  • How to run Windows 7 Explorer shell with Administrator Privileges by default

    - by Barry Kelly
    The Windows 7 shell (Explorer) can be made to run with Administrator privileges by this manual process: Kill Explorer shell by holding down Shift+Ctrl, right-clicking the Shut down button in the Start Menu, and selecting Exit Explorer Start Task Manager with Ctrl+Shift+Esc Elevate Task Manager privileges by going to Processes tab and selecting Show processes from all users Then start up a new instance of the shell by File | Run in Task Manager, typing in explorer, and selecting the Create this task with administrative privileges. After following the above process, the Windows shell will be running with administrative privileges, and any programs it launches will also have administrative privileges. This makes performing tasks that require the privilege far easier, particularly for command-line applications, which usually fail silently or with an Access denied. message rather than giving an opportunity to use UAC to elevate the process's privileges. What I'm interested in, though, is creating an account which uses a privileged shell by default, rather than having to follow this laborious process every time. How can it be done?

  • How can I change shell in Ubuntu?

    - by Sanoj
    I have a Ubuntu Server VPS and I want to use /bin/bash/ as my shell. How can I change my shell? I have root access but I don't work as root. So dash is my default shell now. I have read How do I make Bash my default shell on Ubuntu? and chsh seams to be the preferred way to go. But when I type chsh /bin/bash I get this message: chsh: unknown user /bin/bash And if I just type /bin/bash the Bash shell seams to work fine. How to change it?

  • Add "not" to if statement in shell script

    - by John Crawford
    I have the following script that should exist if the user does not exist. #check if user currently exists on system if id $User > /dev/null 2>&1 then #user exists no need to exit program echo "blah blah, what a waste of space" else echo "This user does NOT exists. Please create that user before using this script.\n" exit fi My problem is that I would ideally like to place a "not" if that first if statement so that I can trim down my if, else statement. Ideally I would like something like this: if !(id $User > /dev/null 2>&1) then echo "This user does NOT exists. Please create that user before using this script.\n" exit fi

  • What does /dev/null mean in the shell?

    - by rishiag
    I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

  • Why most use Cygwin and not Uwin?

    - by user287424
    Most academic researchers I know target just *nix, and rely on Cygwin to make their applications available on Windows. I have tried many of these projects and always found them too unstable for serious use when running on Cygwin. Uwin looks like a promising alternative to Cygwin. I haven't tried it yet, but I found several comments that it is faster and more stable. However, I haven't seen any use of Uwin to support running *nix apps on Windows. What are the social and/or technical reasons behind Uwin's lack of popularity?

  • How to do parrallel processing in Unix Shell script?

    - by Bikram Agarwal
    I have a shell script that transfers a build.xml file to a remote unix machine (devrsp02) and executes the ANT task wldeploy on that machine (devrsp02). Now, this wldeploy task takes around 15 minutes to complete and while this is running, the last line at the unix console is - "task {some digit} initialized". Once this task is complete, we get a "task Completed" msg and the next task in the script is executed only after that. But sometimes, there might be a problem with the weblogic domain and the deployment might be failing internally, with no effect on the status of the wldeploy task. The unix console will still be stuck at "task {some digit} initialized". The error of the deployment will be getting logged in a file called output.a So, what I want now is - Start a time counter before running wldeploy. If the wldeploy runs for more than 15 minutes, the following command should be run - tail -f output.a ## without terminating the wldeploy or cat output.a ## after terminating the wldeploy forcefully Point to be noted here is - I can't run the wldeploy task in background, as in that case the user won't get to know when the task is complete, which is crucial for this script. Could you please suggest anything to achieve this?

  • Get more space for redis in unix server

    - by DevTraveler
    In our app we have only windows servers beside the cases we use redis queues. This case , we use unix server created by amazon. As you can see we do not have a lot of space available and we want to make sure redis has enough space to work without getting stuck. I am little bit new in unix and after reading some data about the unix file system i still was not fully sure how can i give the redis drive (it is in the home directory) more space. I see the mnt that has a lot of space but read it is temporary for cd-rom and network drives. Can you help me figure out how to get more space to my redis ? If it is possible i prefer not to re-install the redis server. Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 6.7G 880M 89% / udev 7.4G 4.0K 7.4G 1% /dev tmpfs 3.0G 152K 3.0G 1% /run none 5.0M 0 5.0M 0% /run/lock none 7.4G 0 7.4G 0% /run/shm /dev/xvdb 414G 30G 364G 8% /mnt Thanks.

  • Regarding Unix Move Command

    - by user38993
    I need to write an Unix Shell Script tran.sh that moves the csv input files from /exp/files folder to /exp/ready directory. The csv input files are written to /exp/files folder by an FTP server whose behavior I cannot trivially change. In tran.sh shell script I need to ensure before doing a move of that csv input file from /exp/files directory no longer any other process is writing to the file. How can I do it.

  • Unix and FreeBSD

    - by Alex Farber
    My final goal is to write the program which can run on the Unix OS. I know that there are many Unix versions, and don't know exactly for now which one I need to support. I cannot install any Unix OS right now. The only thing I can do is to use free OS which is close to Unix as much as possible. Is FreeBSD a good choice for this? I know that there is also OpenBSD, possibly something else.

