A function is a function within your current shell. We don't need to start another bash because we can just refer to the function like it is a command.
Guessing the $idir contains a valid comma-separated list of directories, we can rearrange the script to avoid using "for" when we have directory or file names.
This construct works for any number of files and for filenames containing space characters:

file::find::wanted
Wanted(3pm) User Contributed Perl Documentation Wanted(3pm)NAME
File::Find::Wanted - More obvious wrapper around File::Find
VERSION
Version 1.00
SYNOPSIS
File::Find is a great module, except that it doesn't actually find anything. Its "find()" function walks a directory tree and calls a
callback function. Unfortunately, the callback function is deceptively called "wanted", which implies that it should return a boolean
saying whether you want the file. That's not how it works.
Most of the time you call "find()", you just want to build a list of files. There are other modules that do this for you, most notably
Richard Clamp's great File::Find::Rule, but in many cases, it's overkill, and you need to learn a new syntax.
With the "find_wanted" function, you supply a callback sub and a list of starting directories, but the sub actually should return a boolean
saying whether you want the file in your list or not.
To get a list of all files ending in .jpg:
my @files = find_wanted( sub { -f && /.jpg$/ }, $dir );
For a list of all directories that are not CVS or .svn:
my @files = find_wanted( sub { -d && !/^(CVS|.svn)$/ }, $dir ) );
It's easy, direct, and simple.
WHY DO THIS ?
The cynical may say "that's just the same as doing this":
my @files;
find( sub { push @files, $File::Find::name if -f && /.jpg$/ }, $dir );
Sure it is, but File::Find::Wanted makes it more obvious, and saves a line of code. That's worth it to me. I'd like it if find_wanted()
made its way into the File::Find distro, but for now, this will do.
FUNCTIONS
find_wanted( &wanted, @directories )
Descends through @directories, calling the wanted function as it finds each file. The function returns a list of all the files and
directories for which the wanted function returned a true value.
This is just a wrapper around "File::Find::find()". See File::Find for details on how to modify its behavior.
