I am new in Using Ubuntu, I need to set up environmental variables in Ubuntu, I do the following:
Code:
export JAVA_HOME=/path/to/Java
export PATH=$JAVA_HOME:$PATH
it work fine, but every time I restart the system I have to reset it again Is that the right way to it, or I do something wrong
I have installed ubuntu10.04 LTS in VirtualBox in my home computer(i forgot to tell you i am very new to linux-though i am studying a lot, but....-maybe because of my age "45" i am going slow. LOL. I hope i dont have a heart attack before i finish what i am trying to do in the server). Back to my issue: What i want is to have in the server some enviromental variables running not only for the root user but for all the users,when the server is open and not having to type the following commands every single time i open the terminal. Here are the commands:
export JAVA_HOME=/opt/java
export PATH=$JAVA_HOME/bin:$PATH
export M2_HOME=/opt/maven/maven
export PATH=$M2_HOME/bin:$PATH
[code]....
(where java, maven, tomcat are symbolic links for java jdk, maven and apache-tomcat 5.5.31). Please (LOL) save me from the heart attack, give me the chance to enjoy the holidays with my family!
I installed Java on a server and anytime I have to start or stop a service that requires the $JAVA_HOME variable I have to manually set it with the export command such as: Code: export JAVA_HOME=/usr/java-jdk1.6.0_21 How can I permanently set this variable?
View 3 Replies View RelatedFor example, if I'm in csh, I can use `setenv VARNAME varVALUE` while I can use export in Bash. Given that the environmental variables are created, can BASH read env vars from csh and vice versa?
View 2 Replies View RelatedMy question has to do with how environmental variables are passed from parent to child processes at the BASH SOURCE CODE level. I have a need to add an environmental variable that has the complete invocation line so that the child process can see it via ENVP.I have been studying the source for a quite a while and can't seem to find how to make the variable pass to the child. In EXECUTE_CMD.c I found a good place to set the variable: I made a routine similar to PUT_COMMAND_NAME_INTO_ENV called PUT_COMMAND_LINE_INTO_ENV which would add "?=THE FULL INVOCATION LINE" as an environmental variable but it doesn't make it to the child. (I've tried names other than '?' but they don't work either.
I'm thinking that there is either a LIST or a attribute associated with those environmental variables that should be passed to the child but I can't find it.

Basically, when I do a reboot or shutdown and then the system tries to start I get a blank screen thus I have to hit the reset button and then I'm showed a grub menu (not sure why I have it set to autoboot) and then I can boot properly.
In my KUBUNTU 9.04 every time i set my desktop(wallpaper) it is reset to default after restart.

I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)
"name@name-desktop:...$ "

It is an hp compaq d220 MT.It looks good and feels good, well at least for a while since it keeps crashing. The screen starts to flicker, goes black, and the only way to get it up and running again is to press the on/off button until the system powers off and restart.
View 2 Replies View RelatedI'm trying to use system to call echo and pass variables to it. That was a success. The problem is the variables inside the while-loop i wrote cannot be manipulated. what I'm doing wrong here? here's the code:
Code:
#include <iostream>
#include <stdlib.h>
#include <string>
#include <sstream>
[Code]....
mkvmerge -o <filename without extension>_TV.mkv -S <filename> && mkvextract tracks <filename> 3:<filename without extension>.*** && perl /home/brian/Desktop/ass2srt.pl <filename without extension>.*** && rm <filename without extension>.***
Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.
I need to include variables in a system() call. This is that I have:
[code]#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

P.S.: I know this is a pointless redundant program, but it's part of a larger project learning process.
I just recently reinstalled openSUSE 11.3 last night with the GNOME desktop. Since I'm starting fresh again, I'd like to set up my System as flawless as possible.
So, my question is stated in the Title. How do you set System-Wide environment variables on OpenSUSE 11.3 // GNOME? I usually set them by adding an export to my ~/.bashrc, but I remember in Ubuntu that I could add them to /etc/environment. I checked that file out on my system, and it has a the default comment on it stating:
"This file is parsed by pam_env module...Syntax: simple "KEY=VAL" pairs on seperate lines"
This seems to be the spot to add my "export JAVA_HOME=/usr/java/..etc", etc. but I wanted to clarify before I went ahead and made any changes.
I have an RHEL 5 server joined to a windows domain. However I wanted to add variable lines to be executed each time a user logs in. However I succeeded to put them in /etc/bashrc file and it worked like a charm.
But its annoying that everytime the user logs in to the shell remotely it displays the whole variables that were declared. Is there a way how to add them once and not to display the output each time the user logs in?
I've been looking at possible options - I might install new from the CD if I have to. But before I do that, I'm wondering if there's anything I can do to restore the system to the way it would have been if I'd actually done a clean install - but to leave /home intact and perhaps the application also. (I haven't installed that many). I'm running 9.10, upgraded from 8.04>8.10>9.04 - it's working but There are some issues I can't seem to resolve such as stuttering audio.

When these users try to use the up and down arrows to view shell history they get junk characters. I checked and there is no history file in their homes. Where is the environmental variable set and how can I get this working?

View 1 Replies View RelatedI'm new to Linux, tried Ubuntu, had slow boot problems, tried openSUSE 11.1, still have slow boot problems. The issue seems to be that the ata.0 device is slow to respond (ERROR= -16), the boot system forces a hard reset, then a soft reset, configures for UDMA 133, says the drive is ready, then does it again, three times, and then configures the drive for UDMA 100. It's a brand new Western Digital Caviar drive, and windowsXP likes it just fine. Once SUSE boots, everything seems to work just fine. I thought the problem might be with the drive jumpers, so I reset them from cable detect to master/single. No change in the problem.
