Your find line:
Don't forget \! -name Users

Otherwise, yes It would not delete JoeUser, .localized, Shared, nor $USER.

You definitely want to exclude Users, as that would get deleted if it's time stamp is older than a day. Bad, since every home folder you wanted to keep would get deleted too.

You could remove the "exit 1" line from the script so that you still get notification that your admin user account/s will not be deleted. Your first if statement would then just for the notification, proceeding on to the find and delete operation. It should look like this:

Code:

# If home directory exists, delete 
find /Users \( \! -name Users -and \! -name JoeUser -and \! -name .localized -and \! -name Shared -and \! -name $USER \) -maxdepth 1 \! -mtime -1d -exec rm -R {} \;
dscl . -delete /Users/"$USER"
exit 0

As far as creating your own goes:
Advanced Bash-Scripting Guide

Verrrry handy.

Other than that, there's a "Learn Shell Scripting in 24 Hours" which even if it takes 24 days still isn't bad. Also web search, maybe even a quick and dirty Unix class at a local Community College?

It should be said that there is usually more than one way to accomplish the same task. Some might make use almost exclusively of awk, while others might never get much outside of python. Still others might scoff at not using ruby.

I've found that these Unix forums provide real examples of tasks one might need to perform, particularly Shell Programming and Scripting, Unix for Dummies... and Unix for Advanced. I have spent a few hours since finding these forums trying code out to see what it does. If the commands are not exclusive to a particular version of Unix, then it will be informative.
I find shell scripting (bash and/or sh) to be adequate, if admittedly sometimes clunky, for my needs. Learning something else is almost always limited to finding I cannot complete the task in the shell by itself. My most recent tenuous forays into the unknown have been simple awk line parsing with it's marvelous print function.
Pretty darned rare, but then I'm a simple kinda guy.

rmm

RMM(1)								     [nmh-1.5]								    RMM(1)

NAME

       rmm - remove messages

SYNOPSIS

       rmm [+folder] [msgs] [-unlink | -nounlink] [-version] [-help]

DESCRIPTION

       By  default,  rmm  will remove the specified messages by renaming each of the message files with a site-dependent prefix (usually a comma).
       Such files will then need to be removed in some manner after a certain amount of time.  Many sites arrange for cron to remove  these  files
       once a day, so check with your system administrator.

       Alternately,  if  you  wish  for  rmm to really remove the files representing these messages, you can use the -unlink switch.  But messages
       removed by this method cannot be later recovered.

       If you prefer a more sophisticated method of `removing' messages, you can define the rmmproc profile component.	For example, you can add a
       profile component such as

	    rmmproc:  /home/foouser/bin/rmm_msgs

       then instead of simply renaming the message file, rmm will call the named program or script to handle the files that represent the messages
       to be deleted.

       Some users of csh prefer the following:

	    alias rmm 'refile +d'

       where folder `+d' is a folder for deleted messages, and

	    alias mexp 'rm `mhpath +d all`'

       is used to "expunge" deleted messages.

       The current message is not changed by rmm, so a next
	will advance to the next message in the folder as expected.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder
       rmmproc: 	    Program to delete the message

SEE ALSO

       refile(1), rmf(1)

DEFAULTS

       `+folder' defaults to the current folder
       `msgs' defaults to cur
       `-nounlink'

CONTEXT

       If a folder is given, it will become the current folder.

BUGS

       Since refile uses your rmmproc to delete the message, the rmmproc must NOT call refile without specifying -normmproc, or you will create an
       infinte loop.

MH.6.8								   11 June 2012 							    RMM(1)
