Unable to delete file via quoting, escaping or using inode

Question

I wrote a Perl script and fat-fingered the name of my output file inserting a space in the file name, so now I have my_file .txt I have tried the following with no success (and no errors reported):

rm ./my_file\ .txt
rm "./my_file .txt"
find . -inum 123 -exec rm -i {} \;

None of the above removes the file, nor do I receive an error, warning, etc. I own the file, the directory, and have the appropriate permissions. The filehandle is closed and lsof ./my_file\ .txt does not show the file in use elsewhere. My google fu has failed me, so thanks in advance for any help you can offer.

EDIT: output of stat:

$ stat my_file\ .txt
  File: `my_file .txt'

Answer 1

The most surefire way to delete things with weird names is to use find's -delete action. For example

find . -inum 16613511 -delete 

or

find . my_file?.txt -delete
