Is it possible for Perl move success with response 0?
Every function in the perl File::Copy module is supposed to return 1 in case of success and 0 in case of failure.
In my case, I have noticed (using whatever logs I had) that move returns 0 even when the operation succeeds (because files are actually moved) with value of $! as No such file or directory.
Has anyone noticed such issue before?

If move returns 0, trying to rename the file failed, and then either trying to copy it failed or trying to unlink the original file after copying it failed. I don't see other possibilities, at least in File::Copy version 2.33.
You may want to just try the rename and, if needed, the copy and unlink yourself, if you need better error reporting.
What version of File::Copy are you using? What version of perl? What operating system.

2.23, 5.16.3, linux. I am not facing this issue all the time. This happens only for a few files. Anyways, I think I am gonna go with copy and unlink manually.
