• Change YYYY-MM-DD to YYYYMMDD everywhere in file

  - by richardh

  I can't just delete all of the hyphens, because elsewhere they are used as minus signs. I can find these dates with [0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\} but I can't figure out how to keep those three different digit wildcards in memory. My attempts end up replacing the dates with the search string (e.g., :%s/[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}/[0-9]\{4\}[0-9]\{2\}[0-9]\{2\}/g). Any ideas? If there's a command line solution, I'd love to learn that, too. Thanks!

• Close all Mac Terminal windows, but the one running a script

  - by Greg Brown

  I am trying to create a shell script that runs a python simulation programing in 4 terminal windows. I have the script that launches the program four times in four separate terminal windows(total of 5 windows, 4 for the python programs, and one to control the other terminal windows). I want to now create a script that I can run in the control terminal window that closes and kills the programs of the other four terminal windows, but still have the control one open. What I have so far is something like this #!/bin/sh osascript -e 'tell app "Terminal" do script "killall python" end tell' osascript -e 'tell app "Terminal" to quit' osascript -e 'tell app "Terminal" to open' The problem is that the last line doesn't work because it closes all the windows including the one the script is executing in. I am not really familiar with shell or apple script so any help would be welcomed. I posted on Stack, but I think this might be a better place for an automation type question. Thanks

• Problems starting MySQL on Mac OS X

  - by Jon

  I am not able to start MySQL server on Mac OS X 10.4.11. MySQL was installed using Macports. MySQL was running fine until it suddenly died without any obvious reason. When running "mysql", I get the error message: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2) If I try to start MySQL manually, I get the following error message: sudo /opt/local/share/mysql5/mysql/mysql.server start Starting MySQL/opt/local/share/mysql5/mysql/mysql.server: line 159: kill: (636) - No such process ERROR! In /etc/mysql/my.cnf I have: socket = __PREFIX/var/run/mysqld/mysqld.sock But the path "opt/local/var/run/mysqld/" does not exist on my system. I tried to change the socket path to "__PREFIX/var/run/mysql5/ mysqld.sock" (which is where the socket is located). Unfortunately, this did not help either. Owner and Permissions for /opt/local/var/run/mysql5/ are correctly set. Any suggestions on how to start MySQL again? Thanks for your advice.

• Errors reported by "powercfg -energy"

  - by Tim

  Running "powercfg -energy" under Windows 7 command line, I received a report with following three errors: System Availability Requests:Away Mode Request The program has made a request to enable Away Mode. Requesting Process \Device\HarddiskVolume2\Program Files\Windows Media Player\wmpnetwk.exe CPU Utilization:Processor utilization is high The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization. Average Utilization (%) 49.25 Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer. I was wondering for the first error, what does "enable away mode" mean? for the second, what utilization percentage of CPU is reasonable? for the third, what is "PCI Express Active-State Power Management (ASPM)"? How I can correct the three errors? Thanks and regards!

• I'd like to rebuild my web server without web management software; what knowledge, skills, and tools will I require? [closed]

  - by Joe Zeng

  I've been using Webmin for my web server that runs my personal website and a host of other websites for a while now, and I feel like I should be able to manage my web server more directly, because I haven't even touched the Webmin for the past year or so and I feel like maybe it has too much functionality that I have to click through the next time I want to access it or create a new subdomain or database on my site. I want to try something lighter and more wholly manageable, now that I'm more comfortable with using ssh and command-line tools. I've decided that I'm going to try using Django as a framework, but obviously that's only part of the picture. What sort of knowledge will I require?

• Macports irssi & perl5 installation issues

  - by Dmitri DB

  Long time reader, first time poster. Big, appreciative thanks for everyone's collective questioning and answering here and at stackoverflow, it's helped me quite a lot over the time I've been learning answers through these sites! Apologies in advance if I didn't search hard enough on posts already up on this site to find out what I could do about this issue, but I thought I'd just reach out for the sake of trying at least once. I've experienced this issue while starting up my macports-installed version of irssi: 13:25 -!- Irssi: Error in script dispatch: 13:25 Can't locate lib.pm in @INC (@INC contains: /opt/local/lib/perl5/site_perl/5.12.4/darwin-multi-2level /opt/local/lib/perl5/site_perl/5.12.4 /opt/local/lib/perl5/vendor_perl/5.12.4/darwin-multi-2level /opt/local/lib/perl5/vendor_perl/5.12.4 /opt/local/lib/perl5/5.12.4/darwin-multi-2level /opt/local/lib/perl5/5.12.4 /opt/local/lib/perl5/site_perl/5.12.3/darwin-multi-2level /opt/local/lib/perl5/site_perl/5.12.3 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl .) at (eval 18) line 1. 13:25 BEGIN failed--compilation aborted at (eval 18) line 1. 13:25 Huh, strange.

