finder – take away a file which identify appears to be “.” on an SMB share?

Overview

Incorrect specification of an argument in a commandline instrument (particulars under) has led to the creation of a file actually named “.”. I’ve already discovered that immediately making an attempt to delete in Finder will set off deletion of all content material within the containing folder (happily this can be a momentary folder), however nonetheless not the “.” file itself. Furthermore, no folders containing this file might be efficiently deleted, neither with Finder nor from bash/zsh shell.

How can one truly delete (or rename) such a file?

Makes an attempt to delete from zsh

For instance:

mytmp % ls -hal
whole 65
drwx------  1 consumer  employees    16K Aug 21 11:20 .
-rwx------  1 consumer  employees     0B Aug 21 09:51 .
drwx------  1 consumer  employees    16K Aug 16 16:30 ..

mytmp % ls -aB
.   .   ..

mytmp % rm -rf '.'                   
rm: "." and ".." might not be eliminated

mytmp % cd ..

scratch % rm -rf mytmp
rm: mytmp: Permission denied

scratch % sudo rm -rf mytmp
rm: mytmp: Permission denied

I’ve additionally tried variations with out -r, since actually it’s the non-directory model that’s to be deleted.

I moreover tried the suggestion of @bmike to use the inode. Whereas we are able to determine the inode, the deletion doesn’t seem to work:

scratch % ls -ila mytmp
whole 65
8056451580272514705 drwx------  1 consumer  employees  16384 Aug 21 11:20 .
8652239633868421122 -rwx------  1 consumer  employees      0 Aug 21 09:51 .
                  2 drwx------  1 consumer  employees  16384 Aug 21 11:43 ..

scratch % discover mytmp -inum 8652239633868421122 -delete

## no change
scratch % ls -ila mytmp
whole 65
8056451580272514705 drwx------  1 consumer  employees  16384 Aug 21 11:20 .
8652239633868421122 -rwx------  1 consumer  employees      0 Aug 21 09:51 .
                  2 drwx------  1 consumer  employees  16384 Aug 21 11:43 ..

Is it actually named “.”?

@nohillside proposed to delimit the listings with x and y to see if it actually is called “.”. From bash:

bash-3.2$ for i in .*; do echo x${i}y; carried out
x.y
x.y
x..y

Seems so.

@fd0 instructed printing non-printing characters with cat -vet. From bash:

bash-3.2$ ls -1a | cat -vet
.$
.$
..$

Once more, appears identically named.

@nohillside Prompt operating a Python server from the listing and show its listing itemizing:

Further Background

The folder is on a community Quantity, format SMB (OS X).

The instrument that resulted on this was haplogrep, a Java-based CLI. One can set up it by Conda by way of

conda set up -c conda-forge -c bioconda haplogrep

The subcommand used was haplogrep classify, which has the next choices:

mytmp % haplogrep classify

I misinterpreted the “Output file location” description of the --out argument as asking for a path, main me to make use of --out . and thus leading to making a file named “.”.

Renaming

The file itself can’t be renamed in Finder or with mv, nevertheless, the containing folder might be renamed.
