How to expand relative paths in shell script

Question

I am writing a script to set environment variables on linux 2.6 using bash. So the script contains commands like:

export SRC_DIR=..
export LIBPATH=${SRC_DIR}/lib         


        

Answer 1

Digging up this old thread to add what i've found to work nicely:

export SRC_DIR = `realpath ..`

see more information here:
