  • Why do "ls" in UNIX and "dir" in DOS have different names?

    - by bizso09
    Why do they have different names for the same command, listing a directory? Surely, they could have talked to each other and agreed on one common name, such as for example cd which is the same for both unix and dos. This decision to have different names has created many headaches for developers and users and also increased incompatibility between the two systems. Did they do it on purpose? Then how come "cd" is the same?

  • How to make it easier when using the vim command in unix?

    - by Mitral
    Recently i try to learn something about the unix. when i try to edit something using the vi command, it is very difficult for me since i have to switch the edit mode and control mode time by time. It is very inconvenient. Is it that i miss something or it is originally like that? Is there anyway to improve that? Thank you :)

  • SmartOS reboots spontaneously

    - by Alex
    I run a SmartOS system on a Hetzner EX4S (Intel Core i7-2600, 32G RAM, 2x3Tb SATA HDD).

We do not have physical or virtual access to the server console - no KVM, no iLO or anything like this. So, the only way to debug is to analyze crash dumps/log files. I am not a SmartOS/Solaris expert so I am not sure how to proceed. Is there any equivalent of Linux netconsole for SmartOS? Can I just redirect the console output to the network port somehow? Maybe I am missing something obvious and crash information is located somewhere else.

  • What does it mean to "have experience with the Unix/Linux command line"? [closed]

    - by Aerovistae
    I'm a new comp sci grad applying to jobs, and this requirement confuses me, especially since the job description (Python back-end developer) says it's the single most important thing ("Everything else we can teach you!") I mean, I know how to use the command line... I know your standard run-of-the-mill stuff like navigating around and manipulating files and permissions and using pipes and running applications, but what are they looking for when they say something like that? I'm aware there's no end to what you can do with the command line, but I was under the impression that after a certain point it's the sort of thing that only benefits server/system administrators.

  • Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

    - by splicer
    I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

  • How to manage reports/files distribution to different destinations in Unix?

    - by mossie
    The reporting tools will generate a huge numbers of reports/files in the file system (a Unix directory). There's a list of destinations (email addresses and shared folders) where a different set of reports/files (can have overlap) are required to be distributed at each destinations. Would like to know if there's a way to efficiently manage this reports delivery using shell scripts so that the maintenance of the list of reports and destinations will not become a mess in future. It's quite an open ended question, the constraint however is that it should work within the boundaries of managing the reports in a Unix FS.

  • Is there a Windows equivalent of Unix 'CPU steal time'?

    - by Steffen Opel
    In order to assess performance monitoring accuracy on virtualization platforms, the CPU steal time has become an increasingly relevant metric - see EC2 monitoring: the case of stolen CPU for an instructive summary in the context of Amazon EC2 and IBM's paper on CPU time accounting for a more in-depth technical explanation (including illustrations) of the concept: Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. Accordingly, it is exposed in most related Unix/Linux monitoring tools nowadays - see e.g. columns %steal or st in sar or top: st -- Steal Time The amount of CPU 'stolen' from this virtual machine by the hypervisor for other tasks (such as running another virtual machine). I've been unable to figure out how to capture the same metric on Windows though, is this possible already? (Ideally for the Windows 2008 Server R2 AMIs on EC2 and via a respective Windows Performance Counters of course.)

  • How to generate an ASCII representation of a Unix file hierarchy?

    - by Jenn D.
    Hi, all. I'm looking for a quick and dirty way to generate some diagrams of some directories that have almost, but not exactly, the same hierarchy, so I can show them around at a meeting and we can decide which flavor we like best. I'm not interested in the "leaf" nodes, just the directories. The catch: I don't want to mess with X. This is a server system I deal with entirely through SSH. So I'm looking for something that will do ASCII layout, maybe with simple pipes-and-hyphens for lines or something. Does anyone know of such a utility? I'm sure I could write something myself, but it's such a fiddly little sort of project, with handling spacing and layout and such; I'd really like to discover that someone's done it for me. Alas, Google doesn't seem to know of such a thing...or if it does, it's hidden beneath heaps of excellent visual explications of the standard general Unix file hierarchy. Thanks!

  • How do you install/configure JBoss on Linux/Unix?

