I am using Red Hat Linux Enterprise 5. I know the theory that -- using export to set environment variable, the environment variable will apply to current and child environment, but without using export to set environment variable, the environment variable will only apply to the current environment. What is the exact definition of "child environment" and "current environment"? For example,
Code: $ var1=123 $ echo "Hello [$var1]" The value of var1 (which is 123) is printed in shell, but I think echo is a command invoked by current shell, and it (the echo command) should be a child environment of current shell and the value of var1 should not (because not using export var1=123) impact echo.
I have two keyboard layouts installed in my system and I need to determine in scripts which one I'm on. What the environment variable contains indicator of current keyboard layout?
I have been trying to change my PATH environment variable to no avail. I am using Jessie i386 with MATE. Using my .bashrc file works but not well because with subshells the modifications get repeated. I want the change to occur on login.
I tried modifying ~/.profile ~/.bash_profile /etc/profile and /etc/environment and one or two others but in no case did my change get picked up even after logging out and in again and even after rebooting. I searched the Internet and found each of the above places to make the change but they don't seem to work with Jessie.
I am a newbie to Linux. I tried setting environment variable using export JAVA_HOME=/usr/java/jdk1.6 but that was not permanent (i.e is was there for that terminal session). I want to know how can i set environment variable permanently in Fedora 13 just like we do in windows.After google search, some user suggested to edit bashrc and profile file for setting environment variables but above file contains some shell programs.
IN 3.5.10 I am able to display the full $PROMPT_COMMAND environment variable in the Konsole title bar. Kind of handy and I did not need to display that information in the $PROMPT variable.
In 4.5.5 I am having trouble figuring out how to make that work correctly. The title bar displays only the directory name rather than the full path and user name.
This is my $PROMPT_COMMAND:
history -a;echo -ne "33]0;${USER}@`uname -n`: ${PWD}07"
All I see in the title bar is:
dirname: bash
I should see:
username@hostname: full path to present working directory
I am connected to work via a VPN. I am logging into a Solaris box at work from OpenSuse 11, using ssh -X. I would like to start a GUI on the solaris box. The problem is that I don't know what value to give the DISPLAY variable. Is it the local internal LAN ip address, for my machine? I did try that, and I tested it using, xterm on the solaris machine. It says it can't open the display. I have enabled remote connections on my machine using xhost +.I have to run a performance test on the Solaris box at 7am in the morning... so need to find out how to start the GUI
I am running Fedora 9 in virtual box on laptop. Want to set Fedora display size so that I will not have to scroll up or down or sideways to view screen contents. Have tried a couple of options such a resize box and change from full size but these do not help reduce size of Fedora display. Am wondering if it as something to do with the rectangular size of laptop monitor???

I have a dedicated PC with Debian Linux and now wish to install Oracle 11gR2. All the required changes and settings were made as per Oracle Pre-Install.
When I start the installer it errors out almost immediately due to a display problem as it it verifying if the display can accommodate 256 colours. The /etc/hosts file has a setting: 127.0.0.1 localhost so I set the DISPLAY=localhost:0.0
I am supposed to create an environment variable with the PRINTER variable, which should resolve to the word sales. Would the command be like this?: env PRINTER - NAME=SALES (is this the command to create that variable with resolving the word sales to it?)
I've AMD64 system with Ubuntu 11.04 installed. It's been rough ride for me to install oracle-xe-universal. I've already spent more than 2 days on this. Still unsuccessful.
1) First I downloaded the packages libaio_0.3.104-1_i386.deb and oracle-xe-universal_10.2.0.1-1.1_i386.deb
(gave me dependency error for libc6 (>= 2.3.2), I modified the control file to remove dependency and rebuilt the package) (now worked fine) Oracle xe is now installed. Then I tried to start the DB it started but it's HTTP client never started. So I decided to uninstall the oracle-xe=universal. None of the sudo apt-get remove oracle-xe-universal command's didn't worked for me. So i went for manual uninstallation directions as per oracle link.
rocky@ubuntu:~/git/mygit/edas2/libaio$ sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb dpkg: warning: overriding problem because --force enabled: package architecture (i386) does not match system (amd64)
[code]....
Even in applications menu I don't see the if oracle has been installed. So i conclude first time installation was ok but somehow http client didn't worked. After manual uninstallation, second installation didn't even loaded/installed the oracle-xe in init.d directory.
I am attempting to add a user via the adduser command. However, I get an error/warning message after entering the following: (note I am following a HOWTO, and this is the line it says to enter).

This is a laptop, to which I connect an external hdmi display when I get to work. dipser -e extends the desktop for me, but the laptop remains the primary desktop (holding the panels etc). nvidia-settings can set primary monitor for me, but I want to use the cli.

Installed 11.3 KDE today on an old Vaio desktop we were given (Duron 900Mhz, 512mb, 40Gb HD, SiS630 onboard video, Trinitron 15" monitor). Everything works fine except it will not save the 800x600 resolution setting. Every time I reboot it is back to 1280x1024 which it thinks is the default resolution. Any tweak to get 11.3 to save that setting?
I'm trying to add 2 new environment variables (Debian . I have created a "/etc/profile.d/java.sh" file and in it I have added these lines (and just for the record, I've also tried adding those line to the profile file with the same results as explained below).
The first variable "XAPPLRESDIR" is added just fine (I check by doing echo $XAPPLRESDIR). The second variable is not added. Here's what I discovered though, if I change the variable name to LD_LIBRARY_PATK (I change the word "path" into something else) then it works just fine... So how am I supposed to add this variable? I need it to be named just that...

I'm setting my CLASSPATH in /etc/profile.d/jre.sh. In a login shelleverything is fine. In an xterm window, the CLASSPATH consists of two of every intended entry.In jre.sh I am doing aCode:export CLASSPATH=$CLASSPATH:/many/paths/to/jarsSo I'm guessing this is getting run twice in the xterm case. Can someone explain what's going on here and what I should do to remedy this?
I'm trying to configure subclipse with JAVAHL for ganymede. I have everything installed and the right version of the JAVAHL.
I have seen that a lot of people uses java.library.path in the eclipse.ini file to set it up or just write a script for launching eclipse.
