• Determining End of Line Delimiter

  - by Michael Merchant

  How do you verify what the delimiter for a file is? I'm using eclipse to edit a script file on my windows system that I use to deploy on my unix server. The script specifies file names and I'd like to be certain that eclipse is saving the files with unix end of line delimiters. I've set my preferences to use the Unix Line Delimiter on new files using: Window > Preferences > General > Workspace > "New text file line delimiter" And have changed my script file's line delimiter using. File -> Convert Line Delimiters To Is there a way (preferably with the eclipse IDE) to check that there is no "\r"?

• Piping the output of a program to Preview.app

  - by Abhay Buch

  I'm using an application (the dot program of the graphviz library) that generates a wide variety of file formats including PostScript and PDF. It can send the result to stdout or to a file. I'm currently sending it to a file and opening it with Preview. Is there any way to pipe the output and have it be read by Preview, so that I'd don't have to generate a file and have it lying around? This is going to be used by a number of people who won't know the internal structure of the generating script and I don't want to clutter their folders or complicate their lives. More generally, is there any way to take a program that sends its output to stdout and pass that output to an program that usually takes it's input from a file, without actually creating a file?

• "sh: /usr/sbin/xenstored: not found" - But it's there?

  - by Matt H

  What would cause running the file /usr/sbin/xenstored to print sh: /usr/sbin/xenstored: not found However, the file /usr/sbin/xenstored is there and is not a symbolic link. Actually I should be running this as root. That prints a similarly odd message. sudo: unable to execute /usr/sbin/xenstored: No such file or directory By the way, xenstored is not a script, it's an ELF executable. My guess is that it's because I haven't gotten all the dependent libraries installed. However, I would expect it to say something like this: ./xenstored: error while loading shared libraries: libxenctrl.so.4.0: cannot open shared object file: No such file or directory Which is true of running xenstored on a system that doesn't have all the required libraries. Why do I get "not found" vs the much more useful "cannot open shared object file"?

• Varnish doesn't seem to be caching

  - by Charlie Somerville

  I've setup a Varnish cache mirror to sit in front of a file server, but it seems to be endlessly re-downloading data from my file server. There's about 100GB of data in total, but so far Varnish has downloaded 800GB from my file server. I'm using the default VCL file that comes with Varnish and the response headers for files served by the file server are similar to the following: HTTP/1.1 200 OK Cache-Control: max-age=290304000, public Content-Type: image/jpeg Expires: Wed, 29 Dec 2010 21:38:33 GMT Server: Microsoft-IIS/7.0 E-Tag: "8b4723296ab697530768f18b1378b269" Content-Disposition: inline; filename=image046.jpg; X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Thu, 23 Dec 2010 05:38:33 GMT Content-Length: 100592 I'm starting varnishd with the following options: varnish/sbin/varnishd -a 0.0.0.0:80 -f varnish/etc/varnish/default.vcl -s file,varnish/var/lib/varnish/varnish_storage.bin,100G

• Microsoft secure downloader not finishing download

  - by Goran_Mandic

  I am downloading Windows 8 RTM using Microsoft's secure downloader provided by my school's DreamSpark account. The OS I'm currently on is Windows 8 preview. Once the download reaches 100%, it restarts to 0%. I open the download path folder, and find the en_windows_8_x64_dvd_915440.sdc file and the en_windows_8_x64_dvd_915440.scd.log file. The log file contains only one line : "Unpacking File: C:\Users\en_windows_8_x64_dvd_915440.sdc" I was unable to unpack the file using 3rd party software, and there seems to be no official software made for unpacking this type of file. What can I do to avoid downloading the OS illegally, even though I have my own product key?

• Using cookies with lynx

  - by XXL

  lynx -cfg=cfg.file $URL this works with the following contents of the .cfg file: SET_COOKIES:TRUE ACCEPT_ALL_COOKIES:TRUE PERSISTENT_COOKIES:TRUE COOKIE_FILE:cookie.file however, this does not: lynx -cookies=1 -accept_all_cookies=1 -cookie_file=cookie.file $URL if it's going to be of any help - here's the trace: parse_arg(arg_name=-cookies=1, mask=1, count=2) parse_arg lookup(cookies=1) ...skip (mask 1/4) parse_arg(arg_name=-accept_all_cookies=1, mask=1, count=3) parse_arg lookup(accept_all_cookies=1) ...skip (mask 1/4) parse_arg(arg_name=-cookie_file=cookie.file, mask=1, count=4) parse_arg lookup(cookie_file=cookie.file) ...skip (mask 1/4) parse_arg(arg_name=$URL, mask=1, count=5) parse_arg startfile:$URL obvious question, why? the actual difference, from what i see, is the inability to trigger "PERSISTENT_COOKIES:TRUE" by command-line options in lynx. or, maybe, i have overlooked/misunderstood something?

