I just started learning Scripting in Shell Script, RHEL 6.3

This question already has an answer here:

Check if a directory exists in a shell script 32 answers

---

The simplest technique is to use mkdir -p which creates the directory — and any missing directories up the path — and does not fail if the directory already exists, so you can do it all at once with:

mkdir -p "$LOCAL_WORKING_DIR" "$LOCAL_EVENT_LOG_WORKING_DIR"

Note that the variables are enclosed in double quotes so that even if spaces (etc.) appear in the name, it will work sanely.
