How to set environment variable in bash profile in linux

Solution

no space in between!

when setting environment variable in bash profile, VERY IMPORTANT DON’T PUT space in between anything. There should be no space like

env_var=blah, not env_var = blah.

For example,

Export LD_LIBRARY_PATH=${LD_LIBRARY}:/home/brian/bitch
Export JAVA_HOME=/home/brian/jdk/jdk1.8.0_371
Export PATH=$JAVA_HOME/bin:$PATH

Wrong:

Export LD_LIBRARY_PATH  =  ${LD_LIBRARY}:/home/brian/bitch
#Notice the space in between var and = 

don’t forget to save your changes!

Once you have set environments you want to save it via

vi .bash_profile 
#and to set the changes, 
source .bash_profile
