Experimental nuclear and particle physicist. These days I'm teaching, but I've spent a lot of time on nucleon structure in fixed target electron scattering and neutrino oscillations using reactors and beam sources.

comment Which directory MUST exist in / to qualify an OS as Linux
This is, in any case, a feature of the filesystem and not of the OS.

comment Which directory MUST exist in / to qualify an OS as Linux
@strugee You can put those files directly in / and in the bad old days many distributions did. And you can put them elsewhere, though I don't know of any systems that did that.

Or accumulating bad blocks if the drive doesn't automagically compensate.

comment Command-line file reader (like “less”) that can tell the line where the user stopped reading
Similarly to the vim situation open buffers in emacs retain their state unless you close the whole program (or explicitly kill the buffer).

comment Why is the terminal case-sensitive?
"I mean you should be able to execute the command either with "all uppercase" or "all lowercase" characters." Really? Why?

comment Why do Linux people always say to read the manual?
BTW--unless you have a stripped down version for an embedded device you do have the man pages, but you may need to install them with your package manager first (FSM only knows why distributions don't include the man pages in the default pacakage set, but I've seen it).

Other useful hints: read a couple of man pages all the way through and notice the section headings (the See Also section can be immensely useful when you are close, but not quite there). Also learn to use your pager (more or less) as it provides the search interface for the man page (very useful with, say, man bash (which you should never send to the line printer says the voice of bitter experience)).

comment How to create low-overhead file system
@MichaelKjörling "That's an interesting approach that is crazy enough that it just might work." Nothing crazy about it. It used to be very common when saving stuff to tape.

comment Why updating a running Linux system is not problematic?
An open file descriptor has the same power to retain the data on disk as an name for the file in a directory. The original inode will not be deleted as long as there is a hard-link on disk or a open file descriptor. Cache has nothing to do with it. Now, some programs close their file descriptors when they are not using them and that can let the data go away.

comment Search for a string in files recursively in BusyBox 1.0?
Ugh. Neither find nor grep you are left taking mrb's approach.

comment Is there a xterm equivalent that is optimized for use over VNC?
As I recall mosh requires UPD ports, right? Our IT guys won't open those for me. But "outside the box" solutions are always worth hearing.

That, Tim. I know about screen and have tried it in the past, but it never really stuck. If it comes to that I can give it another go.

comment Using more command
And back when "minimum" meant a one- or two-floppy rescue system, of course you used a plain more because it was smaller than less.
