• Is it possible to have .bashrc outside home directory?

  - by FSchmidt

  I want to put a .bashrc file in a directory where my application is located, to set up path variables accordingly independent of the location of the directory at the moment. At the same time, I want to be able to run the application right away, without having to source a shell file to set the path every time. Therefore I figured I could use .bashrc which is executed when the non-login terminal is started. If I do put it in the proper .bashrc in the home directory, I would have to give an absolute path which I want to avoid. Is there a way to have something like .bashrc but not in home directory (ie a shell that is executed when terminal is started?)

• how to read the password from variable?

  - by Viswa

  I am trying to move my file to another system which is located in some other place, with this command: rsync -avrz src destination It works fine. But what I need is to put this command in shell script and run it like: #! /bin/sh rsync -avrz srcfilelocation destination When it runs, it asks for the destination system password. I know that password and give it manually. Now I have decided to assign the password to an environment variable, like pswd="destination system password". I need my shell script to read the password from this variable. How can I write a script to do this?

• Need some advice on CLI design, I need to provide simple but powerful command line options

  - by howtechstuffworks

  I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

• Why does Evolution give me multiple reminders for the same event?

  - by Dylan McCall

  I have a bunch of calendars on my Google Calendar account (school & work, personal, etc.), so I have Evolution subscribed to each one of those calendars. When I get a notification for an upcoming (recurring) event, I actually get many notifications for the same event, all at the same time. For example, just now I got 21 notifications for one event. I am using Gnome Shell, where the message tray displays event notifications in its own way. I get the same behaviour on my other computer, also running Ubuntu 11.10 with Gnome Shell. (And it has happened running Unity where Evolution only shows its dialog window with event reminders, but I'm not sure if it has happened quite as intensely). Does someone know why this is happening, and maybe how to fix it? It would be cool to get slightly less panic-inducing event reminders :)

• Nginx/puma rhel unix socket permission error?

  - by Kevin Brown

  When I try to start my puma server, I get the error: /.rvm/gems/ruby-2.1.1/gems/puma-2.9.0/lib/puma/binder.rb:275:in `initialize': Permission denied - connect(2) for "/var/run/nvhbase.sock" (Errno::EACCES) My sites-available/nvhbase.conf file: upstream nvhbase { server unix:/var/run/nvhbase.sock; } server { listen 80 default_server; server_name 207.131.132.219; root /home/vf032500/dev/nvh/public; location / { proxy_pass http://unix:/var/run/nvhbase.sock; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } I don't know a lot about unix sockets and everything works fine using tcp/puma default. My rails app is in my user directory. Is that the problem?? socket is starting in /var/run--I can start in /tmp, but I've heard that's bad practice? Provided I start the server in /tmp, I then can't access it via the server's ip--then what? I'm happy to provide any needed info, I just don't know a whole lot about server/nginx/puma.

• Strange display language in gnome shell

  - by khalafuf

  I logged in gnome-shell, and found that the display language is set to some strange asian language (I think) without my prompt. I tried to change the locale settings but found that the default language is English (how?) despite of that strange language. Here's a snapshot, See the strange word instead of "Activity": I'm on Ubuntu 12.04 LTS. Output of locale: LANG=zh_CN.UTF-8 LANGUAGE=zh_CN:en_US:en LC_CTYPE="zh_CN.UTF-8" LC_NUMERIC=en_US.UTF-8 LC_TIME=en_US.UTF-8 LC_COLLATE="zh_CN.UTF-8" LC_MONETARY=en_US.UTF-8 LC_MESSAGES="zh_CN.UTF-8" LC_PAPER=en_US.UTF-8 LC_NAME=en_US.UTF-8 LC_ADDRESS=en_US.UTF-8 LC_TELEPHONE=en_US.UTF-8 LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=en_US.UTF-8 LC_ALL= Output of locale -a: C C.UTF-8 de_CH.utf8 en_AG en_AG.utf8 en_AU.utf8 en_BW.utf8 en_CA.utf8 en_DK.utf8 en_GB.utf8 en_IE.utf8 en_IN en_IN.utf8 en_NG en_NG.utf8 en_NZ.utf8 en_PH.utf8 en_SG.utf8 en_US.utf8 en_ZA.utf8 en_ZM en_ZM.utf8 en_ZW.utf8 POSIX zh_CN.utf8 zh_SG.utf8 Solved: This answer did it.

