comment POSIX head and tail not feature equivalent
@StephaneChazelas, GNU head -n -1 needs also one line of storage (or two depending what you are really counting). And doesn't fail here.

comment End of lines problem in emacs when editing markdown texts via It's All Text
I'm far from sure it is an emacs problem and not an "It's All Text" one. Do you reproduce with a simple text file? If yes, does customizing require-final-newline solve your problem?

comment Why doesn't tar ask before overwriting existing files?
@mattdm, git handles trees, RCS handles files. For config files, this an advantage of RCS (in most contexts, it is a source of problems).

comment What is the concept of Drives in Unix Systems?
I'm far from convinced that there is a relationship between fixed disks and the notion of mounting. The notion of a single hierarchical name space is quite unique to Unix and its descendant (and perhaps Multics which ISTR introduced the directory hierarchy, I don't know if it was unique). Other OSes I know (TOPS-10, TOPS-20, VMS) use structured names with a device designator, even when they have a notion of directory hierarchy. And Unix uses names in the directory hierarchy to refer to mountable devices (tapes and mountable hard disks).

@JamesLitewski. you got the things in the reverse order. Undex Unix, the GUI is mostly an application layer which run over the OS. Any variant will easily provide you with a command line interface and just that (with the potential exception of MacOS about which I know very little).

Well, that's a simplified version of the history. See levenez.com/unix for a more complete one.

comment Is an SSH connection faster if I lower the RSA key size?
The problem with X is that it is a protocol which doesn't support very well high latency -- and applications are even worse that needed by the protocol in such context. You may want to use an X protocol compressors (I've never done that, I remember seeing some). Or switch to something like VNC.

Note also that some commands such as cd must be a shell builtin to work effectively.
