Nothing to do with Gluster, bash, ls or find, but w/the example.

Curious, but how difficult or problematic would it be
to allow using brace-expansion (ex. {f,x} ) as a short-hand
to test/combine file-op tests like:
Allowing:
test -{f,x} /bin/ls && ...
or
if [[ -{f,x} $file ]]; then ... ; fi
instead of:
test -f /bin/ls && test -x /bin/ls && ...

How to debug this?
Try removing all functionality in fzf that still allows you to
reproduce the bug.
'fzf' is producing "some output" which is causing confusion;
trying to narrow that down would be the likely way to proceed.
Alternatively, you might try running your combin

Do you mean '-fx' ? I assume you are meaning as an alternate?
It would be fine with me, even better on an aesthetic sense, however,
Bash already has multi-charac

All -ge -ne -eq etc. options are binary operators, while these new

Yeah, but as I said:
While "-ge $file" could probably be parsed reliably apart from
eliminate such problems.

examples for clarity)

This is indeed a quick and easy way to implement desired functionality.
Shell functions can do a lot.
Alas, they don't wor

They're not intended to work that way. If you want to test f+x+s then
you just make another function:

How many different single-ops? over 20? That's 20 factorial
combos. You wanna include that in a script?

That's what happens when you run your script in bash mode, rather than
POSIX mode.

The script used:
