• Development on Terminal or IDE [on hold]

  - by Taylor Flores

  I've been using nano, make, gcc, and gdb for 6 months now and I've found it much easier than using VS or Codeblocks. But I'm wondering now: Is development on a terminal more/less efficient that using an IDE? In what situations is one preferred more sensible than the other? I'm not asking about opinions, I want to know if there's specific reasons to use one over the other. From what I can gather: terminals can be used on environments where a GUI is not available terminal projects can be created and configured more quickly IDEs contain better syntax highlighters (ie identity highlighters) This question is C biased, but I think it's relevant to other languages as well.

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• What does "0 is wrong flag id" mean?

  - by Andreas

  When I edit system files, for example when I edit rules for my trackpoint using this command: gksu gedit /etc/udev/rules.d/trackpoint.rules I get the following errors in the terminal (after closing gedit and saving the file): error: line 10034: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 19814: 0 is wrong flag id error: line 23363: 0 is wrong flag id error: line 23363: 0 is wrong flag id error: line 26005: 0 is wrong flag id error: line 26005: 0 is wrong flag id error: line 26846: 0 is wrong flag id error: line 26846: 0 is wrong flag id error: line 28718: 0 is wrong flag id error: line 31695: 0 is wrong flag id error: line 31695: 0 is wrong flag id error: line 35272: 0 is wrong flag id This goes on up until line 150400. The changes are applied as desired, but can somebody explain the error to me as I'm a newbie and just trying to get a clue about the terminal.

• Terminal as desktop background instead of wallper

  - by Janis Erdmanis

  I have come to conclusion that all my needs from nautilus is satisfied with terminal and last file manager. It also dismisses the need for multiple nautilus instances, which makes mess when I forgot how I meant to use different workspaces. The next step for my simplification would be to get rid of any possibility to open nautilus. Also I thought that my interaction with computer is file centred, therefore it makes sense to leave file manager in background of applications. Are there any ways to make terminal as desktop background with which I could interact?

• Git does not ask for passphrase during pull/push in terminal

  - by Damian

  I'm trying to use git from the terminal in my Ubuntu 12.04 desktop. My repository is hosted in Github, and I have the a key for my desktop. Whenever I do either "git pull" or "git push," a dialog box will pop up asking for my passphrase. This works fine if I type the passphrase correctly. However, if I'm connected to my desktop through ssh and do a git pull or push, the command does not prompt the passphrase and it outputs the following error: Permission denied (publickey). fatal: The remote end hung up unexpectedly This error makes sense because I'm not inputting my passphrase. So the question is, how can I get the passphrase prompted in the terminal? Thanks!

• sudo: source: command not found

  - by HorusKol

  I've been updating some of the default profile for bash, and saw from the tutorials I was following that I could reload the new profile with the new environment settings by using: source /etc/bash.bashrc The only thing is - the new environment variables were only available to my current user - and were ignored when I used sudo. They only became available to sudo when I closed my terminal session and rejoined. When I try to use: sudo source /etc/bash.bashrc I get the error: sudo: source: command not found Is there a simple way to load in the new bash profile settings for sudo without having to close the terminal and restart?

• Ubuntu boots into terminal

  - by DKuntz2

  When I turn on my computer (a CR-48), I keep loading tty1. I have tried xstart, and all I get is: Fatal server error: Could not create lock file in /tmp/.tX0-lock When I attempted to make the directory (both sudo and not), I received these two errors: sudo: Can't open /var/lib/sudo/don/tty2: Read-only file system (I've gotten other tty's for different virtual terminals) mkdir: cannot create directory '/tmp/tX0-lock': Read-only file system Before I got to the only terminal state, I had the computer moving a few files from a network server to the computer, I put it to sleep without stopping the transfers, and started the computer again away from my home network, and attempted to stop the transfers, the computer than restarted. Running sudo reboot puts me right back in the virtual terminal, and I can't get into any sort of x application.

• Setting proxy from terminal

  - by baltusaj

  I have tried changing my proxy settings in a terminal as: export HTTP_PROXY=http://10.1.3.1:8080 and export http_proxy=http://10.1.3.1:8080 but when I try to install a new package or update apt-get, apt-get starts displaying messages from which it seems it is trying to connect to a previously set proxy: sudo apt-get update 0% [Connecting to 10.1.2.2 (10.1.2.2)] [Connecting to 10.1.2.2 (10.1.2.2) I have tried setting the proxy via bashrc file but that din work either. As far as I remember 10.1.2.2 was set using GNOME GUI but I don't have access to the GUI right now so I am trying to set it from terminal.

• 12.04 - Disable the HUD trigger key [ALT] in Emacs & Terminal

  - by EoghanM

  An answer on How to disable HUD in Unity 2D? points to https://bugs.launchpad.net/unity-2d/+bug/947613 where the ALT key will be made reconfigurable. Apart from emacs usage, I'm reasonably happy with using the ALT key to bring up the HUD. While using emacs though, the ALT key is tapped frequently to invoke commands. Should emacs be special cased with respect to the ALT key? I'm wondering what the situation is with games; surely lots of games repurpose the ALT key for their own use, e.g. to fire a weapon? If so, could the same be applied to Emacs, i.e. prevent the ALT key in emacs from triggering the HUD. Edit: just realized how extensively I use the ALT key in the terminal: a quick tap of ALT+B to move back a word loses focus of the terminal and brings up the HUD. Aghch

• Different behavior when launched from terminal instead of Unity launcher

  - by dgkontopoulos

  I have written two Perl/Gtk programs. When launched from the dash menu, they run just fine. However, if I try to launch them from terminal using the very same command found in their .desktop files, their Unity launcher will be blurry and will remain inactive when clicked, if I keep it in the Unity bar. The problem is solved if the Exec part of the desktop file is replaced with perl path_to_script However, that leads to other problems, including a lintian warning and forcing all Perl GUI applications running from terminal to adopt the same launcher. This issue is quite annoying since one of the programs relies on a different (Python) program in order to be launched and this results in having a blurry and inactive launcher.

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

• Cocos2D Terminal Application

  - by Hasyimi Bahrudin

  Is it possible to create a terminal application which uses cocos2d? I've tried to make one using cocos2d 2.x, but it requires a MacGLView to be initialized. I need it so that I could program a terminal application that generates a screenshot given a TMX file and an optional preferred width or height parameter (for resizing). Then I can automate the generation of map previews for my game, instead of manually taking screenshots. It's not practical to load the actual TMX and resize it inside the game (what I'm currently doing), because each TMX file has 7 layers, my tile sheet is huge, and I have lots of levels.

• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

• How to find out where alias (in the bash sense) is defined when running Terminal in Mac OS X

  - by Richard Fuhr

  How can I find out where an alias is defined on my system? I am referring to the kind of alias that is used within a Terminal session launched from Mac OS X (10.6.3). For example, if I enter the alias command with no parameters at a Terminal command prompt, I get a list of aliases that I have set, for example, this is one of them alias mysql='/usr/local/mysql/bin/mysql' However, I have searched all over my system using Spotlight and mdfind in various startup files and so far can not find where this alias has been defined ( I did it a long time ago and didn't write down where I assigned the alias).

• How do I write to a file and print to a terminal cuncurrently in Unix?

  - by bias

  I have a little bash function to log my Macports outputs to a file (since installs often spew little tidbits that are easy to lose in terminal noise), then I just cat the file to the terminal: function porti { command sudo port install $@ >> $1.log 2>&1; cat $1.log } Is there a way to do this concurrently? I don't care about it being in Bash, that's just how I started it. BTW I pass $@ to install but only $1 for the file name so that I can do something like: porti git-gore +bash_completion and only get the file git-core.log however someone else might prefer to include variants in the file name ...

• Adding icon to gcc executable and opening in terminal.

I want to have the executable with an icon so that a user can click on the executable and the program starts in the terminal. How do I add an icon to the executable and start the program in the terminal? Sorry I failed to mention before that its in Ubuntu Linux

• How to launch a mac application without a terminal window.

  - by KPexEA

  I've written an open-source c++ application and it works fine on Windows and Linux, I finally got a Mac Mini (with 10.5.8) so I've just been testing the Mac version. My application works fine when running it from inside a terminal window and typing ./appname , but if instead I double click on it from the finder, then it opens a termnial window first and then runs my app but it doesn't seem to set the working directory to the correct location so my app dies. How do I make my app so when it launches by being double clicked on it doesn't open a terminal window first and how can I have the current directory set to the apps location automatically?

• cd Terminal at a given directory after running a Python script?

  - by Dave Everitt

  I'm working on a simple Python script that can use subprocess and/or os to execute some commands, which is working fine. However, when the script exits I'd like to cd the actual Terminal (in this case OS X) so on exit, the new files are ready to use in the directory where the have been created. All the following (subprocess.Popen, os.system, os.chdir) can do what I want from within the script (i.e. they execute stuff in the target directory) but on exit leave the Terminal at the script's own directory, not the target directory. I'd like to avoid writing a shell script to temporary file just to achieve this, if this is at all possible anyway?

