  • Ubuntu mount hard drive confusing

    - by Fresheyeball
    I'm new to linux and have a home server set up running ubuntu. In the ui its very easy to mount my additional internal harddrives. I just double click on them. Since I have made this server headless, I now need to mount via the command line. How can I replicate the very simple double click gui behavior? So far all the information I've found is very complex. Ubuntu auto generated folders for each hd in under /media and I can see the harddrives under /dev but have no idea which is which as the hardware is identical between them. I also don't know how they are formated. Thanks in advance for any advice you have.

  • UIWebView paging / line cut off

    - by John
    Hi, I am trying to page a webpage, so disable scrolling, then the second page is the same webpage scrolled down the page height. The problem I have is that the bottom of the first page often has 1/2 a line of text, then the second page has the bottom half of the line. Is there a way to ensure the entire line falls on one of the pages? Similar to Stanza etc? Thanks

    - by woodgate
    I am actually using the pChart PHP library for generate graphs. I wanna know if it's possible to give a different line format for a graph with multiple series.

In the official documentation only appears a function that give format to the lines of all series: http://pchart.sourceforge.net/documentation.php?topic=pChart#setLineStyle Thanks a lot.

  • Should we hire someone who writes C in Perl?

    - by paxdiablo
    One of my colleagues recently interviewed some candidates for a job and one said they had very good Perl experience. Since my colleague didn't know Perl, he asked me for a critique of some code written (off-site) by that potential hire, so I had a look and told him my concerns (the main one was that it originally had no comments and it's not like we gave them enough time). However, the code works so I'm loathe to say no-go without some more input. Another concern is that this code basically looks exactly how I'd code it in C. It's been a while since I did Perl (and I didn't do a lot, I'm more a Python bod for quick scripts) but I seem to recall that it was a much more expressive language than what this guy used. I'm looking for input from real Perl coders, and suggestions for how it could be improved (and why a Perl coder should know that method of improvement). You can also wax lyrical about whether people who write one language in a totally different language should (or shouldn't be hired). I'm interested in your arguments but this question is primarily for a critique of the code. The spec was to successfully process a CSV file as follows and output the individual fields: User ID,Name , Level,Numeric ID pax, Pax Morgan ,admin,0 gt," Turner, George" rubbish,user,1 ms,"Mark \"X-Men\" Spencer","guest user",2 ab,, "user","3" The output was to be something like this (the potential hire's code actually output this): User ID,Name , Level,Numeric ID: [User ID] [Name] [Level] [Numeric ID] pax, Pax Morgan ,admin,0: [pax] [Pax Morgan] [admin] [0] gt," Turner, George " rubbish,user,1: [gt] [ Turner, George ] [user] [1] ms,"Mark \"X-Men\" Spencer","guest user",2: [ms] [Mark "X-Men" Spencer] [guest user] [2] ab,, "user","3": [ab] [] [user] [3] Here is the code they submitted: #!/usr/bin/perl # Open file. open (IN, "qq.in") || die "Cannot open qq.in"; # Process every line. while (<IN>) { chomp; $line = $_; print "$line:\n"; # Process every field in line. while ($line ne "") { # Skip spaces and start with empty field. if (substr ($line,0,1) eq " ") { $line = substr ($line,1); next; } $field = ""; $minlen = 0; # Detect quoted field or otherwise. if (substr ($line,0,1) eq "\"") { $line = substr ($line,1); $pastquote = 0; while ($line ne "") { # Special handling for quotes (\\ and \"). if (length ($line) >= 2) { if (substr ($line,0,2) eq "\\\"") { $field = $field . "\""; $line = substr ($line,2); next; } if (substr ($line,0,2) eq "\\\\") { $field = $field . "\\"; $line = substr ($line,2); next; } } # Detect closing quote. if (($pastquote == 0) && (substr ($line,0,1) eq "\"")) { $pastquote = 1; $line = substr ($line,1); $minlen = length ($field); next; } # Only worry about comma if past closing quote. if (($pastquote == 1) && (substr ($line,0,1) eq ",")) { $line = substr ($line,1); last; } $field = $field . substr ($line,0,1); $line = substr ($line,1); } } else { while ($line ne "") { if (substr ($line,0,1) eq ",") { $line = substr ($line,1); last; } if ($pastquote == 0) { $field = $field . substr ($line,0,1); } $line = substr ($line,1); } } # Strip trailing space. while ($field ne "") { if (length ($field) == $minlen) { last; } if (substr ($field,length ($field)-1,1) eq " ") { $field = substr ($field,0, length ($field)-1); next; } last; } print " [$field]\n"; } } close (IN);

