comment Saving time while compiling Kernel
@7_R3X: Perhaps build in advance and delete half a dozen .ko files and the arch outputs. Then the next build will have to recreate only those.

comment Saving time while compiling Kernel
Rebuilding a module doesn't require rebuilding any of the kernel. Once it's compiled with the right parent and bus drivers once, the module code can be rebuilt as many times as needed, while still using the exact same kernel binary. So get yourself a kernel build tree, but don't do the build live.

comment What is this dd if=/dev/zero of=/dev/sda do
@shelvacu: It's destructive. If destructive commands were posted without an explanation of what it does, it's malicious. If they were accompanied by an explanation, why is OP asking about it here?

@MichaelHampton: s/malicious/destructive/ While posting destructive code is not malicious per se, posting it without a clear warning that it can destroy data IS.

comment Is there any reason to have a shebang pointing at /bin/sh rather than /bin/bash?
@BinaryZebra: "A shell" will be available, yes. But bash is not necessarily that shell (in particular most SOHO routers use ash which is provided with busybox), and I tend to think zwol is right that perl is more commonly available than bash.

comment Triggering Linux shutdown on power failure
@JeffSchaller: At the moment, I'm willing to trust the programmed powerfail actions to do the right thing (pf::powerfail:shutdown -fh or powerfail::powerfail:/etc/rc.powerfail on sysvinit, sigpwr.target for systemd) and reconfigure those later if needed. Right now I'm focused on making "it learns of power failure" happen when the edge comes in on that GPIO.

comment Why does Vim indent pasted code incorrectly?
It may be worth discussing the interaction with set mouse, which can automatically enter and leave paste mode when pasting with mouse click.

How are you triggering the paste? With the mouse?

comment Is USB-to-USB data transfer between two Linux OSes possible?
@Lekensteyn: It's not uncommon for tablets, and some tablets really are full PCs. There's probably high correlation between host-only USB ports and full PC, however.

comment How can I quickly find the 20 most recently modified files on Mac OS X (instead of using Python)?
No, definitely not. StackOverflow is for questions about programming; not usage of the system. SuperUser would be more appropriate. (Writing the python script might involve a StackOverflow question, but your overall problem would not)

Try to trim the amount of data being piped to poor overworked sort.

Probably because this question is not unique to professional server administration; an end user might ask the same thing.

Pass -mtime or -mmin to find to reduce the number of entries the Python script has to parse and sort.