I'm not really a perl user beyond enjoying it for massive directory-recursive find/replace operations within text files, so I haven't much of an idea what the permissions here are supposed to look like, and I'm not really sure how to go about determining how macports has gone and installed perl this way when it's otherwise worked without failure for years now. Does anyone have any recommendations for the sanest path towards rectifying this issue? Also, is there any interesting reason as to why the macports default for the perl5 port installs 5.12.4, and not 5.16.0, which has to be explicitly installed via the perl5.16 port? Thanks again!

• Running Windows 8 Consumer Preview to Pro

  - by elvispt

  Currently I have Windows 8 Consumer Preview installed I tried running the Windows 8 Upgrade Assistant, and it tells me, after checking for compatibility, that I can buy Windows 8 Pro for 29.99euros. Will I have any issues with this? Will I be able to perform a clean install from the downloaded file? I heard that I could not get Windows 8 Pro at this price, only If I had Windows 7 installed. The bottom line is, what kind of issues can I expect if I decide to go down this path? Will it ask me later for a key of Windows 7 to validate? Thanks.

• How can I edit local security policy from a batch file?

  - by Stephen Jennings

  I am trying to write a utility as a batch file that, among other things, adds a user to the "Deny logon locally" local security policy. This batch file will be used on hundreds of independent computers (not on a domain and aren't even on the same network). I assumed one of the following were my options, but perhaps there's one I haven't thought of. A command line utility similar to net.exe which can modify local security policy. A VBScript sample to do the same. Write my own using some WMI or Win32 calls. I'd rather not do this one if I don't have to.

• Redirecting X output

  - by Adam Matan

  Hi, I have a small program that checks some elements of a web service. The program shows graphics output and displays commmand-line results as well. I have been trying to automate this program to run periodically on a server in my office. Problem is, It only works when I have X enabled - either directly on the server, or via ssh -X. Following Google, I have tried Xvfb, which gave me quite cryptic error message: Xvfb :1 -screen 0 1600x1200x32 Fatal server error: Server is already active for display 1 If this server is no longer running, remove /tmp/.X1-lock and start again. Any ideas how to run it? I'm actually looking for the X equivalent of &>/dev/null... Thanks in advance, Adam

• Wikipedia Images don't show up in browsers

  - by mantra

  It's a weird issue with wikipedia which had left me frustrated. When I go to wikipedia, with different browsers ( IE8, Chrome3, Opera10 ) no image in the site will show up. Even right-clicking the image to ( show, save, open in new tab/window ) will return nothing except when open in new tab/window I'll get a black horizontal line across the page. All my browsing across the web goes flawlessly, and every image in every site show up normally except in the wikipedia site. I have win7 ultimate with all updates.

• Using windowmaker with quartz-wm in proxy mode on Snow Leopard

  - by Graham Lee

  I can modify my .xinitrc file to exec /opt/local/bin/wmaker, and get WindowMaker 0.90.2 as my window manager in X11.app. I'd like to use quartz-wm not as a window manager, but to provide the pasteboard integration with Aqua using the --only-proxy flag (see the man page). If I add the following line to .xinitrc: exec /usr/bin/quartz-wm --only-proxy & then WindowMaker never starts, complaining that there's already a window manager running. Is it possible to get the two to play nicely together, or is proxy feature part of the Xquartz server now? It seems that the Xquartz manpage has a number of pasteboard-to-clipboard synchronisation settings, but it's not clear whether quartz-wm needs to be running for those to work.

  - by choise

  Hi, after a other mac or macbook is connected with a mini display port to a new generation imac you can switch between the imac and the other connected mac pressing cmd+F2(brightness up) using the keyboard of the imac. i connect my macbook to my imac, switch to the macbook and connect the bluetooth keyboard and mouse of my imac to my macbook. after that i'm not able to switch back to my imac, because the keyboard is used on my macbook. i have a second mouse connected to my imac, so i'd would be cool to switch views and control my imac with my second mouse. is it possible to send the shortcut cmd+F2 to my imac from my macbook? via command line or something? using apple script? all ideas are welcome, thanks!