  • What are the options for setting up a UNIX environment to learn C using Kernighan and Richie's The C Programming Language?

    - by ssbrewster
    I'm a novice programmer and have been experimenting with Javascript, jQuery and PHP but felt I wasn't getting a real depth of understanding of what I was doing. So, after reading Joel Spolsky's response to a question on this site (which I can't find now!), I took it back to basics and read Charles Petzold's 'Code' and am about to move onto Kernighan and Richie's The C Programming Language. I want to learn this in a UNIX environment but only have access to a Windows system. I have Ubuntu 12.04 running on a virtualised machine via VMWare Player, and done some coding in the terminal. Is using a Linux distro the only option for programming in a UNIX environment on Windows? And what are the next steps to start programming in C in UNIX and where do I get a compiler from?

  • trap "" HUP v.s Nohup ? How can I run a portion of shell script in nohub mode?

    - by Alex
    I want to run a shell script over the weekend, but I wanna make sure if the terminal loses the connection, my script won't be terminated. I use nohup for the whole script invokation, but I also want to execute some portion of my shell script in a way that if someone closes my terminal, my script runs on the background still. Here is a simple example : #!/bin/bash echo "Start the trap" trap " " HUP echo "Sleeping for 60 Seconds" sleep 60 echo "I just woke up!" Please suggest what I should do ? The trap " " HUP seems like not working when I close my terminal tab.

  • What is the most robust way of determining the current codepage from a shell script?

    - by rewbs
    Hi all, I'd like to determine the environment's current codepage at runtime from a Unix shell script. What's the most reliable way of doing this? I'm looking into parsing environment variable $LC_ALL, but it isn't always set to a useful value, and its format seems to vary (can be <locale, or <locale.<code page, or <locale.<code page@<modifier etc...). Is there a better way? I'm essentially after a shell equivalent of what I'd get if I called nl_langinfo(CODESET) from C.

  • How to trigger cross-platform jobs between Windows and Unix

    - by andyb
    I have an application which has components on Windows and Unix. I need to run overnight jobs which initiate tasks/jobs on both environment. These need to be sequenced so I cannot simple use Cron / Task Scheduler. For each job, there will be a controlling script either on Windows or Unix, but this script will need to initiate jobs on the other environment and detect when they are complete and a success/failure code. In the past I have achieved this using 'flag files' on a samba share. This worked but required 'polling' behaviour on the receiving end which I do not consider optimal. I would prefer not to have to embed user credentials in script if possible.

  • C Differences on windows and Unix OS

    - by zapping
    Is there any difference in C that is written in Windows and Unix. I teach C as well as C++ but some of my students have come back saying some of the sample programs does not run for them in Unix. Unix is alien for me. Unfortunately no experience with it whatsoever. All i know is to spell it. If there are any differences then i should be advising our department to invest on systems for Unix as currently there are no Unix systems in our lab. I do not want my students to feel that they have been denied or kept aloof from something.

  • SCO UNIX problem: "Cannot create /var/adm/utmp or /var/adm/utmpx"

    - by Maktouch
    Hey everyone, I have an old server that doesn't boot. I don't know the version of unix installed, but I see SCO UNIX. It stops with that error: UX:init: ERROR: Cannot create /var/adm/utmp or /var/adm/utmpx UX:init: ERROR: failed write of utmpx entry: " " UX:init: ERROR: failed write of utmpx entry: " " UX:init: INFO: SINGLE USER MODE After that message, it just stops. I cannot write or press anything. Even CTRL + ALT + DEL does not work. I cannot get into the system. I have tried booting with a DamnSmallLinux LiveCD but it does not recognize the file system on HDA. Is there a way to either log in as root or bypass this error? Thanks.

  • SCO Unix - finding and pulling data

    - by lxlxlxl
    We recently acquired a company that was running a legacy application on a SCO Unix box. I can tell that the app is running off of http, but its reporting and data export functions are limited and I'd like to find a master db or data source on the box that maybe I can migrate into something more useful. Any ideas how I could possibly find that? Would there be something in apache or startup scripts that might point to a master db? do Unix applications have standard data source locations? I'm not sure if I'm wording this right so apologies in advance.

  • Any book that covers internals of recent versions of Unix OS

    - by claws
    This summer I'm getting into UNIX (mostly *BSD) development. I've graduate level knowledge about operating systems. I can also understand the code & read from here and there but the thing is I want to make most of my time. Reading books are best for this. From my search I found that these two books The Design and Implementation of the 4.4 BSD Operating System (1996) "Unix Internals: The New Frontiers" by Uresh Vahalia (1996) (See here for 2nd edition) are like established books on UNIX OS internals. But the thing is these books are pretty much outdated. So, Is there any recent books that covers internals of recent Unix OS? How about books on other Unix operating systems? They seem to be recent than above books but how close are they to OpenBSD/FreeBSD? Solaris 10 and OpenSolaris Kernel Architecture, 2 edition (July 20, 2006) HP-UX 11i Internals (February 1, 2004) I really don't prefer HP-UX as its not open source.
