With prompt:

$ rm test5

Without prompt:

$ rm -f test5

ANSWER 2

Try rm test5
(without the trailing slash).

The slash indicates that 'test5' is a directory whereas it's actually a file linking to a directory.

You can run removing the trailing slash:

$ rm test5

This will remove the file (i.e. the symlink).

Alternatively you may use unlink:

$ unlink test5

Again you must omit the trailing slash since you are attempting to unlink the symlink not the directory.

Sometimes if you use autocomplete to name the link that you want to delete you may not see a trailing slash but it's 'half there' and that invisible slash still gives the delete error when trying to remove that link.

So in that case type out character by character the link to be deleted as "test5" as eg. rm test5.