• ajaxplorer: open_basedir restriction in effect

  - by mrzasa

  I'm trying to install ajaxplorer at a shared hosting in my home folder. When I navigate to the main page, I get an error: is_writable(): open_basedir restriction in effect. File(/var/lib/php5) is not within the allowed path(s): (/var/www//username/:/usr/sbin/sendmail:/usr/share/php :/home/www/appname::/usr/share/pear:/dev/urandom) What might be the cause? How could I fix it? There is php 5.3.3 installed, apache 2.2.16. I use ajaxplorer 4.0.4. EDIT: The problem is caused by this code part: $tmpDir = session_save_path(); $this-testedParams["Session Save Path"] = $tmpDir; if($tmpDir != ""){ $this-testedParams["Session Save Path Writeable"] = is_writable($tmpDir); Error appears in the last line, but I enclosed the context.

• Installing raid controller forces reinstall of Windows Server 2008

  - by Tyler

  So, I've tried two different RAID controllers that have external SATA connections on my Server 2008 machine. I can install the hardware, boot into Windows, install the drivers and reboot again. No problems. However, as soon as I try to use eSATA-connected drives and reboot something happens to the Windows install and I can no longer boot into Windows. I tried repairing from the command line, and the end result is that repair console tells me I have 0 Windows installations (?). I end up having no choice but to reinstall Windows to get back on track. I must be doing something fundamentally wrong here, but I don't know what :(

• Bootstrap a debian build environment and build source packages with no root privileges

  - by Erwan Queffélec

  On debian squeeze, I am trying to do the following : fetch sources package from the wheezy source repository bootstrap a squeeze chroot for several architectures build the packages for several architectures (i386, amd64 + all and any) I want both the fetching, bootstrapping and build operation to be scriptable, repeatable, and run as a normal user. For the environment setup, I want to make as little use of the root account as possible (install the necessary dependencies, and maybe some visudo stuff). If possible I would like to avoid using a VM (pbuilder with user mode linux) So far I have tried several things with pbuilder (require root), debootstrap (require root) with little success. Here is an example script of what I want to do (does not work): #/bin/bash set -e set -x this=`readlink -f $0` this_dir=`dirname $this` archs='i386 amd64 any all' pushd $this_dir/src # I actually want the following line to work with a repo that # is not in /etc/apt/sources.list but that is another question apt-get source cyrus-imapd-2.4 popd for arch in $archs do build_dir=$this_dir/build/$arch/ pbuilder --create --configfile $build_dir/pbuilderrc --buildresult $build_dir/ pbuilder --build --configfile $build_dir/pbuilderrc --buildresult \ $build_dir/ $this_dir/src/*.dsc # of course I want to use the .dput.cf in /home/myuser/ # and not in /root/ dput $build_dir/$arch/*.changes done

• requests are taken to the wrong directory

  - by gidireich

  Hi, I use xampp on windows 7 64, to test locally my php web application I use virtual hosts to have access to my code from different domain names. Now, I created a new version of the code and want to access both versions using different domain names. I added a new virtual host newversion.mysite.local to httpd-vhosts.conf and directed it to the directory of the new version. Also updated the windows hosts file with the line 127.0.0.4 newversion.mysite.local A strange thing happens: when browsing to newversion.mysite.local I'm being taken to the old version, which is located at a different location. How the hell this happens? Please help me with ideas Thank you Gidi

• Components needed for a VPN

  - by Anriëtte Combrink

  Hi there, first of all, I asked this question on SuperUser.com, but no one there could help me. Well, we eventually got our Mac Mini Server. We now want to set up a small Remote Access VPN using this Mac Mini Server. Firstly we are not sure of the components needed additionally to the server to setup this VPN. We currently have the following: 1 Mac Mini Server 1 Firewall Router (Billion 802.11g ADSL2+ router with VPN capabilities [it says so on the box]), we currently use this as our internet connection and resides X.X.0.1 on our network. 4Mbps ADSL connection (Should this line have VPN capability enabled by the service provider?) We are not sure what else needs to be included to enable our small VPN. Any advice would be really helpful?

• Cookies blocked by router?