• Outlook 2007 Clients attachments not opening correctly

  - by Az

  Hello, Thanks for taking the time to read this. We are having an issue on our Terminal Server clients that has me perplexed. We are running Server2003 x64 and Exchange 2007 environment. When we attempt to open an attachment for example .jpeg and the user selects to open the file, it prompts them to select a program to open the file with. The file associations apear to be fine, if I save the document to the desktop and open it, it opens with the correct program automatically. If i select "always open using this program" it will then open automatically, but I don't want to have to do this for all file types we open regularly on each client. Is this some sort of Exchange server security setting that is forcing them to associate the file? Does outlook or exchange maintain its own file association database? Thanks for reading!

• Restore files from certain increments using Duplicity

  - by luckytaxi

  Given the following backup sets ... Found primary backup chain with matching signature chain: ------------------------- Chain start time: Tue Jun 21 11:27:26 2011 Chain end time: Tue Jun 21 11:27:59 2011 Number of contained backup sets: 2 Total number of contained volumes: 2 Type of backup set: Time: Num volumes: Full Tue Jun 21 11:27:26 2011 1 Incremental Tue Jun 21 11:27:59 2011 1 If i run the following command, it works (1308655646 was converted from Tue Jun 21 11:27:26 2011): duplicity --no-encryption --restore-time 1308655646 --file-to-restore ORIG_FILE \ file:///storage/test/ restored-file.txt However, if I run the following command, it restores the from the latest set. duplicity --no-encryption --restore-time 2011-06-21T11:27:26 --file-to-restore \ ORIG_FILE file:///storage/test/ restored-file.txt What am I doing wrong w/ the time? I prefer the second option only because I don't want to have to do the conversion manually.

• OWA (Outlook Web Access) won't give user a link to attached document. Gives "Open as Web Page"

  - by Jerry Mayers

  I have been testing OWA and have found that when there is an attached file on a message it shows the "Attachments:" then the file name (but no link) and then [Open as Web Page] link. The user has to click on that which opens a new window and previews the document, then the user gets "You are currently viewing:" followed by the file name. This time the file name is a link that they can open/download. This happens for Office documents and PDF file at least. How do I make it so users can get a direct link to the file on the original message window?

• pymatplotlib without xserver

• How do I force excel (and other office products) to stop opening files in the same application?

  - by KronoS

  Whenever I "double click" on an Excel file and another Excel file is open, the newly opened file automatically opens in the same application window as the previously opened Excel file. This isn't limited to just Excel, as I've seen Word do this as well. This poses a problem when wanting to compare documents side by side. The current solution I have for this is to actually open another Excel or Word instance, and then open the file from within that application window itself. Is there a way to force Office to open a new instance of the application when double clicking on the file icons? I'm currently using Office 2007 and Windows XP but I've seen this on Office 2010 and Windows Vista and 7. I'm looking for an overall solution if possible.

• Disable passwd history feature with remember=0

  - by user1915177

  PAM version - pam-0.79 Is setting 0 allowed on "remember" option in /etc/pam.d/common-passwd file of pam.d module to disable passwd history feature? With "remember=0" in /etc/pam.d/common-passwd file, I am observing a memfault when running the passwd command as a USER. When browsed the source, the function in _set_ctrl in support.c file of pam_unix module handles wrong values of remember, but currently its not robust enough to handle 0, which is a wrong value. So the valid and only option to disable history feature, is to not include the "remember" option in /etc/pam.d/common-passwd file and not to set-up /etc/security/opasswd file? Could see in the following link mention of setting "remember" to 0 has no effect to remember value in "/etc/security/opasswd" file. =https://lists.fedorahosted.org/pipermail/linux-pam-commits/2011-June/000060.html