• Cleaning up a folder structure from Visual Studio artifacts from the shell

  A few years ago I wrote a post that showed how to write a NAnt script to clean a folder structure from the artifacts folders used by Visual Studio. Today what I wanted to show you is a way that doesnt require NAnt installed on your computer, but that uses just a very simple command for Windows shell. Actually, its just a very tiny variation of the same command that Jon Galloway wrote to clean a folder structure from SVN files. But without further ado, here it is: Windows Registry Editor...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Ubuntu, OpenSuse, the world of linux for a web-developer

  - by SonofWatson

  I'm learning web development. My main OS is windows 7 but I've used Linux and currently dual-booting with Ubuntu. My Linux knowledge however, is pretty limited. I can work with the command line on simple tasks but that's pretty much it. I don't do any shell scripting, don't know very well the most important commands, nor the system in general. I am interested in web development. Should I get myself familiarized more with Linux ? Is it a must for future job positions considering my field of interest?

• gnome-shell failed to launch when dual monitor detected, nvidia card

  - by Terry Hu

  I installed a clean precise. I like gnome-shell so I installed it. It worked well with single monitor. But It does not work well when I go to office, plug my external monitor onto my laptop. I am using nvidia driver. Another colleague is using the same laptop, he can work well with dual monitors. His laptop is ATI graphic card. When I plug my extended monitor cable, I choose GNOME, but actually it goes to gnome 2 classic desktop environment, not GNOME 3. When I disconnect the extended monitor, restart X, I can login with GNOME3. Do I have to choose between GNOME3 and extended monitor? It's a hard choose.

• How to install Pear Linux's shell in Ubuntu?

  - by Emerson Hsieh

  For people who doesn't know what Pear Linux is: Pear Linux is a French Ubuntu-based desktop Linux distribution. Some of its features include ease-of-use, custom user interface with a Mac OS X-style dockbar, and out-of-the-box support for many popular multimedia codecs. Excerpt from Distrowatch. When this Linux Distribution came out, I immediately went to the website and found out that Pear Linux is actually Mac OSX with a pear. I was going to download it and install Pear Linux as a triple-boot on my computer (Windows and Ubuntu installed). Then I remembered that Pear Linux is Ubuntu based. So I thought of a better Idea of installing only the Comice OS Shell in Ubuntu(the Desktop environment of Pear Linux), so that I can select that in the login screen. Is that possible? EDIt: Found this.

• Executing Shell Commands - PHP or Python?

  - by chadpeppers

  I know basically two languages: Python and PHP. I am primarily a Drupal developer. I have a great idea in creating a command line program that will help some of the mundane tasks and bring my efficiency up quite a bit. The concept is that of a complete console program, almost like the days when I learned C++ using stdin/out. I want to use this came concept but for this program. I am going to be executing shell commands (mainly drush commands, if you are familiar with drush its drupals way of doing tasks like installing drupal, clearing cache, and other things). I am also wanting to do a database and save/execute through multiple objects and site profiles. My general question is this. Which language would be better suited to handle command line code? Drupal is written in PHP so I am leaned more towards that,but I know python seems to handle console programming a bit easier. Any help would be great!

• Live CD doesn't boot, drops to Busy Box shell

  - by D3c3nt Boy

  I am a Windows user and I'm keen to shift to Linux, so I made live CD of Ubuntu 10.10 (Maverick). This is my very first time to use Ubuntu. I put CD in the drive and set the BIOS to boot it, and the Ubuntu CD worked and logo of Ubuntu appears on screen. But suddenly before the start up screen it shows this: Busy Box v 1.5 (Ubuntu 1: 1.15.31 ubuntu5) built in shell (ash) enter help for a list of built in commands When I type help and press enter, the list of commands appear like below: alias break cd chdir command continue echo eval exec export ... This is my first time so i have no idea what to do. I restarted my pc several times but it happens every time. Please help me. What should I do?