• What are the default layout settings in gnome-terminal?

  - by Exeleration-G

  I want to replace gnome-terminal fully by lxterminal. I've started by changing the default terminal emulator. So I ran sudo update-alternatives --config x-terminal-emulator, and chose lxterminal. After that, I ran dconf-editor and went to org - gnome - desktop - applications - terminal and changed gnome-terminal to lxterminal and removed the -x in the exec arg part. The only problem though, is that by default, lxterminal doesn't look like gnome-terminal. What are gnome-terminal's default layout settings? I'm especially looking for the hexadecimal colour codes for both text and background.

• Colorizing your terminal and shell environment?

  - by Stefan Lasiewski

  I spend most of my time working in Unix environments and using Terminal emulators. I try to use color on the commandline, because color makes the output more useful and intuitive. What are some good ways to add color to my terminal environment? What tricks do you do? What pitfals have you encountered? Unfortunately, support for color is wildly variable depending on terminal type, OS, TERM setting, utility, buggy implementations, etc. Here's what I do currently, after alot of experimentation: I tend to set 'TERM=xterm-color', which is supported on most hosts (but not all). I work on a number of different hosts, different OS versions, etc. I'm trying to keep things simple and generic, if possible. Many OSs set things like 'dircolors' and by default, and I don't want to modify this everywhere. So I try to stick with the defaults. Instead tweak my Terminal's color configuration. Use color for some unix commands (ls, grep, less, vim) and the Bash prompt. These commands seem to the standard "ANSI escape sequences" I've managed to find some settings which are widely supported, and which don't print gobbledygook characters in older environments (even FreeBSD4!) (For the most part). From my .bash_profile ### Color support # The Terminal application typically does 'export TERM=term=color' # Some terminal types will print Black, White & underlined with these settings. OS=`uname -s` case "$OS" in "SunOS" ) # Solaris9 ls doesn't allow color, so use special characters instead. LS_OPTS='-F' ;; "Linux" ) # GNU tools supports colors! See dircolors to customize colors export LS_OPTS='--color=auto' # Color support using 'less -R' alias less='less --RAW-CONTROL-CHARS' alias ls='ls ${LS_OPTS} export GREP_OPTIONS="--color=auto" ;; "Darwin"|"FreeBSD") # Most FreeBSD & Apple Darwin supports colors # LS_OPTS="-G" export CLICOLOR=true alias less='less --RAW-CONTROL-CHARS' export GREP_OPTIONS="--color=auto" ;; esac

• Is having a [high-end] video card important on a server?

  - by Patrick

  My application is quite interactive application with lots of colors and drag-and-drop functionality, but no fancy 3D-stuff or animations or video, so I only used plain GDI (no GDI Plus, No DirectX). In the past my applications ran in desktops or laptops, and I suggested my customers to invest in a decent video card, with: a minimum resolution of 1280x1024 a minimum color depth of 24 pixels X Megabytes of memory on the video card Now my users are switching more and more to terminal servers, therefore my question: What is the importance of a video card on a terminal server? Is a video card needed anyway on the terminal server? If it is, is the resolution of the remote desktop client limited to the resolutions supported by the video card on the server? Can the choice of a video card in the server influence the performance of the applications running on the terminal server (but shown on a desktop PC)? If I start to make use of graphical libraries (like Qt) or things like DirectX, will this then have an influence on the choice of video card on the terminal server? Are calculations in that case 'offloaded' to the video card? Even on the terminal server? Thanks.

• Printing on Remote Desktop session

  - by Arindam Banerjee

  We have to connect a Windows 2008 server using Remote Desktop from Windows XP machine. A Barcode Printer is attached with XP machine and the printer is shared as Local Resource in RDC session to the server. On the server we have to print from an application which prints either to LPT port or shared printer (UNC path). For this I use to configure print pooling combining LPT1 and (Terminal Server) TSxxx port. As I don't know the option to access the Terminal Session printer via UNC path. But I have the following issues - Every time I connect to a remote session, the printer from my local Win XP machine is showing in Printers and Faxes on Win 2008 Server (Terminal Server), but I am not allowed to manage the Win XP printer from Terminal Server to enable pooling. On the server I have to change the security permission every time and then enable print pooling. How can I keep the security permission unchanged? Secondly I created a batch file to enable print pooling. rundll32 printui.dll,PrintUIEntry /Xs /n "Printer (from CLIENT)" Portname "LPT1:,TS005" But every time the printer in terminal session connects in diffrent terminal Session port. Any solution to make the TS port fixed? Help from anyone will be highly appreciated.