• How to store data on a machine whose power gets cut at random

  - by Sevas

  I have a virtual machine (Debian) running on a physical machine host. The virtual machine acts as a buffer for data that it frequently receives over the local network (the period for this data is 0.5s, so a fairly high throughput). Any data received is stored on the virtual machine and repeatedly forwarded to an external server over UDP. Once the external server acknowledges (over UDP) that it has received a data packet, the original data is deleted from the virtual machine and not sent to the external server again. The internet connection that connects the VM and the external server is unreliable, meaning it could be down for days at a time. The physical machine that hosts the VM gets its power cut several times per day at random. There is no way to tell when this is about to happen and it is not possible to add a UPS, a battery, or a similar solution to the system. Originally, the data was stored on a file-based HSQLDB database on the virtual machine. However, the frequent power cuts eventually cause the database script file to become corrupted (not at the file system level, i.e. it is readable, but HSQLDB can't make sense of it), which leads to my question: How should data be stored in an environment where power cuts can and do happen frequently? One option I can think of is using flat files, saving each packet of data as a file on the file system. This way if a file is corrupted due to loss of power, it can be ignored and the rest of the data remains intact. This poses a few issues however, mainly related to the amount of data likely being stored on the virtual machine. At 0.5s between each piece of data, 1,728,000 files will be generated in 10 days. This at least means using a file system with an increased number of inodes to store this data (the current file system setup ran out of inodes at ~250,000 messages and 30% disk space used). Also, it is hard (not impossible) to manage. Are there any other options? Are there database engines that run on Debian that would not get corrupted by power cuts? Also, what file system should be used for this? ext3 is what is used at the moment. The software that runs on the virtual machine is written using Java 6, so hopefully the solution would not be incompatible.

• Why doesn't my htaccess redirect work?

  - by cosmicbdog

  I have setup a simple htaccess redirect which looks like this (this is the whole .htaccess file): Options +FollowSymLinks RewriteEngine On Redirect 301 /something http://something.com/something.php If I then load the site which contains this .htaccess, ie, myredirectsite.com/something I end up with the following 404: The requested URL /something was not found on this server. Apache/2.2.3 (Red Hat) Server at myredirectsite.com Port 80 And the logs: [Tue Jul 10 14:25:46 2012] [error] [client xx.xx.xxx.xx] File does not exist: /home/sites/scp/something Something is not a file, and something does not exist. I have assumed I could use Redirect the same as a Rewrite but it looks like the redirect needs to be for a file that actually exists? I created the file 'something' and it just attempts to load the blank file. No redirect. What am I missing in getting this working?

• Life Cycle Navigator?

  - by C.W.Holeman II

  In many environments the file system directory structure and naming conventions attempt to allow one to use a file manager to navigate the life cycle of a document. This overloading of functions makes it difficult for users to handle the complexity. A file browser is a tool that lets the user navigate among files located in a directory structure to find a specific file. Whereas, when given a specific file, a life cycle navigator is a tool that lets the user navigate its life cycle from source to published copy and across versions. Does a Life Cycle Navigator exit? I see a user pointing at an object: Left mouse button displays the document Right mouse button has a Life Cycle Navigator (LCN) The LCN displays a tree for a specific document within a file manger, for example: Published 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All Source Draft 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All +Work Flow +Properties Or from a command line: $ lcn x.pdf --open_source_document | my_favorite_editor $ lcn x.pdf --show_published_version_info $ lcn x.pdf --show_previous_publish_versions_info See also, Life Cycle Navigator.

• How to give write permissions to multiple users?

  - by Daniel Rikowski

  I have a web server and I'm uploading files using an FTP client. Because of that the owner and the group of the file are taken from the user used during the upload. Now I have to make this file writable by the web server (apache/apache). One way would be to just change the owner and the group of the uploaded file to apache/apache, but that way I cannot modify the file using the FTP account. Another way would be to give the file 777 permissions. Both approaches seem not very professional and a little bit risky. Are there any other options? In Windows I can just add another user to the file. Can something similar done with Linux?

• How to work around Windows error 8x90070057?

