Greetings, and welcome!

This is not a forum for Hackers so if that is your purpose, it is pointless to post here, you will be banned very shortly...

You mention you are in the process of developing a utility, fine only we cant help you not knowing what is its purpose, from what I understand its a shell script, as such there are no true standards, as you are free to implement whatever the way you want, it gets more tricky if the idea is that it should have a natural UNIX feeling, in such case look how the different vendors implement their stuff and find a suitable compromise, knowing there are rules on man pages ( 1: users, 1M: system administration etc...)

For the rest, up to you but the main point is more you make things complex more you suffer to maintain and update, using ordinary good coding practice and keeping up the documentation in the script is essential, 4-5 undocumented modifications, and suddenly you fall on a side effect bug, you will spend quite some time to figure out what is going on...

We are always ready and interested to see what people are capable to achieve in shell scripts only the rules here are :

- You explain your goals
- You show ( code) what you have done so far, if with issues then with error output
- When someone corrects or give you some code, you test it and give us some feedback
- You accept to be open-minded as, see first rules, depending of your level of understanding and knowledge, you may see some here have quite some imagination.. and you will have many different solutions to your aims, and the best way to learn is to test them all and ask for what you don't understand in the code, or procedure, as we all have different background our ways of resolving depends of our experience...

So the is not much more to say until we know a bit more about your project...

mc-tool

MC-TOOL(1)							     Utilities								MC-TOOL(1)

NAME

       mc-tool - manipulate Mission Control accounts from the command line

SYNOPSIS

       mc-tool list

       mc-tool add PROFILE DISPLAY-NAME [PARAMETER-SETTINGS...]

       mc-tool add MANAGER/PROTOCOL [PARAMETER-SETTINGS...]

       mc-tool update ACCOUNT [PARAMETER-SETTINGS...]

       mc-tool display ACCOUNT DISPLAY-NAME

       mc-tool nick ACCOUNT NICKNAME

       mc-tool icon ACCOUNT ICON

       mc-tool show ACCOUNT

       mc-tool get ACCOUNT PARAMETER [PARAMETER...]

       mc-tool auto-presence ACCOUNT STATUS [MESSAGE]

       mc-tool request ACCOUNT STATUS [MESSAGE]

       mc-tool auto-connect ACCOUNT on|off

       mc-tool remove ACCOUNT

DESCRIPTION

       mc-tool's usage depends on its first argument (the "command")

   SPECIFYING ACCOUNTS
       Where an account name is needed, it may be given as a full object path (e.g.  /org/freedesktop/Telepathy/Account/gabble/jabber/example), or
       as the unique account-specific suffix (e.g.  gabble/jabber/example).

   SPECIFYING PARAMETER SETTINGS
       Many commands take arguments that represent Telepathy connection manager parameters (see the Telepathy Specification for details of these).
       Each argument has the following form:

       TYPE:NAME=VALUE

       where  TYPE  is either int, uint, bool, or string (other parameter types exist, but are currently unsupported by mc-tool), NAME is the name
       of the connection manager parameter (e.g.  account or password), and VALUE is the parameter's value (with integers in decimal, and booleans
       as 0 or 1).

       The update command also accepts arguments of the form clear:NAME which delete the named parameter from the account configuration.

   LIST
       mc-tool list lists the available accounts.

   ADD
       mc-tool	add  adds  an  account.  The  connection  manager and protocol can either be given as the name of a Mission Control profile, (e.g.
       gtalk), or as a slash-separated connection manager name and protocol (e.g.  gabble/jabber).

   DISPLAY
       mc-tool display ACCOUNT DISPLAY-NAME sets the DisplayName property of ACCOUNT to DISPLAY-NAME.

   NICK
       mc-tool nick ACCOUNT NICKNAME sets the Nickname property of ACCOUNT to NICKNAME.

   ICON
       mc-tool icon ACCOUNT ICON sets the Icon property of ACCOUNT to ICON.

   SHOW
       mc-tool show ACCOUNT shows information about ACCOUNT.

   GET
       mc-tool get ACCOUNT PARAMETER [PARAMETER...]  shows the values of the given parameters of ACCOUNT.

   ENABLE
       mc-tool enable ACCOUNT sets the Enabled property of ACCOUNT to True.

   DISABLE
       mc-tool disable ACCOUNT sets the Enabled property of ACCOUNT to False.

   AUTO-PRESENCE
       mc-tool auto-presence ACCOUNT STATUS [MESSAGE] sets the AutomaticPresence property of ACCOUNT to STATUS with optional message MESSAGE.

   REQUEST
       mc-tool request ACCOUNT STATUS [MESSAGE] sets the RequestedPresence property of ACCOUNT to STATUS with optional message	MESSAGE;  this	is
       how you tell an account to connect or go offline, for example.

   AUTO-CONNECT
       mc-tool	auto-connect  ACCOUNT  on  sets the ConnectAutomatically property of ACCOUNT to True.  mc-tool auto-connect ACCOUNT off sets it to
       False.
