * The available disk space on the filesystem
+ * The name and size of each packfile, including those in alternate object
+ stores
+ * The total count of loose objects, as well as counts broken down by
+ `.git/objects` subdirectory
+
+This tool differs from linkgit:git-bugreport[1] in that it collects much more
+detailed information with a greater focus on reporting the size and data shape
+of repository contents.
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+ Place the resulting diagnostics archive in `<path>` instead of the
+ current directory.
+
+-s <format>::
+--suffix <format>::
+ Specify an alternate suffix for the diagnostics archive name, to create
+ a file named 'git-diagnostics-<formatted suffix>'. This should take the
+ form of a strftime(3) format string; the current local time will be
+ used.
+
+GIT

+Part of the linkgit:git[1] suite
