+Listing files in a snapshot
+===========================
+
+To get a list of the files in a specific snapshot you can use the ``ls`` command:
+
+.. code-block:: console
+
+    $ restic ls 073a90db
+
+    snapshot 073a90db of [/home/user/work.txt] filtered by [] at 2024-01-21 16:51:18.474558607 +0100 CET):
+    /home
+    /home/user
+    /home/user/work.txt
+
+The special snapshot ID ``latest`` can be used to list files and directories of the latest snapshot in the repository.
+The ``--host`` flag can be used in conjunction to select the latest snapshot originating from a certain host only.
+
+.. code-block:: console
+
+    $ restic ls --host kasimir latest
+
+    snapshot 073a90db of [/home/user/work.txt] filtered by [] at 2024-01-21 16:51:18.474558607 +0100 CET):
+    /home
+    /home/user
+    /home/user/work.txt
+
+By default, ``ls`` prints all files in a snapshot.
+
+File listings can optionally be filtered by directories. Any positional arguments after the snapshot ID are interpreted
+as absolute directory paths, and only files inside those directories will be listed. Files in subdirectories are not
+listed when filtering by directories. If the ``--recursive`` flag is used, then subdirectories are also included.
+Any directory paths specified must be absolute (starting with a path separator); paths use the forward slash '/'
+as separator.
+
+.. code-block:: console
+
+    $ restic ls latest /home
+    
+    snapshot 073a90db of [/home/user/work.txt] filtered by [/home] at 2024-01-21 16:51:18.474558607 +0100 CET):
+    /home
+    /home/user
+
+.. code-block:: console
+
+    $ restic ls --recursive latest /home
+
+    snapshot 073a90db of [/home/user/work.txt] filtered by [/home] at 2024-01-21 16:51:18.474558607 +0100 CET):
+    /home
+    /home/user
+    /home/user/work.txt
+
+To show more details about the files in a snapshot, you can use the ``--long`` option.  The colums include
+file permissions, UID, GID, file size, modification time and file path. For scripting usage, the
+``ls`` command supports the ``--json`` flag; the JSON output format is described at :ref:`ls json`.
+
+.. code-block:: console
+
+    $ restic ls --long latest
+
+    snapshot 073a90db of [/home/user/work.txt] filtered by [] at 2024-01-21 16:51:18.474558607 +0100 CET):

+NCDU (NCurses Disk Usage) is a tool to analyse disk usage of directories. The ``ls`` command supports
+outputting information about a snapshot in the NCDU format using the ``--ncdu`` option.
+
+You can use it as follows: ``restic ls latest --ncdu | ncdu -f -``
