Top Forums UNIX for Dummies Questions & Answers Unix History Question: Why are filenames/dirnames case sentsitive in Unix? Post 66444 by locustfurnace on Monday 14th of March 2005 01:03:59 PM

I think the reason was because in the real world, there is a difference in name conventions. A is different than a.
Case sensitivity does give more security to passwords, by allowing for more combinations.

I personally prefer case sensitivity, it allows me to have many files, with the same name in a folder, such as Resume, resume. I can have all folders in proper case while files can be all lowercase, allows me to have more control over my filesystem. I believe under DOS/Windows, you could only have a single file named Resume, be it a folder or a file, but not both in the same directory. Unless you add differences to the name.

This may or may not give some help:

NAME
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 prn.dev Capital Mcopy will convert the names to: very_lon 2xmany.dot illegalx good.c xprn.dev capital The command: mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest would produce the following: mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv xprn.dev prn.dev 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
