From: eregontp@... Date: 2020-10-25T12:23:15+00:00 Subject: [ruby-core:100526] [Ruby master Bug#17283] Why does Dir.glob's ** match files in current directory? Issue #17283 has been updated by Eregon (Benoit Daloze). Interestingly this behavior differs between Bash and Zsh: ``` $ tree . ��������� dir ������� ��������� subfile ��������� foo $ bash $ echo **/* dir/subfile $ zsh -f $ echo **/* dir dir/subfile foo ``` I think we cannot change the behavior for compatibility. As a fun fact, `"**"` can even match the parent directory with `FNM_DOTMATCH` (#17280). ---------------------------------------- Bug #17283: Why does Dir.glob's ** match files in current directory? https://bugs.ruby-lang.org/issues/17283#change-88149 * Author: Yanir (Yanir Name) * Status: Open * Priority: Normal * ruby -v: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- If my current directory has 1 file and 1 dir, and I use `Dir.glob("**/*")` or even just `**`, both the dir and the file would be matched. I would expect that only the dir will be matched, since the glob starts with `**`, which wants to match a directory. This is a behavior that's different from bash. In bash only the directory would be matched. Ruby: ``` Directory of C:\Users\User\z 10/24/2020 10:42 PM . 10/24/2020 10:42 PM .. 10/24/2020 10:42 PM dir 10/24/2020 10:41 PM 4 file 1 File(s) 4 bytes 3 Dir(s) 256,993,574,912 bytes free C:\Users\User\z>irb irb(main):001:0> Dir.glob("**/*") => ["dir", "file"] irb(main):002:0> Dir.glob("**") => ["dir", "file"] ``` In Bash: ``` root@debian:~/rubytest# ls -lah total 12K drwxr-xr-x 3 root root 4.0K Oct 23 17:44 . drwx------ 19 root root 4.0K Oct 23 17:43 .. drwxr-xr-x 2 root root 4.0K Oct 23 17:44 dir -rw-r--r-- 1 root root 0 Oct 23 17:44 file root@debian:~/rubytest# ls -lah **/* -rw-r--r-- 1 root root 0 Oct 23 17:44 dir/subfile ``` **I know the behavior is not meant to be 1:1 to bash**. But this is still unexpected and doesn't make sense to me. Is this intended? The documentation says: ``` ** Matches directories recursively. ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
