How do I set a permanent environment variable (i.e. one that does not need exporting every time I start a new Terminal session) in Mac OS X 10.9? I've found a number of answers about modifying my .bash_profile and .profile, however neither of these options seem to work as permanent solutions - only temporary. The variable I'm trying to set is MULE_HOME. I have the following line in my bash profile:

export MULE_HOME=$(/opt/mule-standalone-3.4.0)

However, when I start Terminal I get the following line (not sure if this is normal behaviour?):

-bash: /opt/mule-standalone-3.4.0: is a directory

And running a simple env command returns the following:

TERM_PROGRAM=Apple_Terminal
SHELL=/bin/bash
TERM=xterm-256color
TMPDIR=/var/folders/fc/68bqp4jj411gynj5qvwhq6z1shs1fy/T/
Apple_PubSub_Socket_Render=/tmp/launch-xKtkql/Render
TERM_PROGRAM_VERSION=326
TERM_SESSION_ID=E97BFE4B-AF85-4933-B252-0883CC085349
USER=dan
SSH_AUTH_SOCK=/tmp/launch-rEmTWW/Listeners
__CF_USER_TEXT_ENCODING=0x730C85DE:0:0
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
__CHECKFIX1436934=1
PWD=/Users/dan
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
LANG=en_GB.UTF-8
MULE_HOME=
SHLVL=1
HOME=/Users/dan
LOGNAME=danwiseman
_=/usr/bin/env

In order to get around this I'm currently having to type export MULE_HOME=/opt/mule-standalone-3.4.0 every time I start a new Terminal session which, whilst not strenuous, is a little inconvenient. What am I doing wrong here that is causing the variable to only be set temporarily? Thanks in advance.

Just did this really easy and quick. First create a ~/.bash_profile from terminal:

touch ~/.bash_profile

then

open -a TextEdit.app ~/.bash_profile

add

export TOMCAT_HOME=/Library/Tomcat/Home

Save document in TextEdit and you are done.
