Dear Developers,

I have found a strange behavior when saving files through the chimeraX command line. Essentially, file naming does not seem to be properly sensitive to capitalization. For example, when I am trying to save a file called “chain_A.pdb” and then another file called “chain_a.pdb”, “chain_A.pdb” will be overwritten with the contents of “chain_a.pdb”. It also does not matter if I am saving a pdb file or a log file.  If “chain_A.pdb” does not exist, then “chain_a.pdb” will be correctly saved with as a lowercase a.

Details: version 1.6.1 (2023-05-09)

OS: MacOS Catalina Version 10.15.7

Would be great if this could be fixed : )

Many thanks in advance,

Matthias
