I'm hoping someone can tell me how to extend the scope of an exported function in the korn shell.
I have written a function in a file that I dot in from my .kshrc file and it works fine.
However I would like this function to be available to anyone in a certain group on the machine without all of them being required to dot it in, in their own .kshrc files.
Variables Used by Shell
The following variables are used by the shell:
........
........
FPATH The search path for function definitions. By default,
the FPATH directories are searched after the PATH
variable. If an executable file is found, then it is
read and executed in the current environment. FPATH is
searched before PATH when a function with the -u
attribute is referenced. The preset alias autoload
causes a function with the -u attribute to be created.
By putting the function definition in /etc/profile (or something like), you'll make it system-wide.
If you just want to make it available from a specific group then make an executable script file of it with the appropriate name and starting with the #!ksh shebang.
Do a chown root:<your group> and chmod 754 (or 750) so it will only be executable by root or members of <your group>.
Put it i.e. in /usr/local/bin , it's a good place place for it.
Unfortunately they don't tell me how to make this available to a group.
I know how to dot in the function within my shell and also how to set the FPATH and so on but these all require potential users to add an entry to their profile or kshrc file. I just thought it would be nicer if any member of a group running ksh could automatically have this available when starting a shell.
I was hoping it might be possible to call a script when a group member starts a session but I don't know if I can.
I think this would still involve an entry in their profile or kshrc though.
I think I'll start another more detailed post about what I am trying to achieve.
Thanks for the input

Now I have the package installing this how I want I can put a lot more detail in here about what I am trying to do: -
I have a two related utilities called push and pop that I have written as exported functions. They allow me to create "stacks" of directories that are presented to the user in the form of menus: -
=============================================================
Current stack is - Packaging
=============================================================
1) /home/brad/spideroak/wip/packaging/pushpop
2) /home/brad/spideroak/wip/packaging/pushpop/debian/DEBIAN
3) /home/brad/spideroak/wip/packaging/pushpop/debian/usr/bin
4) /home/brad/spideroak/wip/packaging/pushpop/debian/usr/share/doc/pushpop
5) /var/cache/man
6) /home/brad/spideroak/wip/man/man1
7) Quit
Please select a directory -
So while I am developing something I can create a stack of all of the directories I am interested in while the development is in progress. Also if I come back to it in a months time I can reload the saved stack and I can immediately see all of the directories that relate to this project.
I thought this would be a nice project to cut my teeth on debian packaging and so I have created a package that installs the files containing the functions and environment vars into /usr/bin and adds a couple of man pages.
To access the functions I put two entries into my kshrc file: -
. /usr/bin/.pp.env
. /usr/bin/.exported.funcs
I think this is the weakness in the package though, I don't like the idea of the end users needing the knowledge of how to do this. I would like the package to take care of all dependencies.
I can't have the package modify everyones kshrc or profile. After all this is specific to korn shell users and anyway people should have the right to opt in rather than have this forced on them.
That is why I was asking about the group idea but am open to any suggestions that allow users to opt in without knowing how to find and edit their profile or kshrc.
I guess in a worst case scenario I could put details on how to enter these in the man pages.
Any ideas greatly appreciated.

Hi Folks
I've been boning up on how to create debian packages and now have a working package. I am still getting warnings though when I run it through lintean: -
Code:
/home/brad/spideroak/wip/packaging/pushpop > lintian pushpop_1.2-1_all.deb
W: pushpop: syntax-error-in-debian-changelog line 5 "found eof where expected first heading"
W: pushpop: binary-without-manpage usr/bin/.exported.funcs

With regard to the errors about binaries without man pages. These are two files: one containing environment vars and the other some exported functions. The directory structure used to create the package is: -
