What are some of the differences between the file system concept of Linux and that of other operating systems?

What will be an ideal response?


The file system concept of Linux (and, in general, of all UNIX systems) is considerably different than that of other operating systems:

• Files in the file systems can be spread out over several devices. Each file system can be "mounted" any place in the directory hierarchy. With other file systems, each file system is placed on the same level, at the top. With Linux, the file systems can be placed at lower levels of the directory structure.

• A filename in Linux can be up to 255 characters long. It can contain special characters ("_" or "%", for example).

• Certain characters (the dollar sign "$", the semicolon ";", or the space, for example) have a special significance for shells, such as Bash. If you want to use one of these characters without the associated special meaning, the character must be preceded by a "\" (backslash) to mask (switch off) its special meaning.

• You can use umlauts, letters with diacritical marks, or other language-specific characters.

• Linux differentiates between upper-case and lower-case letters. For example, the file names Invoice, invoice, and INVOICE refer to three different files.
