Top Forums UNIX for Dummies Questions & Answers Unix History Question: Why are filenames/dirnames case sentsitive in Unix? Post 67726 by Kelam_Magnus on Saturday 26th of March 2005 12:59:44 PM

In my experience, there are very few times where I have to deal with upper case at all in Unix.

I actually prefer lower case now. I see the case sensitivity as another layer of sophistication for unixes. it offers another bit of security as well as for some convention if you wish.

I had a friend who would use Upper case for the first char of a dir name (non-os) then lower for the rest. Also, in teh case of some exe files, use ALL UPPER. For quick identification.

Upper case has its uses... not to be considered trivial.

mkmanifest - create a shell script to restore Unix filenames SYNOPSIS
mkmanifest [ files ] DESCRIPTION
Mkmanifest creates a shell script that will aid in the restoration of Unix filenames that got clobbered by the MSDOS filename restrictions. MSDOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters. The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix filenames to fit the MSDOS restrictions. EXAMPLE
I want to copy the following Unix files to a MSDOS diskette (using the mcopy command). very_long_name 2.many.dots illegal: good.c Capital Mcopy will convert the names to: very_lon illegalx good.c capital The command: mkmanifest very_long_name 2.many.dots illegal: good.c Capital > manifest would produce the following: mv very_lon very_long_name mv 2.many.dots mv illegalx illegal: mv mv capital Capital Notice that "good.c" did not require any conversion, so it did not appear in the output. Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames. SEE ALSO
