If you believe that false should be allowed read access on the fifo_file fifo_file by default.
Then you should report this as a bug.

Thanks for your thoughts.

Here's some code as observed "in the wild:"
`[[ ${#@} -ne 0 ]] && ...`
Perhaps the parser is reading this as an incomplete parameter
transformation? It seems from context that the original intent was simply...
`[[ $# -ne 0 ]] && ...`
As it happens, the effect appears to be the same either w
Hi,
I'm seeing this behavior on Fedora 38. Possibly it's just some user error
again, since i'm figuring out how to use vim and git at a slightly above

Hi,
Regarding the "Invoking Bash" page,

It might be more consistent and therefore perhaps more clear for all of the

accident.

Wow. I remember once I corrected an obvious flaw in a major project's CICD
bash scripts involving quoting and the trap builtin. You'd have thought I'd

Hi,
Please say something if this patch should be sent someplace else.
Shellmath's "runTests.sh" script returned x8 failing tests. This patch
addresses all eight errors as well as shellcheck's various complaints. The
full test suite now passes. These specific changes have been addressed:
* doc/
Testing how bash's help builtin responds to each character.
For some reason, while `help -d 'c'` prints the same thing as `help -c
'c*'` (note the asterisk), the same is not true when the character is
left-bracket: `help -c '[*'. This issue persists on bash 5.3 beta.

A surprisingly hard question. Um, well, this report was from something I

The first sentence reads, "alphabetic characters," which can imply that
wherever else in the paragraph the word "characters" is used, that the
intended meaning is "alphabetic characters," which is not the case. It can
be read as something like a
