When installing multiple agent on the same UNIX box, only one starts, the other are getting:
WAAE Agent Already running (pid xxxxx) FAILED

Instead of taking the PWD environment variable, that is common to all agents, the script will actually execute the unix pwd command and take the correct directory. Multiple agents can then coexist.
