  • Use `dd` linux program to save / recover a disk's MBR

    - by Graduate
    I have an Ubuntu OS installed on my laptop. I want to install Windows 7 as well to another disk partition (I will do it by recovering it from a special partition on my laptop). After installing Windows, I want to recover my hard drive MBR to be able to load Ubuntu. I have a plan to use linux dd program: 1) (Before installing, perform this command in Linux) dd if=/dev/sda of=/home/user/mbr_backup bs=512 count=1 2) (after installing, load Ubuntu Live CD and launch this) dd if=/home/user/mbr_backup of=/dev/sda bs=512 count=1 3) Load Ubuntu on PC and re-configure the GRUB2 to be able start Windows I need your advice, I want to be sure I won't damage the disk (it's partition table).

  • linux - Is Debian "lighter" than Ubuntu?

    - by user2983756
    I currently run Linux Mint 14 KDE on a "semi-old" machine I use for working and surfing the web - it was the first Linux system I ever used (running away from old Win XP), so I picked a complete system that would have most of my basic needs installed (I didn't even know what exactly all those needs were at the time). The thing is, my computer is becoming really old and Mint is a cluttered system, and for the next installation I'm going to try and install a "raw" system and get everything from the online repos. My question is: Since Ubuntu is Debian-based, does that make it consume more resources than its base system? If that isn't the difference, which one is "lighter" in that sense?

    Lets say I have fields: name, number, id I have a data file: name1|number1|id1|name2|number2|id2...etc I want to replace every 3rd pipe with a new line or '\n' so I get: name1|number1|id1 name2|number2|id2 I'm having no luck with awk or sed. I've tried the following, and variations of: awk '/"\|"/{c++;if(c==10){sub("\|","\n");c=0}}1' inputfile.txt sed 's/"|"/"\n"/2' inputfile.txt It tells me awk: syntax error near line 1 awk: illegal statement near line 1 awk: syntax error near line 1 awk: bailing out near line 1 Any help is greatly appreciated! EDIT: Thank you!

  • Using cd to go up multiple directory levels

    - by Tossrock
    I'm dealing with java projects which often result in deeply nested folders (/path/to/project/com/java/lang/whatever, etc) and sometimes want to be able to jump, say, 4 directory levels upwards. Typing cd ../../../.. is a pain, and I don't want to symlink. Is there some flag to cd that lets you go up multiple directory levels (in my head, it would be something like cd -u 4)? Unfortunately I can't find any man page for cd specifically, instead just getting the useless "builtins" page.

  • Remote Linux system via Windows 7

    - by kaila
    I have a dual boot with Windows 7 and Fedora. Though I can long into both without any problems, I am trying to log in to the linux account via the Windows account. Is that possible? Or, is it possible to access my university's linux server via telnet from home? I did so and got an error, with cold not connect to port 23 message. Also, since most of my mail accounts are on Windows, the passwords to which I have forgotten, I would prefer working on a ;remote' connection.

    Because there's no sudo command in Cygwin, scripts that I want to run fail with ./install.sh: line N: sudo: command not found What's the standard way for getting around this? Editing the scripts to remove sudo? Getting some sudo-like tool for windows?

  • The Command "File.BatchNewTeamProject" is not available in VSTS 2010

    - by TS
    Hi, I am trying to automate the creation of team projects using a command built into VS 2010 called File.BatchNewTeamProject using a project settings file as an argument, and executing this as a process silently in the background from my c# win app. I am aware of a requirement that Team Explorer has to be open and connected to TFS before this command can run, however, when I start a process with devenv.exe, a fresh instance of visual studio pops up with Team Explorer not connected by default. How can I solve this problem?

  • Eclipse Plugin that Opens a Command Line in Eclipse

    - by Jonas Laufu
    I'm looking for an Eclipse plug-in that shows a system (independent) command line in a view that is ideally synchronized with the current project's local path. So basically a shell within Eclipse. The reason for this is to be able to execute custom build commands and script faster than specifying them as launch configurations or having to open a command prompt every time I start eclipse.

  • Windows version of the Unix touch command

    - by Paul Hargreaves
    I'm looking for a Windows port of the UNIX touch command. I don't want to install an entire MKS toolkit just for the one tool. Is there a native port available somewhere or a command in Windows that does the same thing and supports features like all files in a directory by wildcard? Specifically I'm after changing mtime, ctime and atime for a project that reports ages of files based on... mtime, ctime and atime.

  • What does the :compiler command do in Vim?

    - by Martín Fixman
    I recently found that there is a command in Vim called compiler. You can call it with any common compiler (for example, :compiler gcc, :compiler php, etc.), but it doesn't seem to have any immediate effect. I searched on the manpages but didn't find anything useful about what it actually does, nor does the Vim Wiki. Does anyone know what that command actually does?

  • interactive lua: command line arguments

    - by mr calendar
    I wish to do lua prog.lua arg1 arg2 from the command line Inside prog.lua, I want to say, for instance print (arg1, arg2, '\n') Lua doesn't seem to have argv[1] etc and the methods I've seen for dealing with command line arguments seem to be immature and / or cumbersome. Am I missing something?

  • How to escape parameter in windows command line?

    - by Rryk
    I need to run the following command from the command line in Windows 7: SumatraPDF.exe -inverse-search "\"C:\Program Files\eclipse\inverse_search.bat\" \"%f\" %l" However I need to modify it a little, since my installation of Eclipse is located in here: C:\Program Files (x86)\Eclipse (C++) How do I escape this line correctly? Do I need to escape parenthesis and pluses too? Or is it just enough to escape double quotes?

  • Patterns for wrapping a command line tool in another language

    - by Tom Duckering
    I'm currently writing some Java to wrap around an extensive command line tool. It feels like I'm writing a lot of similar code. I'm wondering if there are any established patterns for wrapping command line tools - passing arguments and handling output and so on. Specific examples in Java would obviously be great, but any general suggestions or pointers are welcome too.

  • Copying eclipse projects through command line?

    - by Richie
    Hi, Does anyone know if it is possible to copy an existing project into a new, created workspace on the fly? I can create the workspace already through command line. I am thinking I either need to copy the whole project into another workspace (possible through command line?) or create a new project and copy the .classpath and .project folders. Any help is appreciated. Thanks, Richie