• Use Classic Shell to Get a Classic Start Menu & Explorer Toolbar in Windows 8

  - by Chris Hoffman

  Classic Shell is an open-source utility that brings classic Windows features to newer versions of Windows. It offers the most classic Start menu for Windows 8 yet, and it lets you avoid the ribbon with a Windows Explorer toolbar. We’ve also written about getting a Windows 7-style Start button with ViStart and a Metro-style Start menu with Start 8. Or, if you’re brave, dive into the deep end and try living without the Start button for a while.

• Gnome shell crashing in 11.10 with 'purple haze' effect

  - by Andy

  I've just got Gnome with 11.10 up and running with my netbook and liked it so much I thought I'd get my parents old machine sorted with Ubuntu too. Unity works fine but when I try to switch to Gnome shell, I get problems. On login, the wallpaper appears as normal but then the colour bleeds out from the centre, leaving traces of it around the edge in a purple haze (yes, I do like Jimi Hendrix but I'm not making this up). When I go to applications, typing then pressing enter in the search field dumps me out so there's nothing but File / Edit / View etc in top left; starting a program seems to work but then there's only a white screen and no program window. Gnome classic works fine, from the limited use I've given it. I'm using an Asus desktop with ABIT motherboard, 2.6ghz with 1gb RAM; I've checked drivers and it says I'm up to date, Nvidia graphics. Anyone any ideas?

• Dual monitor gnome-shell broke itself

  - by JXPheonix

  Ok, lets get this over with. I have a dual-monitor, ati setup on gnome-shell that was just fine until this morning. Then, this happened. Look closer... Whatever has happened to my ubuntu setup? My second monitor still works, entirely normally, with the exception that I cannot (obviously) access activities (as i am in gnome-fallback ). I do wish to resume my work... EDIT: By entirely normally, I mean I can move my mouse over it and have seperate windows on it and stuff. It's not mirroring. UPDATE: Unity works entirely normally.

• How do I clear all gnome shell notifications?

  - by user19448

  I use Jupiter as a power manager. Now I get a good number of notifications from it. I do not have problem with the fact that I get all these notifications. I do however, want to be able to clear all gnome shell notifications with a few clicks. Currently, my entire bottom edge of the screen is filled with notifications and I do not wish to clear each item one by one. So my question is, how do I clear these notifications? If this is not possible in the ui, is it possible to write an extension to do it? Where should I suggest this feature to gnome developers? Gnome forums are almost dead now, the administrator has not activated my created account since 5 days!

• gnome shell with very high CPU usage

  - by 501 - not implemented

  i'm running ubuntu gnome 13.10 on my dell latiude e6510 with a i5 m560. The I5 comes with a embedded Intel HD 3400 Graphics. The average cpu usage of the gnome-shell is by 160% it's to high, I think. Is there a problem with a driver? If i call the command glxinfo | grep OpenGL it returns: OpenGL vendor string: VMware, Inc.

• Get the Windows 7 Start Menu Back in Windows 8 with Classic Shell

  - by deadlydog

  I just thought I’d give readers a heads up that you can use Classic Shell to get the old Windows 7 style of start menu back instead of using the new crappy Windows 8 metro start screen; plus it’s free and open source .  You can still access the metro start screen with Shift+WindowsKey or Shift clicking the start menu button.  This program also defaults to showing the desktop on startup instead of the metro start screen (but that can be disabled), and is super configurable and has tons of options to tweak it just the way you want if you are picky like me   The only thing I would say is when installing the app, only install the Classic Start Menu; you don’t need the other ones. You’re welcome, and happy coding!

• Ubuntu 11.10 Gnome 3 shell doesn't have the Activities menu or launcher

  - by Kelly

  I installed it from apt-get and it only has Applications and Places instead of the Activities menu, it also doesn't have the dock or launcher. Using the super key does nothing, as neither does mousing to the upper left corner. I have also installed the tweak tool, but it looks like all the settings are not being applied to the UI. Am I missing something. I have never used Gnome 3 before as I recently upgraded from Ubuntu 10.4, which I believe was Gnome 2 for the shell. I have been reading the documentation on the Gnome site and it says there should be an Activity menu and other items that aren't there. Thanks
