One problem associated with crowd sourcing your work is that you won't know how to fix it.

Hi, this is confusing way to write code

sub yada { ... }
print ...;
yada();
sub yadda {}
print...;
yadda();

If there is a problem with yada, or with the way you call yada, its difficult to tell, for no real reason, code doesn't need to be that confusing

You should write code like this

#!/usr/bin/perl --
Main( @ARGV );
exit( 0 );
sub Main {
    print ...;
    yada();
    print ...;
    yadda();
    ...;
}
sub yada { ... }
sub yadda { ... }

Why write code this way?

Well if there is a problem with yadda or the way you call yada

Its super easy to delete all parts of the program that are not yada and then you you can fix yada easily,

Even if yadda is only a smart part of your large program

If you want to figure this out yourself this is what you have to do

If you want other people to help you figure this out, this is what you have to do

Are you going to do this?

Who gave you that suggestion and where do you have problems applying that suggestion?

i passed my sub routine before html conversion and call it inside if condition inside the html conversion part

Error: Unexpected directory configuration. Expected single rev* +folder, found 0 folder(s) at ./generate_dcms_html.pl line 404,

Perl tells you the problematic line number in the error message.

You posted a lot of code, but it is not clear to me, which line of the code corresponds to the line number 404 from the error message. Maybe the code around that line number is more relevant?

Actually i had tried that suggestion part to link some files.Instead i had also tried another sub routine part that is DelTaskFiles subroutine to remove all task.* files from the destination folder.
But this subroutine fails to unlink all task.* files from its folders AND SUB FOLDERS
This sub routine should be done before renaming the directories(i.e before rename_dirs subroutine).I had tried to remove all files which starts with task from its folders and sub folders at destination directory .
Here my code is not unlinking the task.* from the folders and subfolders
Help me to fix it.If this subroutine is fixed no need to use my suggestion part

Note that in programming, there is a huge difference between the word link, and the word unlink.

The word link is commonly used for the linker program.

The word unlink is commonly used for the system call named unlink, which also exists in Perl as unlink.

You seem to want to use unlink, but you say link. This is highly confusing.

You still have not answered my original question, as to who gave you that suggestion and why they gave the suggestion to you.

If you are trying to get solutions for suggestions and help you got from another place, please stop doing this. This website is for learning and using Perl and not for doing your school and work assignments.

As you have repeatedly ignored attempts to help you find learning resources, I can only think that you are acting in bad faith.
