The "rename" command:

Usage: fossil mv|rename OLDNAME NEWNAME
or: fossil mv|rename OLDNAME... DIR

Move or rename one or more files or directories within the repository tree. You can either rename a file or directory or move it to another subdirectory.

The 'mv' command does NOT normally rename or move the files on disk. This command merely records the fact that file names have changed so that appropriate notations can be made at the next commit. However, the default behavior of this command may be overridden via command line options listed below and/or the 'mv-rm-files' setting.

The 'rename' command never renames or moves files on disk, even when the command line options and/or the 'mv-rm-files' setting would otherwise require it to do so.

WARNING: If the "--hard" option is specified -OR- the "mv-rm-files" setting is non-zero, files WILL BE renamed or moved on disk as well. This does NOT apply to the 'rename' command.

Options:

--soft
Skip moving files within the check-out. This supersedes the --hard option.
--hard
Move files within the check-out
--case-sensitive BOOL
Override the case-sensitive setting
-n|--dry-run
If given, display instead of run actions
