I am a scripting language connoisseur, regular expression aficionado, network geek, general lover of Linux and a frequent contributor to open source software. I transitioned to programming from other work because I was too busy automating my own work environment to actually do the other work. I have a hobby interest in cartography. For more see my personal site. Most importantly, my life is defined by the grace of God given to men through Jesus Christ. It is my ambition that everything I do would reflect His glory and point people towards Him.

This should be possible with a compositing window manager, but you might have to cobble together some pieces to make it happen.

comment How to tell which file is original if hard link is created
@hauke The issue here is not having to explain to you the technical situation --I have no concerns that you don't have a general grasp of things-- the issue is that you skipped explaining the technical situation to the visitors here on an issue they are likely confused on. If they got here by searching (or just read the title) they probably need the nature of hard links explained.

comment How to tell which file is original if hard link is created
-1 because, although the info about how the directory changes in some file systems when updating the tables, this answer fails to clear up the miss-understanding present in the question that "original file" is not a property in the case of multiple hardlinks to a single inode. In that sense while is in anecdotally interesting it is not what most people landing on this question should learn about the fundamental concept of hardlinks. This issue is not a lack of a "direct clean way to do it", the issue is that there is no "it" in the first place.

comment IO redirection and the head command
@voithos Yes commands in a pipline and all the input/output channels involved are started in reverse order so the pipeline is ready to receive data when the first one starts giving it. I suspect your test is flawed because you probably used too small a chunk of data and it got the whole thing cached in a read buffer before you needed it. The tee program will truncate your files, it is not setup to double buffer them.

comment IO redirection and the head command
@voithos To my knowledge tee opens and truncates the file it is writing to when it is instantiated just like everything else so it does not solve the main issue here of the race condition on reading the file contents before you truncate it with the write.

@C.R. Try it and see. If the previous one has not released the port a now one cannot open it for listening and will give you an appropriate error.

comment What is the easiest way to boot Linux from a USB drive on Intel Mac?
This is just flat wrong and your comments make it worse. Please defer to the people that have epertise. Not all computers have BIOS's (I have some that don't even have EFI) and this "solution" is completely irrelevant to this question. Do your research, know what you are talking about, check that it works, then explain it to others.

@slm Thanks. I'm open to suggestions on how to improve it. I'm a little surprised at the reaction myself. Maybe it's my dig at Arch-' "The Way"? I'm not a fanboy here, I'm just trying to use the tools the way they were intended to be used.

comment How can I start Apache on Arch Linux w/systemd using passphrase protected SSL keys?
@bersch And before you throw the book at me about virtual machines only being as secure as their host etc etc, I am not worried about the current admins or running environment so much as the backup system that ships snapshots offsite. I have the data in encrypted file systems so that is safe enough from, say, a tape getting into public hands but the root FS of the VM, per policy, needs to be a normal file system and I don't want to leave unlocked private keys that would work to serve things as being signed by me personally lying around on on a FS that might someday be other other admins.

@bersch Your opinion an security practices does not invalidate my question about Arch's implementation of systemd/apache. You have a point about system security, but some certs do more than secure data over the wire, they also verify the identity of the provider. I want to be able to run an SSL service that is signed with my personal credentials on a box in a virtual machine in a shared environment where another admin could snapshot my machine and extract the file system. I realize it won't make the service and data the cert protects any more secure but it will prevent my ID from exploitation.
