Describe the bug
Apropos the discussion at the bottom of #10557
If a file path contains glob metachars, you cannot access it from any command that takes arguemnts that are globs (unless you do extra glob quoting).
How to reproduce
Example:
The file exists, but cannot be accessed by any of the above command.
You can access it, but need to resort to quoting in the command argument:
Expected behavior
I think user is right to expect
ls,cpto be able to access the file whose name is explicitly provided. The path contains unusual, but perfectly legal chars.Further, the user is not likely to try glob quoting with
[]to workaround this issue. S/he is more likely to try string quoting with\and get frustrated that does not work.Screenshots
No response
Configuration
Additional context
Note that we have this problem with glob characters that were supported before PR #10557, and with commands that use both the new and the old glob algorithm.
What to do? For all of the commands that take a glob as argument, with the possible exception of
globcommand, I think the right thing to do is first try the arg as a literal path (e.gstatthe arg), only proceed to try it as a glob if thestatfails.The text was updated successfully, but these errors were encountered:
