Setting environment variables: bash issue

travonz · July 30, 2012, 04:29

Hello,

I would like to automate environment initialization prior to OpenFOAM use.
I wrote the following bash script, but it doesn't work at all. Environment is only set inside script, when it exit the script and goes back to console, nothing changes, no variable has been defined.

#!/bin/bash
source /opt/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc
source $HOME/.bashrc
cd $FOAM_RUN

Do you know how can I keep environment after script execution ?

Thanks for your help.

Xavier

Greetings Xavier and welcome to the forum!

You should resort to an alias instead, placed in your "~/.bashrc". Example for your case:

Code:

alias of211combo='source /opt/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc; cd $FOAM_RUN'
