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::object
File::Find::Object(3pm) User Contributed Perl Documentation File::Find::Object(3pm)NAME
File::Find::Object - An object oriented File::Find replacement
SYNOPSIS
use File::Find::Object;
my $tree = File::Find::Object->new({}, @targets);
while (my $r = $tree->next()) {
print $r ."
";
}
DESCRIPTION
File::Find::Object does same job as File::Find but works like an object and with an iterator. As File::Find is not object oriented, one
cannot perform multiple searches in the same application. The second problem of File::Find is its file processing: after starting its main
loop, one cannot easilly wait for another event and so get the next result.
With File::Find::Object you can get the next file by calling the next() function, but setting a callback is still possible.
FUNCTIONS
new
my $ffo = File::Find::Object->new( { options }, @targets);
Create a new File::Find::Object object. @targets is the list of directories or files which the object should explore.
options
depth
Boolean - returns the directory content before the directory itself.
nocrossfs
Boolean - doesn't continue on filesystems different than the parent.
followlink
Boolean - follow symlinks when they point to a directory.
You can safely set this option to true as File::Find::Object does not follow the link if it detects a loop.
filter
Function reference - should point to a function returning TRUE or FALSE. This function is called with the filename to filter, if the
function return FALSE, the file is skipped.
callback
Function reference - should point to a function, which would be called each time a new file is returned. The function is called with
the current filename as an argument.
next
Returns the next file found by the File::Find::Object. It returns undef once the scan is completed.
item
Returns the current filename found by the File::Find::Object object, i.e: the last value returned by next().
next_obj
Like next() only returns the result as a convenient File::Find::Object::Result object. "$ff->next()" is equivalent to
"$ff->next_obj()->path()".
item_obj
Like item() only returns the result as a convenient File::Find::Object::Result object. "$ff->item()" is equivalent to
"$ff->item_obj()->path()".
$ff->set_traverse_to([@children])
Sets the children to traverse to from the current node. Useful for pruning items to traverse.
$ff->prune()
Prunes the current directory. Equivalent to $ff->set_traverse_to([]).
[@children] = $ff->get_traverse_to()
Retrieves the children that will be traversed to.
[@files] = $ff->get_current_node_files_list()
Gets all the files that appear in the current directory. This value is constant for every node, and is useful to use as the basis of the
argument for "set_traverse_to()".
BUGS
No bugs are known, but it doesn't mean there aren't any.
SEE ALSO
There's an article about this module in the Perl Advent Calendar of 2006: <http://perladvent.pm.org/2006/2/>.
File::Find is the core module for traversing files in perl, which has several limitations.
File::Next, File::Find::Iterator, File::Walker and the unmaintained File::FTS are alternatives to this module.
