Hi Alex,

Thanks for the fast check! Indeed, this seems to be a problem in the shell.

Can you share the output of the command below ('$0' stands for the 
running program, which is the shell when you are in the command-line):

$0 --version

In my case, this is GNU Bash, version 5.1.16. The default shell on most 
macOS systems is a relatively old version of Bash. It may also not be 
Bash at all, but some other shell.

To see if it is related to how the shell treats wildcards, can you try this:

imgs=$(ls outer/stamps/*.fits)
echo $imgs

Hopefully this should leave the expansion to the 'ls' tool and skip the 
shell. Let me know how it goes ;-).

Cheers,
Mohammad
