It should work just by adding the directory in which the function is to your $FPATH variable. It works in my other environment (Solaris)... And I can just run the function from within a script without having to source it, just not from the command line.
The FPATH variable works in ksh (and only ksh - bash doesn't have it!) provided that:
1.) The files where the functions reside in are mode 4 or 6 to the UID of the calling script. I flag them 644 and give ownership to root:system (on AIX - Linux would be "root:root") usually. They should NOT have the x-bit set! This is important.
2.) Every function should reside in its own file (do NOT bundle functions into files) and the file should be named like the fuction itself. The first executable line in the file should be the function definition:
3.) You have to be aware, that FUNCTIONS ARE NOT SCRIPTS! You can't just execute them on their own. You have to call them from within your scripts:
I work with a collection of these functions since years and maintain my handy little library with all sorts of solutions for day-to-day-scripting.
As I said, I can run the functions from within a script without a problem provided that I set the FPATH with the correct directory.
However, I can't run the function from the command line using 'ksh functionname', even though I have the same setup on another system running solaris instead of red hat which works fine
When you test your functions, do you always create a separate script to call that function?

Hmm I feel kinda stupid for not trying that before. But when I switch to a ksh shell (instead of default bash) and I run just the function name, it works.
I don't understand why is doesn't work when I run it from within the bash shell using 'ksh functionname'
