Fairly often, according to coworkers. ExcessBLarg! posted:Honestly the Rob Landley explanation makes the most sense. Rob Landley was mostly joking, there. I'm sort of surprised at how often that mail is quoted as truth. ExcessBLarg! posted:At least in "modern" usage, /bin and /usr/bin are binaries used by non-privileged users are stored, whereas /sbin and /usr/sbin are where binaries intended for use by the superuser (root) are stored. This is why /bin and /usr/bin are in $PATH for normal users, and /sbin and /usr/sbin are only in $PATH for root. But /sbin has plenty of binaries that are able to be used by non-superusers, and /bin has plenty of superuser-only binaries. Of course the "statically linked binary" distinction doesn't make sense anymore; most Linux distributions are based around GNU coreutils which links a bunch of the coreutils anyway. It comes from BSD, which is where shared libraries started.

But they're generally thought to be programs that regular users shouldn't need to use--which is why they're partitioned, but not permissioned off entirely.

Thermopyle posted:So, basically...the Linux file system is a joke? Depending on your bias, all file hierarchies are jokes. It depends what kind of humour you have. In my experience Linux started out with a very BSD-based hierarchy and moved over to the SysV/Solaris variant over time. Now it seems whenever a distro gets enough clout over the standards process, it introduces its own quirks. I've been using Debian for over a decade and I think /opt is a stupid idea and usually symlink it as quickly as possible. /usr/share has become a horrible Byzantine maze and /var is less and less variable. I had to resize the root partition recently because I was running out of space at over 340MB. /lib is taking up half of that now. ewe2 fucked around with this message at 19:33 on Sep 6, 2012 |

A file hierarchy is a method of organizing the system!

Can some one school me on using rdiff-backup? To do a local backup I am trying: rdiff-backup --exclude-special-files --include-globbing-filelist /home/patrick/Junk/rdiff-selection / /run/media/patrick/Bucket/rdiff-backup/ code:Also, what is the proper way to run something like this? Some of the stuff in /etc can only be read as root; should I just run it as root? A side effect is that it seems to make all the backup directories/files root:root 0600 which is pretty annoying if I want to browse them in nautilus. The backup disk is encrypted, as rdiff-backup doesn't seem to do that.

Err, something is suddenly taking up all the space on my home partition. I was playing Dota 2 using Wine and the game crashed, I switched display (Steam runs in it's own X display) and killed it. Now I think some cache or something wasn't cleared because of how it was killed. The partition is now 100% in use, which is ridiculous as it was nowhere near full before. How can I find the files causing this and delete them? VVV - Thank you. I used Baobab. I'm on XFCE and it didn't require any dependencies whatsoever so it can't require that much of GNOME. It was really helpful and I sorted the problem. For some reason the Team Fortress 2 folder had exploded, which is odd because I've never even launched that game on this Wine prefix.

baobab is the Disk Usage Utility for GNOME (I'm not sure how much of GNOME it requires - it might require GVFS/udisks). There's KDirState for KDE.

I am feeling a bit smug because I have virtualization going with a Fedora 18 host and a bridged network. I almost had bridging working with networkmanager, but I think it isn't quite ready for primetime. Does anyone know the proper way to share a directory to guests? libvirt has the Filesystem passthrough concept which I cannot figure out. There are various modes (passthrough, squash, mapped), different drivers, and I am not clear how to specify the target path. Redhat/fedora docs and google are not helping me out here  I would like the guest to be able to access a directory on the host and it would be nice (and more efficient?) if I didn't have to set up any sort of file sharing. edit: Doh, it just hit me that filesystem passthrough probably is for exposing a host filesystem to a guest, not for something simple like a folder. I feel a bit dumb right now. other people fucked around with this message at 22:57 on Sep 19, 2012 |

I almost had bridging working with networkmanager, but I think it isn't quite ready for primetime. If they're linux guests, NFS is the "easy" way to do it. That is to say, easy for a simple setup, but you can make it pretty complicated and unwieldy depending on your requirements. Also, I've got ESXi running with CentOS, Fedora, Windows 8, OS X Mountain Lion Server, and 3 virtual IPs (public; the other is my home network, which my other adapter is connected to).  With kickstarted CentOS installs completely unattended other than setting the hostname, running off of a locally mirrored CentOS repo, and automated puppet installation. All done during my spare time.

I've recently setup a DAAP server on my server so that I can stream my music to music players through a VPN. I would really like to know the bandwidth that I'm using since our house is on a monthly cap. What is the best solution for me to record usage information to a log file? I know the IP address from which I will be streaming the data (as well as the port number). Any suggestions? Edit: Basically I want the output of ifstat but just for traffic to a particular IP/host and port. Modern Pragmatist fucked around with this message at 16:48 on Sep 21, 2012 |

I hope this is the right place to ask this. I am a total noob to this sub-forum and to Linux. I wanted to fool around with Linux for the hell of it and to see if I could teach myself something so I installed Ubuntu 12.04 on a usb drive to use with my old netbook and it is slow as molasses. I am working with a Dell Mini 10 with the following... 992.1 MiB memory intel atom cpu n270 @ 1.60GHz x 2 32-bit OS Which should meet the minimum requirements, right? So what gives? I don't even know where to start. Thanks for any help.

It's probably slow because #1 a netbook isn't very powerful and #2 Ubuntu has a graphically intense interface. I'd try lubuntu, xubuntu, or the LXDE or XCFE spins of Fedora. There's also other distributions like SuSE.

I'm trying to run a program to sync my Firefox profile to RAM at startup and shutdown on Ubuntu 12.04. I have the startup part working, with ~/.config/autostart (a GNOME thing?) and I was wondering if there's anything similar to run programs at logout or shutdown at the user level (as in, without /etc/init.d.) I tried to use /etc/init.d to delegate to a file in $HOME, but I couldn't make it work correctly. I'm not sure if the issue is permissions, environment variables or what.

No. Shutdown is supposed to not do anything special other than shutdown (what if your power cuts out) There's already a number of Firefox extensions that save session state; maybe you could use parts from those?