  - by Chris

  So today I was trying to copy a simple .PDF file from a local folder on my machine to a network folder and every time I tried to move the file I would get an error dialog box which would state that I was passing a wrong parameter and give me the error code of 8x90070057. Does anyone know of a way to work around this error so that I can get this file copied? I have tried renaming the file with an underscore in front. I have tried copying from my local folder to my desktop and then to the remote folder. I have tried hunting down anything that might be using the file. An example of the file name is: Flowers & Trees.pdf

• IIS configuration to publish files

  - by Andy.l

  I have a web service that will save a file that will be published externally through IIS. The idea was to use Webdav to save the file, but that would mean that the file could be altered externally as well. The idea is to have 2 website on the IIS server that I publish the file from. One site http://internalpublish.local/vfolder where vfolder points to a file share where the file would be saved through webdav. The other site would be http://externalpublish.com/vfolder where vfolder points to the same physical folder as on the internal site, but webdav is NOT enabled on this site. Would this cause any issues? Any feedback would be gratefully appreciated. /Andy.l

• Excel Document Size is at 0KB, can't be opened

  - by Bassam

  After I saved an Excel document, I remembered that I needed to change something in it, so I go back to open it and it said Excel cannot open the file, because the file format or the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file. I know when I saved before, around 2hours ago, it worked just fine. The document size is at 0KB now. How do I recover this document? Its crucial for my business!

• What will Time Machine do when

  - by Joel Budgor

  When Time Machine says "I will delete the oldest files first" does it mean this literally. Here is a theoretical example. Source Drive: 300 GB, consisting of 1 280 GB file and a 1 GB file. Backup Drive: 300 GB The initial backup will backup both files, using 281 GB. If I modify the 1 GB file 21 times, what will Time machine do when I run out of room on the backup drive; Delete the original 280 GB because it is the oldest file or delete the oldest version of the file I have modified 21 times. I hope it would delete the oldest version of the file I have modified 21 times, but I want to be sure. Thanks, Joel Budgor

• Vim: How can I :cd to an sftp directory?

  - by ChrisInCambo

  Hi, I'm currently an emacs user, but thought I would come back and take another look at Vim for fun. My client machine is Ubuntu, and I frequently work on other ubuntu servers within my network, emacs and tramp is really nice in this regard, I can just connect to a file via sftp and then easily navigate to it's parents/children/sibling, just as if I was dealing with a file on the local file system. With Vim I can sftp to a file, but none of the navigation stuff works, when I use :e or fuzzy file search, vim still thinks I'm back on the client machine. If I try to :cd to the sftp directory I get an error. Is there anyway I can get the same file/folder navigation regardless of whether I'm looking at an sftp folder or a folder on my client machine? Cheers, Chrsi

• Run BGInfo At Startup For All Users

  - by slickboy

  I have a Windows 7 image which I intend to deploy across a business. For simplicity I intend to install BGInfo on each machine and have it update each time a user logs in. From what I can see, when BGInfo creates a configuration file, the file contains variables which are local to each account - and therefore the configuration file will only work on the user account that created it. Has anyone any idea as to how make these configuration files 'generic' so that BGInfo will work for all accounts when they log in? At present I have the BGInfor application and a BGInfo configuration file saved on the C drive and I have written a batch file which is stored in the 'All Users/Start Menu/Startup' directory (which executes every time any user on the computer logs in), however this only works for the account which created the configuration file. Thanks for any help.

• How can I tell when an FTP is complete?

  - by identry

  I have a cron job that processes files that my client's upload via FTP to my FreeBSD server. The cron job runs once an hour, and normally processing each file only takes a few seconds. The cron job looks in the client's upload directory and moves any new files to a tmp directory. It then processes the file(s) and moves them into a final directory where they are then available to the public through a website. The problem is, every once in awhile, the cron job runs just as a new file is being uploaded. It moves the half-uploaded file to the tmp directory, and tries to process it, and fails, of course. Question: how can I determine if the uploaded file is complete? The only thing I can think of is checking the file size to see if it's changing, but that seems like a kludge. Is there some sort of flag or something that is set when the upload is complete?

• Logcat error: "addView(View, LayoutParams) is not supported in AdapterView" in a ListView

  - by HacKreatorz

  I'm doing an aplication for Android and something I need is that it shows a list of all files and directories in the SD Card and it has to be able to move through the different directories. I found a good tutorial in anddev: http://bit.ly/h4GyFC I modified a few things so the aplication moves in the SD Card and not in Android root Directories but the rest is mostly the same.
