How to do a smart copy of the files between directories in Perl?

Hi,
I would like to write a Perl code that will do a kind of smart copy between directories.

Can you please help me to write this code in Perl?

The directory structure is like this:

/a/b/c/d/e/productA/bin
/a/b/c/d/e/productA/lib

/a/b/c/d/e/productB/bin
/a/b/c/d/e/productB/lib

/a/b/c/d/e/productC/bin
/a/b/c/d/e/productC/lib

/a/b/c/d/e/bin
/a/b/c/d/e/lib

Open in new window


What I want to do is to copy the files in the bin directories of productA, productB and productC to the bin directory in the e directory.

The same way, I want to copy the files in the lib directories of productA, productB and productC to the lib directory in the e directory.

Before actually copying the files, the code should check if there are any files that conflicts (name conflict) between all the products (This example has 3 products A, B and C but it can be more than three. Also, anything other than bin or lib in e directory means it is a product. Bin adn Lib directories in the e directory are the destination directories). then the code should prompt to the user and ask if he wants to copy. If the user says yes, then it should start copying otherwise it should not do anything. The code should prompt to the user whether there is a conflict or not.


The sudo code is like this:

Ask the input directory from the user (with getoptions)

Loop through all the files in all the child directories of the given directory and push them in to an array.

Loop through all the files in all the child directories of the directories that are in the same level as the input directory and push them to an array. (Let's say if the input is [b]/a/b/c/d/e/productA[/b] then loop through the productb and productC directories. Do not loop through bin and lib in e directory because it is not a product. It is a destination.)

Check if there are any name conflicts between the two arrays.

Tell the user if there are any conflicts and print this information on the screen and ask if he wants to continue. (even if there is no conflict I would like to prompt to the user to say yes or not)

If the user says "no" then do not start copying and exit.

If the user says "yes" then start copying files from the bin directory of the input directory to the bin directory in the "e" directory. And do the same copy for the "lib" directory.

The code should overwrite to the files in the destination directory. 

Open in new window



Example 1 with a conflicting file name:
/a/b/c/d/e/productA/bin/runtool.pl
/a/b/c/d/e/productA/lib/findFiles.pl
/a/b/c/d/e/productA/lib/findPeople.pl

/a/b/c/d/e/productB/bin/runGui.pl
/a/b/c/d/e/productB/lib/findFiles.pl
/a/b/c/d/e/productB/lib/findApples.pl

/a/b/c/d/e/productC/bin/runSky.pl
/a/b/c/d/e/productC/lib/doThis.pl


/a/b/c/d/e/bin/runtool.pl
/a/b/c/d/e/bin/runGui.pl
/a/b/c/d/e/bin/runSky.pl
/a/b/c/d/e/lib/findFiles.pl
/a/b/c/d/e/lib/findPeople.pl
/a/b/c/d/e/lib/findApples.pl
/a/b/c/d/e/lib/doThis.pl

Open in new window



 The code should be able to detect that there is a name conflict in the "lib" directories of productA and productB. and it should tell the user that "/a/b/c/d/e/productB/lib/findFiles.pl" causes conflict. And asks the users if he wants to continue.

If the user says no then it should not copy anything.



Example 2 wit no conflicting file name:
/a/b/c/d/e/productA/bin/runtool.pl
/a/b/c/d/e/productA/lib/findFiles.pl
/a/b/c/d/e/productA/lib/findPeople.pl

/a/b/c/d/e/productB/bin/runGui.pl
/a/b/c/d/e/productB/lib/findDirectories.pl
/a/b/c/d/e/productB/lib/findApples.pl

/a/b/c/d/e/productC/bin/runSky.pl
/a/b/c/d/e/productC/lib/doThis.pl


/a/b/c/d/e/bin/runtool.pl
/a/b/c/d/e/bin/runGui.pl
/a/b/c/d/e/bin/runSky.pl
/a/b/c/d/e/lib/findFiles.pl
/a/b/c/d/e/lib/findPeople.pl
/a/b/c/d/e/lib/findApples.pl
/a/b/c/d/e/lib/doThis.pl

Open in new window



Even though there is no conflict in the file names between the products, the user will be prompted and if he says yes then it will copy the files otherwise it will not do anything.

If there is a conflict and the user says "yes" to continue, which file would you expect to end up in /a/b/c/d/e/bin (or lib)?  A "random" one of the conflict files or a specific one?  If specific, which one (and how can it be determined programmatically since you don't say to ask the user)?

Good point. If there is conflict, it should give the user three options.