  • Search files for text matching format of a Unix directory

    - by BrandonKowalski
    I am attempting to search through all the files in a directory for text matching the pattern of any arbitrary directory. The output of this I hope to use to make a list of all directories referenced in the files (this part I think I can figure out on my own). I have looked at various regex resources and made my own expression that seems to work in the browser based tool but not with grep in the command line. /\w+[(/\w+)]+ My understanding so far is the above expression will look for the beginning / of a directory then look for an indeterminate number of characters before looking for a repeating block of the same thing. Any guidance would be greatly appreciated.

  • Scripting a Windows 2008 Cluster from Windows 2003

    - by glancep
    Our current environment is all Windows 2003. When we migrate a new version of our service to the cluster, we first stop the service with a command like: cluster.exe <clusterName> resource "<serviceName>" /offline We do similarly after the migrate to bring the service back online. Now, we are upgrading our environment to new Windows 2008 servers. However, our build/migrate machine will remain Windows 2003. When issuing the same command from Windwos 2003 to Windows 2008, we get: System error 1722 has occurred (0x000006ba). The RPC server is unavailable. We need to be able to remotely administer a Windows 2008 cluster from a Windows 2003 server in an automated fashion (such as the command-line cluster.exe utility). Is this possible? Thanks, Gideon

  • trouble backing up large mysql database

    - by Patrick
    I have a wordpress MU database with something like 10,000+ tables for various user's blogs. I need to upgrade wordpress MU to newest version, but want to backup the DB before hand. PHPMyAdmin fails to even load the page when i click export. Ive tried going into the server (windows) and using dos command line: mysqldump -u USERNAME -p PASSWORD> BACKUP.sql but it hangs for a minute and gives me the error: error 23: out of resources when opinging file '.\USERNAME\wp_1037_links.MYD' (Errorcode: 24) when using LOCK Tables What am i doing wrong, or should i be doing? Is PHPMyAdmin right for something this size? Is there a better way of doing this than the two methods i tried? **Note that this is not my site, so any suggestions as to the setup of the DB ill have to run by the owner. Im just here for WP related crap, this is kind of out of scope for what i was brought on to do.

  • CLI way of uninstalling a Windows update?

    - by radioact1ve
    Basically, what can be achieved by going to Control Panel Uninstall a Program View Installed Updates Right Click Uninstall, but through the command line? Looking for a way that works across the Windows platform but if (and according to my reading, most likely) it's version dependent so be it. Maybe something like: C:\command /uninstall "Security Update for Windows 7 for x64-based Systems (KB2705219)" Looks like using the KB would be great but wusa.exe works for the above example update but not for say "Security Update for Silverlight (KBXXXXXXXX)". Not much consistency. I'm really surprised there isn't much documentation on this. How does an app like WUInstall do it? Follow up question is how is that list of "View Installed Updates" populated? I've searched the registry like crazy hoping for an "UninstallString" or equivalent but only found references to the regular Add/Remove Programs list. Thought I would reference a StackOverflow question for another perspective.

