Examples of org.rhq.enterprise.agent.EnvironmentScriptFileUpdate

org.rhq.enterprise.agent.EnvironmentScriptFileUpdate
This utility helps update one or more environment script files without losing the ordering of existing variables or comment lines. An "environment script" is a script file that simply contains lines that set environment variables (i.e. "RHQ_AGENT_MY_VAR=some.value" or "set NAME=VALUE" for Windows scripts).
You can update changes to existing environment variables or add new ones.

Note that this utility only works on simple environment script files where each name=value pair exists on single lines (i.e. they do not span multiple lines). But it can handle commented lines (i.e. comments are preserved).