    - by mafro
    I'm currently working on how install and configure multiple (30+) JBoss EAP 5 configurations (both standalone and clusters) for development, test and production at a client's site (running SuSE). I'm not to fancy about the jboss way of storing application/configuration together with system files, so I have tried to split things up (ie moving server config out of the jboss installation directory). I also would like minimize the amount of configuration needed when upgrading/patching jboss - but I'm not done thinking about that... It would be great to hear how you've done and what you think about my approach. This is how my installations look like (for the moment): Standard JBoss EAP install (minus server configs): /opt/jboss/jboss-eap-5.0/jboss-as /opt/jboss/jboss-eap-5.0/jboss-as/bin/ /opt/jboss/jboss-eap-5.0/jboss-as/lib/ /opt/jboss/jboss-eap-5.0/jboss-as/server/ [server configs removed to avoid starting them by mistake] /opt/jboss/jboss-eap-5.0/jboss-as/.../ Application (some jboss folders has been omitted - you'll get the point anyway): /app/<project>/ [$app.dir - application specific base folder] /app/<project>/jboss/ [$jboss.home] /app/<project>/jboss/bin/ -> /opt/jboss/jboss-eap-5.0/jboss-as/bin /app/<project>/jboss/lib/ -> /opt/jboss/jboss-eap-5.0/jboss-as/lib /app/<project>/jboss/server/<cfg>/ [project specific config based on 'production'] /app/<project>/jboss/server/<cfg>/log/ -> /log/<project>/<cfg> /app/<project>/jboss/server/<cfg>/... /app/<project>/jboss/.../ -> /opt/jboss/jboss-eap-5.0/jboss-as/.../ /app/<project>/bin/ [application specific scripts for start/stop etc - wraps jboss supplied scripts] /app/<project>/deploy/ [application deploy folder] /app/<project>/etc/ [application specific config] Questions: How do you install JBoss (on linux/unix systems)? Where do you put JBoss and what modifications do you do? Where do you put your applications and application specific files? Do you share JBoss instances between applications or run one instance/cluster per application? How do you manage configuration changes (i.e. your modifications of jboss standard config)?

  • Unix Permissions: Enable access to files no matter the user?

    - by TK Kocheran
    I've been using Linux for a long time and I still am completely in the dark about how file permissions really work. With that in mind, does anyone have any books or thorough guides I could read to really understand things completely? I've done my fair share of sysadminning, so I know the easy stuff like making directories readable and writable, making files executable, and changing the owner of a file, but on sharing files across users, I'm lost. Here's my main problem. I have a number of machines across which I intend to synchronize my music library. I've been using Unison for a while now and it's a great choice as I can easily run it over SSH on my local network which I just set up. Win-win. Up until this point, I've been synchronizing computers using a 2TB external hard drive. (computer 1 unisons to HD, computer 2 unisons to HD, etc.) This is tedious at best, especially since I encrypted the drive, making it a huge hassle to hook it up to all of my machines and sync it. Anyway, the drive is running ext4 (in TrueCrypt), so it maintains all Unix filesystem info like owners and groups. I just set up a new machine and just Unison'd it to get the music on it, and I realized that now, all of my permissions are fubar. I had to run Unison as root since that was the only way I could get the files to come off of the external drive. Apparently, since I'm using a different user name on this machine than my usual "rfkrocktk" across all machines, this essentially throws a huge wrench in the gears. Here's my use case. This laptop has two effective users, "leandra" and "rfkrocktk". I want to share music between these two users, so I symlinked /home/rfkrocktk/Music to point to /home/leandra/Music. How do I (a) allow both users access to read/write/delete files in this folder, and (b) keep everything nicely in sync without messing up file ownership?

  • What parts of this book are outdated? "Design of the UNIX Operating System" by Maurice Bach, 1986

    - by blee
    I learned programming on the job via high-level languages. I'm trying to gain a better understanding of the lower-level workings of computing and picked up "Design of the UNIX Operating System" by Maurice Bach. What do I need to know in terms of which topics in this book may not be relevant to understanding Linux nuts and bolts? Is there a newer book or Linux-specific book that I should read instead? I really like the clarity of this particular book, though.

  • UNIX find for finding file names NOT ending in specific extensions?

    - by Cristi Diaconescu
    Is there a simple way to recursively find all files in a directory hierarchy, that do not end in a list of extensions? E.g. all files that are not *.dll or *.exe UNIX/GNU find, powerful as it is, doesn't seem to have an exclude mode (or I'm missing it), and I've always found it hard to use regular expressions to find things that don't match a particular expression. I'm in a Windows environment (using the GnuWin32 port of most GNU tools), so I'm equally open for Windows-only solutions.