  • Linux command to concatenate audio files and output them to ogg

    - by hasen j
    What command-line tools do I need in order to concatenate several audio files and output them as one ogg (and/or mp3)? If you can provide the complete command to concatenate and output to ogg, that would be awesome. Edit: Input files (in my case, currently) are in wma format, but ideally it should be flexible enough to support a wide range of popular formats. Edit2: Just to clarify, I don't want to merge all wmas in a certain directory, I just want to concatenate 2 or 3 files into one. Thanks for the proposed solutions, but they all seem to require creating temporary files, if possible at all, I'd like to avoid that.

  • Confusion over terminology SSH, Shell, Terminal, Command Prompt and Telnet

    - by byronyasgur
    I don't usually use SSH if I can get away with it, but if I have to I do of course, and I've seemingly done this for years while still managing to remain slightly confused about these different terms ... from my basic research, this is my understanding, could someone verify/correct this? Telnet ... before SSH, not secure SSH ... ( secure shell ) the general name of the system/protocol Shell ... short name for SSH Command Line/Command Prompt ... the windows version Terminal ... the Unix version, also used by apple. Two further questions: What is the Linux version commonly called, is it just called SSH ? What is bash ?

  • Make blink(1) blink a specific color

    - by dimo414
    I'm playing with my new blink(1), and trying to hook it's command line interface into some of my programs, but the docs are a little limited and I'm struggling to figure out how to run even some seemingly simple commands. In particular, the CLI docs say: Usage: blink1-tool <cmd> [options] where <cmd> is one of: .... --blink <numtimes> Blink on/off .... So I try to run blink1-tool --blink 5 and it outputs blink 5 times rgb:0,0,0: and doesn't light up. How do I use the --blink command?

  • WPF: Same line drawn different?

    - by stefan.at.wpf
    Hello, I have a canvas and in it I'm drawing some lines: for (int i = 1; i >= 100; i++) { // Line LineGeometry line = new LineGeometry(); line.StartPoint = new Point(i * 100, 0); line.EndPoint = new Point(i * 100, 100 * 100); // Path Path myPath = new Path(); myPath.Stroke = Brushes.Black; myPath.StrokeThickness = 1; // Add to canvas myPath.Data = line; canvas1.Children.Add(myPath); } Well, nothing special, but it makes problems - the lines are drawn different! The canvas is inside a scrollviewer, the following image shows different positions of the canvas, however the lines should look the same? Hell, how is this possible? The code above is the only code I've written by hand and it's the only content in the canvas. Anyone knows why this happens and how to prevent this? Thank you very much!

  • Biztalk Flat File Schema - how to accept a LF or CRLF as the line delimiter

    - by FullOfQuestions
    Hi, Our client sends us a flat file as input, which we then take and convert to an XML file before sending to the destination system. The flat file consists of multiple lines, each line is delimited by LF or CRLF. How do I create a Flat File Schema so that Biztalk can interpret each line of data regardless of whether the line was delimited by LF (0x0A) or CRLF (0x0D 0x0A)? Thank you in advance, M

  • Command-line options for HH and opening CHM Windows Help Files

    - by Jeromy Anglim
    I'd like to be able to write Inquisit scripts in Vim. In the standard Inquisit application for writing scripts, I can press F1 and it brings up help on the topic related to the word under the cursor. I'd like to set up the same functionality through Vim. The help file for Inquisit is stored in a Windows .CHM file. I figured there must be a set of command-line options for doing a keyword search in a chm file, but I haven't been able to find a complete list of the command-line options, presumably for HH.exe. I did find this page with a few pointers, but it does not have a full listing of command-line options. I also found this discussion on AutoHotKey discussion board. It mentions keyhh. I also just found a vimscript designed to do exactly what I want Questions: Is there a complete list of command-line options for HH.exe? Is there a better way of going about what I am trying to do?

  • Text Terminal Hardware (for Linux)

    - by DLH
    Is there any way to obtain a hardware text terminal (preferably small in size) with a screen and a keypad to connect to a Linux machine (preferably via usb)? I'd like to be able to log into a command line and do some work there while simultaneously running a graphical environment on the main display. It seems like there should be some kind of lcd screen and qwerty keypad device designed for this purpose. Does this exist, and how do I get one? Edit: I'd be happy with a small networked device as well, as long as I could get a remote terminal into my computer.