Choose the file you want to copy:

1 -> Accept the following file:
               /a/b/c/d/e/productA/lib/findFiles.pl
2 -> Accept the following file:
               /a/b/c/d/e/productB/lib/findFiles.pl
3 -> Quit

Should the script handle sub-directories in bin and lib or is it always a flat directory structure?  In other words, will there ever be /a/b/c/d/e/productA/bin/this/that.pl or /a/b/c/d/e/productB/lib/XML/SAX.pm or similar?

Again a good point.

In the lib directory there will be sub directories. In the bin directory, it is very unlikely but there may be.

So, if there are any sub-directories the sub-directories should be copied as a directory into the lib or the bin directory. And the name conflict should be checked for the sub-directory names only rather than the files they contain, because if the sub-directory names do not conflict, then the files in different sub directories can have same names.

And, if there is a conflict, then the user should be prompted to choose from the given options.

This ended up more complex than I expected but it works...

use File::Copy qw(cp);

use File::Path qw(make_path);
use Term::Prompt;
my $dir = shift or die "Usage: $0 base_dir\n";
chdir $dir or die "could not cd to $dir: $!";
opendir DIR, '.' or die "could not open $dir: $!";
my @dirs = grep { -d $_ and $_ !~ m{^(?:bin|lib|\.+)$}o } readdir DIR;
closedir DIR;
my ($base, %files, %multi);
foreach my $dir (sort @dirs) {
    $base = $dir;
    File::Find::find({wanted => \&search}, $base);
}
if (%multi) {
    foreach my $file (sort keys %multi) {
        my $val = prompt('m', { prompt => 'which file?', title => 'conflict',
                    items => [ 'quit', map { "$_/$file" } @{$files{$file}} ],

        exit unless $val;

    }
} else {
    my $val = prompt('m', { prompt => 'what to do?', title => 'no conflicts',
                items => ['quit', 'no conflicts - continue'], cols => 1,
                display_base => 0 }, '', undef);
    exit unless $val;
}
foreach my $file (keys %files) {
    die "woa!! found conflict for $file after resolutions\n"
        unless (@{$files{$file}} == 1);
#    print "cp $files{$file}[0]/$file\n";
    my $dir = $file;
    $dir =~ s{/[^/]+$}{};
    make_path($dir) unless (-d $dir);
    cp "$files{$file}[0]/$file", $file
            or die "could not copy $files{$file}[0]/$file: $!";
}

sub search {
    return unless -f $_;

@wilcoxon: I am getting the following error:

"make_path" is not exported by the File::Path module

Open in new window


Is there any other way of doing it instead of make_path?

NOTE: I don't have control on the Perl we use in here. And I don't have permission to add any modules.

Thanks,

It sounds like you have the module but it may be an older version.  Try changing:
use File::Path qw(make_path) --> use File::Path qw(mkpath)
make_path(...) --> mkpath(...)
Hopefully you have Term::Prompt installed then.  If not, do you have IO::Prompt installed (IO::Prompt seems better than Term::Prompt but is not as portable (does not work on Windows at least))?

Can you try doing:
perl -e 'use IO::Prompt'

Open in new window

and tell me if that gives an error?  It's possible to do user input without a module but not reinventing the wheel is one of the key advantages to Perl...

Can you ask the sysadmin to install a module?  Both Term::Prompt and IO::Prompt have minimal non-core dependencies (and what they do depend on (except Want in IO::Prompt) are very common modules).

I will try perl -e command tomorrow but I am pretty sure that sysadmin will not install any module for me. Even if they agree to do it, it will take months for them to actually do it.

Is there any other way of doing it? Or can we rewrite the same code in a shell script? It may be easier to do prompt in shell but I am not sure if it is easy to do the rest in a shell script.

What do you think?


By the way, this code does not ask any input from the user in the beginning to decide for the source directory (product) to be copied to the destination.

Is that right?

Since it's a single directory source, it seemed easier to specify that on the command line (eg script.pl directory).  It could be modified to ask.

I see.

So, how can we solve the prompt issue without having the module?

Let's wait and see if you do have IO::Prompt (eg if you get an error from the perl -e command).  If you do, it's pretty simple to change the Term::Prompt syntax.  If you don't then it's more complicated (possibly just include the source for Term::Prompt in the code).

@wilcoxon: The command you wanted me to run returned the following:

% perl -e 'use IO::Prompt'
Can't locate IO/Prompt.pm in @INC (@INC contains: ........................ some paths in here................................... at -e line 1.

Apparently, you don't have Term::Prompt or IO::Prompt.

Can you install modules as part of your code (likely into a different directory than where Perl does) or do the sysadmins insist everything be contained in a single file?  It's common practice to write modules as part of Perl programs so we may be able to go that route.

They would prefer it to be in a single file. Can we do like that?

