In order to modify my paths (like LD_LIBRARY_PATH or PYTHONPATH), I first check is the variable exists. If so, I'm concatenating my old value with the new one (separated with a semicolon), else I'm settings my variable to the new value.
NEW_PATH='/path/to/new/path'
if [ $LD_LIBRARY_PATH ]
then
export LD_LIBRARY_PATH=$NEW_PATH:$LD_LIBRARY_PATH
else
export LD_LIBRARY_PATH=$NEW_PATH
fi
It works, but it is a bit clumsy when you have lot of these in script to source : is there a clever trick to make this block a nice one liner ?
Thanks !
