Yes, but I have never had TeX as a working command in my computers but
I had tex, pdftex, xetex, xelatex, lualatex etc. This allows me to
have e.g. Backup.sh which sets environment for making a backup copy
(attaches external disks etc.) abd then calls backup.sh which resides
in the same directory. Thus I have both Backup.sh and backup.sh in the
same directory and they are different files. Of course, I can also
connect a disk from a Windows server to my Linux computer but then
this shared disk has a case insensitive file system even in Linux.
