Can't rename a file the name of which starts with a hyphen

Question

I'm trying to rename a file with a hyphen at the beginning of its name and both this:

mv -example-file-name example-file-name

and this:

mv '-example-file-name' example-file-name

result in:

mv: invalid option -- 'e'

Answer 1

Most GNU/Linux commands allow a -- option to indicate end of options so that subsequent - prefixed words are not treated as options.

  mv -- -example-file-name example-file-name

A small test

$ touch -- -example
$ ls -l -- *ample
-rw-r--r-- 1 rgb rgb 0 Nov 25 09:57 -example
$ mv -- -example example
$

Answer 2

RedGrittyBrick's answer is very good. Another option is:

mv ./-example-file-name example-file-name

A small test:

$ touch ./-example
$ ls -l ./*ample
-rw-r--r-- 1 me me 0 Nov 25 16:02 ./-example
$ mv ./-example example
$ ls -l ./*ample
-rw-r--r-- 1 me me 0 Nov 25 16:02 ./example
