Scripting Tips

•use consistant naming/styling •comment...at very least intital comment(s) •quote or backslash commands in scripts to be more portable.  Otherwise aliases in your environment will be picked up by your scripts.
•second line of your scripts should be "#set -x"...for debugging un/comment as needed
•wrap variable name references in "${}"
•use "$(command)" instead of "`command`"...easier to read and debug
