+> Bulk Rename Utility.
+> More information: <https://github.com/neurobin/rnm>.
+
+- Replace a search string with a replacement string in filenames:
+
+`rnm -ss {{old}} -rs {{new}} {{path/to/directory}}`
+
+- Use a fixed (literal) search and replace string instead of regex:
+
+`rnm -ssf {{old}} -rs {{new}} {{path/to/files}}`
+
+- Add an auto-incremented index to filenames starting from 1:
+
+`rnm -i 1 -inc 1 -rs {{_}} {{path/to/files}}`
+
+- Rename files using a list of new names from a text file:
+
+`rnm -ns/f {{path/to/names.txt}} {{path/to/files}}`
+
+- Rename only files (ignoring directories and links):
+
+`rnm -fo -ss {{pattern}} -rs {{replacement}} {{path/to/files}}`
+
+- Sort input files by modification time before renaming:
+
+`rnm -s/mt -ss {{pattern}} -rs {{replacement}} {{path/to/files}}`
+
+- Run a simulation without making actual changes:
+
+`rnm -sim -ss {{pattern}} -rs {{replacement}} {{path/to/files}}`
+
+- Undo the last renaming operation:
+
+`rnm -u`
