Slackware :: Setting The JAVA_HOME Variable ?

Jan 10, 2009

I have problems with setting my JAVA_HOME variable. I am using Slackware 12.0, bash shell. This is a question for the 'Linux Newbie' forum (not slackware-specific).

I have set JAVA_HOME in my /etc/profile, like this:

But when I login in with my user name and type env on the command line, I get for JAVA_HOME the following:

Also, in my /etc/profile I have put the path to my java in the PATH variable, like this:

And when I type env when I login, then the PATH variable contains correctly the path to the jdk (as I have put it into /etc/profile).

I expect that after I have set everything as I want in /etc/profile, and restart the computer then what I have set will be relevant and when I login and type env, I will get values to the variables equal to those I have set in /etc/profile. Why it does not happen?

I have particularly a problem with a Java application, which I want to run. When I type ant, I get:
error: JAVA_HOME is not defined correctly. We cannot execute /usr/lib/java/bin/java.

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.

General :: Setting JAVA_HOME In .bash_profile Doesn't Work

Apr 15, 2009

I have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile

Code:
PATH=$PATH:$HOME/bin
PATH=/usr/java/jdk1.5.0_16/bin:$PATH
JAVA_HOME=/usr/java/jdk1.5.0_16/
export PATH JAVA_HOME

Debian :: Setting PATH Environment Variable

May 19, 2015

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.

Where do I make the necessary change?

OpenSUSE Network :: DISPLAY Variable Setting Over VPN?

Jun 9, 2010

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

General :: (standard_in) 1: Parse Error Setting Variable With Bc?

Jul 19, 2011

I'm trying to define a variable, CHAN, by dividing another variable, FREQ, by a number. FREQ is a value from a file (called header.txt). What I think I'm doing with this bit of code is reading a number from header.txt whose location is specified by the head and tails, assigning it to FREQ and then defining CHAN with bc.

Code:

Slackware :: Environment Variable Being Set Twice?

Jul 25, 2010

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?

Slackware :: Using A $variable With Find -name?

Jan 30, 2010

Here is my example code that doesn't work:

find $HOME -type d -name "$WHATEVER" -exec rm -rfv {} ';'

$HOME works ofcourse. it's $WHATEVER that -name doesn't honor. Has to be a variable. I really don't see a way around it because $WHATEVER could be any number of things depending on the circumstance. I've also tried other things:

find $HOME -type d -name '${WHATEVER}' -exec rm -rfv {} ';'

Using backticks will process $WHATEVER but it tries to execute it as a command instead of processing it as an argument to -name....

Slackware :: Change The $ARCH Variable To X86_64 Too, Right?

I'm mainly asking beforehand so I won't have to shoot myself in the head twenty minutes from now. I suppose I'll find/figure out one way or the other anyway . Can I just source the 32dev.sh and then run sbopkg -i if the source for the package I want to create isn't 64bit capable? I might need to change the $ARCH variable to x86_64 too, right?

Slackware :: Tcsh - Unknown Colorls Variable 'ca'

Jul 27, 2010

I have been using tcsh for quite some time, both on a laptop running Ubuntu and a remote server running Slackware 11. No problem whatsoever. Now I am compiling and installing tcsh on a brand new Slackware 13 box and when I run tcsh I get this error:

Unknown colorls variable 'ca'

or

Unknown colorls variable 'hl'

I didn't have this problem in Slackware 11, why is it happening now?

So I tried the official Slackware package for tcsh. It works, but it's tcsh 6.15.00. Tcsh is at 6.17.00, which runs fine on my Slackware 11 box.

I investigated the problem on Google and all reports seem to refer to Fedora, some to Mandriva. Many of the threads, across several forums and sites, point to this LinuxQuestions thread:

Slackware :: Display The Full $PROMPT_COMMAND Environment Variable In The Konsole Title Bar?

Mar 18, 2011

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
