comment Why “ grep * ” not working?
@tripleee: I've seen this "award" tossed around with glee on sites like SO. I don't think it is appropriate. We're not talking about production code here; the cat in this example is a generic stand-in for "when I'm grepping some arbitrary standard input". An answer is easier to comprehend when it doesn't turn an abstract example into something else entirely just for the sake of showing off your leet skills of avoiding "unnecessary" uses of cat -- but sticks with the original code and shows the few twists that are actually related to the core of the question.

comment Bash change user info (like usermod) but without root privileges
It's quite logical if you think about it. Only the admin (root) decides who may log in, usually after asserting their identity. So allowing people to change how they appear on the system - i.e. "disguising" themselves - would be defeating the purpose of access control. The way to change your fullname is to talk to your system administrator.

Changing user information requires access to /etc/passwd, which is owned by root and not writeable by others. No dice. Being root or having appropriate sudo permissions is the only way (and I seriously doubt the latter will be granted to some self-written GUI app by any security-aware admin).

comment Invoking vi through find | xargs breaks my terminal. Why?
Huh... the trick there is the + (instead of "the usual" \;) to get all the found files into one Vim session -- an option I keep forgetting about. You are right, of course, and +1 for that. I use vim $(find ...) simply out of habit. However, I was actually asking for why the pipe operation screws up the terminal, and grawity nailed that with his explanation.

comment Installing Linux *to* a NFS mount
As I said above, pretty much obvious once I got my mind out of the tight little corner of being hell-bent on using the NFS mount directly. Thanks.

@ekaj: So painfully obvious that I stared at my monitor for a minute trying to figure out why I had been so blind. Especially since I have an empty USB drive sitting right next to me on the desk... turn that into an answer and you get the checkmark.

comment Systems sharing /home via NFS freezing (on ICY BOX IB-NAS5220)
@KyleJones: Still no success at reliably reproducing the symptoms. But by now I can say that it even freezes user input at the console (i.e., system doesn't react to keyboard strokes), which makes me suspect a kernel issue. And no, it's not energy savings mode - it doesn't only happen at the first few accesses, but intermittently. I scrapped the "shared home" setup, and hope it gets better when the mount is only a subdirectory of $HOME.
