Hi
list files with duplicates in same directory
e.g.
house.jpg House.jpg hOUSE.jpg
I guess it needs a e[$REPLY...] clause

Assign the contents of the directory to an array and lower-case and sort
it.
local -a array
array=(*)
array=(${(Lo)array})
Now all you need to do is search for consecutive duplicate elements in
the array (exercise for the reader). If you find one, say element i,
array=((#i)${array[i]})
should collect the ones with the names that match it.

I couldn't figure out any syntactically valid way to insert (#i) in
the glob. If that were possible you wouldn't need the function and
local option.

Of course this also works.. duh :)
print -rl - *(e,'setopt nocaseglob; [[ -n $REPLY(#q[2]) ]]',)

Sorry for triple posting, the last version only "works" for external
commands, eg, when we fork before performing the glob, or it will
change the caseglob setting in the parent shell (for example when
using the print builtin), so I go back to recommending the first
version.

That's neat, but the option setting leaks out...
print -rl - *(e,'() { setopt localoptions nocaseglob; [[ -n $REPLY(#q[2]) ]] }',)
or (tcm = test case match)
tcm() {
setopt localoptions nocaseglob
[[ -n $REPLY(#q[2]) ]]
}
print -rl - *(+tcm)

your solutions do not work!?
They list all of the above files instead of just house.*

If you use a zsh from ten years ago, you don't have anonymous
functions, you also cannot use globbing inside [[ ]].
tcm() {
setopt localoptions nocaseglob
local a
a=( $REPLY([2]N) )
[[ -n $a ]]
}
*(+tcm)
this should work in ancient zsh versions too, probably. If not, should
only need minor modifications.
