[ubuntu] Setting environment variables before opening Xwindows

view story
linux-howto

http://ubuntuforums.org – Hi, I'm installing 12.04 on a new machine. I've been using 8.04. In 8.04 I accessed my windows manager (either gnome or fvwm) from the command line, using startx. In this setup I was able to set a number of environment variables, which were utilized in my startup script. But 12.04 boots to a GUI, which is nice, but I can't set my environment variables. Is there a way to disable the initial GUI, so that I login the old-fashioned way, and can execute scripts from the command line, then use startx? Thanks, Leo (Hardware)

Environment Variables 50 weeks 4 days ago

Hi Experts,

Need your help in understanding the commands to setup the environment variables in hp-ux.

Beleive need to use either set,setenv or export.

I am confused between above three options, when to use which option?

On command line, I have tried both set and setenv but couldn't able to set the environment variables. However with export it was working fine.

How do I set manually environment variables for metasploit, when I execute db_driver I get this message:

[*] No Active Driver [*] Available:

[*] DB Support: Enable the postgresql driver with the following command: [*] * This requires libpq-dev and a build environment [*] $ gem install postgres [*] $ gem install pg # is an alternative

From the lfs doc:

The exec env -i.../bin/bash command in the .bash_profile replaces the running shell with a new one with a completely empty environment, except for the HOME, TERM, and PS1 variables. This ensures that no unwanted and potentially hazardous environment variables from the host system leak into the build environment.

I noticed a difference in 'env' before and after a 'screen' call, is there any additional clarity on what gets called (for setting environment variables)?

I am writing a shell script, to read a file which has key=value pair and set those variables as environment variables. But I have a doubt, if I do source file.txt will that set the variables defined in that file as environment variable or I should read the file line by line and set it using export command ?

Is source command in this case different than export?

I have OpenSuse 11.4.

I start some on-boot scripts inside /etc/init/boot.local.

Where could I move those scripts so that they would be started after all (most) environment variables got initialized?

These scripts need to be started really once, so things such as /etc/profile.local aren't candidates.

I try to start Sonar, which searches for Java in some strange way (instead just by look up JAVA

In /etc/ssh/sshd_config, there is an option called AcceptEnv that allows the ssh client to send environment variables. I need to be able to send a large number of environment variables. These change on every connection from the client, so putting them in a login script on the server would be more difficult.

I've read that "AcceptEnv *" is insecure.

I have tried to get some variable through Java (System.getenv()) which was set inside ~/.bashrc It hasn't appeared in the list of variables.

Close but not quite there, that just wipes all the environment variables. Any idea how I could get the default variables for $USER from there? Thanks, BTW.
