View 3 Replies View RelatedI always have to google about setting environment path variables when I install new software. My basic problem is that I dont know whether these variables need to be set globally or not. I have read a number of mails/tutorials which say that Environment variables should be set by simply doing an export ..eg EDITOR=nano export EDITOR
additionally I have read that it should be written into /etc/bash.bashrc
But are these really global variables or local? I want the variables to be set
even after I have logged out.
so I could also write the variable here...
/etc/environment
or here
/etc/profile
I want to make change to environment PATH system wide. Because I have program called "md5". I want to execute it from anywhere (i.e any directory).
My md5 program is located at "/home/ahuq/MappingServer/md5_program". So what I did was to put: "export PATH=$PATH:/home/ahuq/MappingServer/md5_program" in the running SHELL.
This only makes temporary changes and lets me run the "md5" program from anywhere temporarily.
But I want to make this change permanent. So what I did was to put the "PATH=$PATH:/home/ahuq/MappingServer/md5_program" line into the "/etc/environment" file.
This screwed everything up and then for a while I couldn't execute anything from SHELL. I knew the absolute path of "nano" editor and used it to modify the file (i.e. /etc/environment) back to its original condition.
This fixed the problem and now I can run programs like "ls" from the SHELL.
But still I need a way to permanently add the path of "md5" to the environment. How can I do this in Ubuntu 10.10? Which file needs to edited?
Do I just logout or do I have to restart the system to make the changes active?
I know many people have asked about environment variables before, but I am having a hard time dealing with these paths while ensuring I don't mess around with the original settings. How would you go about executing these commands in Ubuntu in terms of environment variables?

I am using Linux some years, but since I built a LFS, I feel noobish again. Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?

View 2 Replies View RelatedSometimes it is possible to trick a Linux app by calling it like this:
HOME=/tmp/foo myapp
This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~.
A similar trick can be done like this: LANG=foo LC_ALL=bar myapp
This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile.
Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.
I often need to change a small part of long environment variable (especially, e.g., paths), and do it either by pasting the thing into an editor and changing it there, or the equivalent.
Is there some small convenience utility to edit environment variables with a cursor on the command line?
I suppose I could always whip one up, but am hoping there's already something that I'm just not aware of.
I have installed RDGEN which comes with VPFIT package. When I run the program it says:
"Failed to find help file"
But I ran the program from its main directory where all the files including help files exist. I think maybe the problem is because of this that THEY say:
"Some environment variables should be set before starting RDGEN".
But I do not know what does this mean and how to do that.
These are the variables:
-ATOMDIR
-RD PRSETUP
-RD PRSETUP
-RDSTART
-VPFSETUP
-VPFPLOTS
Would it be possible for you to tell me what does Setting Variable means in this case?
Is there a way I can write a file that contains the text which assigns variables, e.g. string="hello world" in a file say, variables.txt and have a shell script assign those variables locally e.g.

echo $string
and when I run the script I would get an output of
"hello world"

View 3 Replies View RelatedI've created a new environment variable and updated another one (PATH). I just want to save this changes once after reboot and forever. This is because I want to run a program (tecplot) just typing 'tec360' in the command line. If I create those new variable ( TEC_360_2008=/usr/tec360_2008 ) and update the PATH variable ( export PATH=$PATH:$TEC_360_2008/bin ) then bash detect the command 'tec360' and it runs my program. The problem is that this changes are not saved after rebooting.

Scons quits with a KeyError message from python2.7 saying that os.environ['DEB_HOST_ARCH_OS'] is not defined.
Checking with 'dpkg-archtecture -l' shows that DEB_HOST_ARCH_OS=linux, but 'print os.environ["DEB_HOST_ARCH_OS"]' in python says that name 'os' is not defined. The scons script has 'import os' at the top so it should be seeing it.
How do I make this visible to python (I'm assuming this problem is specific to the jessie python2.7 installation and not python in general)?
