Indeed. "The dominant file systems at the time the design was done were TOPS-10, TENEX, TOPS-20, VAX VMS, AT&T Unix, MIT Multics, MIT ITS, not to mention a bunch of mainframe OS's. Some were uppercase only, some mixed, some were case-sensitive but case-translating (like CL). Some had dirs as files, some not. Some had quote chars for funny file chars, some not. Some had wildcards, some didn't. Some had :up in relative pathnames, some didn't. Some had namable root dirs, some didn't. There were file systems with no directories, file systems with non-hierarchical directories, file systems with no file types, file systems with no versions, file systems with no devices, and so on. People often critique the design now because Unix and Mac and DOS are so comparatively similar (compared to some of those others)..." -- Kent Pitman in comp.lang.lisp, https://groups.google.com/forum/#!original/comp.lang.lisp/Pl... |
