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.

Can u tell the error for me , if [ ! -d "$LOCAL_WORKING_DIR" ] then mkdir "$LOCAL_WORKING_DIR" cd "$LOCAL_WORKING_DIR" else cd"$LOCAL_WORKING_DIR" fi
Please don't put code in comments; you can't control the formatting. If you do, you have to be careful to make sure it will work despite the absence of formatting. What I can see has no semicolons, but semicolons would be necessary if it is all on one line. Edit your question. (The cd "$LOCAL_WORKING_DIR" should be after the if since you change to it regardless. The second one also needs a space between cd and "$LOCAL_WORKING_DIR".)