  • Video Thumbnails using ffmpeg

    - by LenzM
    I'm looking for a nice short easy way to create a series of thumbnails for any given video file. I'm almost there using ffmpeg, here's what I have: ffmpeg -i /tmp/video.avi -r 1 -ss 60 -r 1 foo-%03d.jpeg` The only problem is that this takes a shot every second and I'd like to make it every minute or so. I tried setting the -r value to 1/60 or .02 to no avail. For reference, here's the old script I was using that only worked for some files: #!/bin/bash # grab a screenshot every 60 seconds file=$1 orig_dir=`pwd` mins=`exiftool "$file" | grep "Duration" | awk -F : '{print $2}' | grep --only-matching '[0-9]*'` dir="$file-screenshots" mkdir "$dir" cd "$dir" mplayer -vo png -vf screenshot -sstep 60 -frames $mins -ao null "../$file" cd "$orig_dir" This doesn't have to be on the command line, it's just that it always ends up being easiest.

  • Using sed for introducing newline after each > in a +1 gigabyte large one-line text file

    - by wasatz
    I have a giant text file (about 1,5 gigabyte) with xml data in it. All text in the file is on a single line, and attempting to open it in any text editor (even the ones mentioned in this thread: http://stackoverflow.com/questions/159521/text-editor-to-open-big-giant-huge-large-text-files ) either fails horribly or is totally unusable due to the text editor hanging when attempting to scroll. I was hoping to introduce newlines into the file by using the following sed command sed 's/>/>\n/g' data.xml > data_with_newlines.xml Sadly, this caused sed to give me a segmentation fault. From what I understand, sed reads the file line-by-line which would in this case mean that it attempts to read the entire 1,5 gig file in one line which would most certainly explain the segfault. However, the problem remains. How do I introduce newlines after each in the xml file? Do I have to resort to writing a small program to do this for me by reading the file character-by-character?

  • Why does VIM say there is trailing whitespace on this command?

    - by Jesse Atkinson
    I am trying to write a beautify CSS command in vim that sorts and alphabetizes all of the CSS properties as well as checks to see if there is not a space after the colon and inserts one. Here is my code: nnoremap <leader>S :g#\({\n\)\@<=#.,/}/sort | %s/:\(\S\)/: \1/g<CR> :command! SortCSSBraceContents :g#\({\n\)\@<=#.,/}/sort | %s/:\(\S\)/: \1/g These work independently. However, I am trying to pipe them into one command. On save VIM says: Error detected while processing /var/home/jesse-atkinson/.vimrc: line 196: E488: Trailing characters Any ideas?

  • Batch processing multi-TIFF in Irfan view

    - by hemalshah
    I have to convert DPI of more than 5k Tiff images on a monthly basis from 200x200 to 100x100. I can do that in Irfan view using a .bat file that i have created.. the following is the .BAT file code @"c:\program files\irfanview\i_view32.exe" "e:\batch1*.tif /aspectratio /resample /tifc=4 /dpi=(100,100) /convert=e:\batch2*.tif" %* Where tifc=4 is Fax 4 compression However, the above code doesn't help me change the DPI for other pages except for Only the first page in the tiff thats getting converted to 100 DPI. Rest all pages are still 200 DPI. I am using WinXP Professional and Irfan View. Can anyone tell me what I am missing. Or any other alternative program where I can create a .bat file and run the batch process using Command line?

  • plot of multiple line segments on 2D plot in Mathematica

    - by Bruce
    Hi, I would like to plot multiple, perhaps thousands of line segments on a single 2D plot in Mathematica. These line segments would be determined from an algorithm that would detected and save each segments endpoints. Once the algorithm has determined all the line segments within a finite 2D plot domain and range (e.g., x = 0,4 and y=0,0.5), I would like to plot them all on a single plot. Thanks for any suggestions.