  - by Martin wiboe

  Hello, My friend has a D-Link DI-524 router that she uses for her home broadband. It's a pretty vanilla setup with the standard firewall settings, DHCP enabled etc. However, recently she has experienced something strange - cookies are not working on every computer on her LAN, whether using FF3.5 or IE8. I tried viewing the HTTP traffic using Fiddler2, and the requests come through fine (mind you, Internet browsing still works flawlessly) but whenever a website tries to set a cookie using the "Set-Cookie:" header, my computer sees that line as "Set-*ookie:" with the cookie contents removed. I have never seen anything like this - do you have any idea? Regards, Martin

• Have a service start on startup with Ubuntu

  - by Joseph Silvashy

  I'm not clear on how to start a service when the server boots, I read on some of the other questions asked about adding the script to /etc/init.d, but It's just one line that I need to execute in the commandline: sudo /etc/init.d/avahi-daemon restart But I have a few issues with this, firstly, I apparently need to use sudo, and it gives me the following: ngl-server-01:~% sudo /etc/init.d/avahi-daemon start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service avahi-daemon start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start avahi-daemon But when I try just avahi-daemon start I get: Too many arguments Why is this? and how would you start this service?

• Looking for FTP server that allows user management from database

  - by hughesdan

  I'm planning a server application that will handle files uploaded via FTP. The application must parse text documents that it receives and write them to a database (most likely a document-oriented database like Mongo). And the application must also relay all large binary files it receives to Amazon S3 for storage and hosting. I'd like to manage all aspects of the FTP server programmatically. For example, when a user registers via a web page the application should be able to create the user account in the database and provision a directory on the server for receiving files. I'm using a Linux server but am otherwise open to considering any programming language or framework. I experimented with VSFTPD but didn't like the way the application relies on config files and the creation of users and directories via the command line. Can someone please recommend what server framework I should consider? I'm a little biased toward solutions that leverage Javascript/Nodejs or Python. However, I'm open to anything that can run on a Linux box.

• Automate Windows 8.1 Enterprise upgrade

  - by Ben M.

  I have been trying to find the necessary command line switches for automating the upgrade for my Windows 8 clients to Windows 8.1. I have the ISO extracted and I've run setup.exe /? but that doesn't tell me enough. I can't find any relevant information from search engines. Can anyone point me to some documentation or information on how to automate the upgrade so that it keeps user data, programs, etc? I know how to do it when running the installer manually, but I obviously do not wish to do that with 100+ machines.

• iptables: How to read this OPT string?

  - by alex

  I have a simple INPUT rule for iptables that logs any new connections to a logfile. --log-tcp-options and --log-ip-options flags are both set and I get the appropriate OPT output. One line of my log looks something like this: Nov 29 17:00:00 IN=venet0 OUT= MAC= SRC=x.x.x.x DST=x.x.x.x LEN=64 TOS=0x00 PREC=0x00 TTL=53 ID=37898 DF PROTO=TCP SPT=57755 DPT=8888 WINDOW=65535 RES=0x00 SYN URGP=0 OPT (0204057D010303010101080A3E521D4D0000000004020000) I would like to understand how to interpret the OPT string (bold). Is there some documentation available on what it actually means? How could I make it human-readable?

• Folder/File permission transfer between alike file structure

  - by Tyler Benson

  So my company has recently upgraded to a new SAN but the person who copied all the data over must have done a drag n' drop or basic copy to move everything. Apparently Xcopy is not something he cared to use. So now I am left with the task of duplicating all the permissions over. The structure has changed a bit ( as in more files/folders have been added) but for the most part has been stayed unchanged. I'm looking for suggestions to help automate this process. Can I use XCopy to transfer ONLY permissions to one tree from another? Would i just ignore any folders/permissions that don't line up correctly? Thanks a ton in advance, Tyler

• PHP + Pear + IIS + WPI. How to uninstall?

  - by Half_Duplex

  I've installed PHP using the WPI, only to find out that I don't have the ability to install PEAR (not even sure that's true). So, now I want to uninstall PHP, but there are no options, not documentation, and the only thing I found was a hour long tutorial that required me to run a 300 line vbs (which blew up). Am I missing something here? Why is it this difficult to find documentation on this stuff?!? Is there an easier way to either get Pear 'installed' of getting PHP uninstalled so I can use the OTHER installer that lets me install Pear?