@wilcoxon: I tried to run the code and I saw an unexpected behavior. The code is supposed to copy the directories and files from one  directory into another without changing the directory structure. In my experience with the code, it does copy the directories with the files inside them individually into the new directory.


The example that I posted in my initial post was like this:

/a/b/c/d/e/productA/bin/runtool.pl
/a/b/c/d/e/productA/lib/findFiles.pl
/a/b/c/d/e/productA/lib/findPeople.pl

/a/b/c/d/e/productB/bin/runGui.pl
/a/b/c/d/e/productB/lib/findDirectories.pl
/a/b/c/d/e/productB/lib/findApples.pl

/a/b/c/d/e/productC/bin/runSky.pl
/a/b/c/d/e/productC/lib/doThis.pl


/a/b/c/d/e/bin/runtool.pl
/a/b/c/d/e/bin/runGui.pl
/a/b/c/d/e/bin/runSky.pl
/a/b/c/d/e/lib/findFiles.pl
/a/b/c/d/e/lib/findPeople.pl
/a/b/c/d/e/lib/findApples.pl
/a/b/c/d/e/lib/doThis.pl

Open in new window


Now I add some sub directories into this example:

/a/b/c/d/e/productA/bin/runtool.pl
/a/b/c/d/e/productA/lib/findFiles.pl
/a/b/c/d/e/productA/lib/findPeople.pl

/a/b/c/d/e/productB/bin/runGui.pl
/a/b/c/d/e/productB/lib/findDirectories.pl
/a/b/c/d/e/productB/lib/findApples.pl
/a/b/c/d/e/productB/lib/standard/file1.pl
/a/b/c/d/e/productB/lib/standard/file1.pl

/a/b/c/d/e/productC/bin/runSky.pl
/a/b/c/d/e/productC/lib/doThis.pl


/a/b/c/d/e/bin/runtool.pl
/a/b/c/d/e/bin/runGui.pl
/a/b/c/d/e/bin/runSky.pl
/a/b/c/d/e/lib/findFiles.pl
/a/b/c/d/e/lib/findPeople.pl
/a/b/c/d/e/lib/findApples.pl
/a/b/c/d/e/lib/doThis.pl
/a/b/c/d/e/lib/standard/file1.pl
/a/b/c/d/e/lib/standard/file1.pl

Open in new window


When I tried to run the code, it copied the files and directories into the source directory instead of the target directory.

Can you please double check if something is wrong in the code?

Thanks,

I'm not following.  Given your revised /a/b/c/d/e/product[ABC] structure, what behavior are you seeing?  When I test (with subdirectories), it copies the files from the product directories into the base //bin and //lib dirs.  Can you please be more specific - what is the exact file structure before running and how does the behavior differ from what you expect?

@Wilcoxon: So, I tried it again and the behavior is like this:

I put the script in a folder called add2PathTest. and I have the following file and the three folders in it:

The content of the add2PathTest folder.  (bin, lib and rel1.3 are folders.)

bin
lib
rel1.3
release2production.pl

Open in new window


I cd to add2PathTest folder and I ran the following command:

release2production.pl rel1.3

Open in new window


After I ran this command, this is what I have:

bin and lib folders are empty. Nothing was copied into these directories.
rel1.3 folder was the source folder where I wanted to copy files and folders from. However, the copy process was done into this folder from within the folders inside it.

Please see the directory structure in the attachment before and after the copy process:

That's what I would expect.  If you are already in add2PathTest dir then you should run
release2production.pl .

Open in new window

If you are not already in add2PathTest then you should run
release2production.pl /path/to/add2PathTest

Open in new window

It will copy from all prod directories under the specified directory to the bin and lib dirs (so you were effectively telling it to copy from rel1.3/*/bin to rel1.3/bin).

@wilcoxon: I need to be in add2PathTest directory. So I will need to use the first code you mentioned. But there will be different products in this directory aside from rel1.3 and I don't want to copy from all of them. Therefore, I need to mention the source directory. How can I do it with the code you sent me?

You can't.  Your original requirements seemed to be to copy from all of them.  This should allow doing so.  The code now requires you to be in the add2PathTest dir when you run it and is run as

To both specify the "source" dir (personally, I'd call it target since you want to copy files to "source"/(bin|lib)) and specify which product dirs, this should do it...

It is run as
release2production.pl source_dir prod1 ... prodX

Open in new window

where the prod dirs specified must be the dir name found under the source_dir (not absolute paths and not sub-sub-dirs).  For example:
release2production.pl /path/to/add2PathTest rel1.3

use strict;
use warnings;
use File::Copy qw(cp);

@wilcoxon: ok. I got your code and I ran the following command when I am in the add2PathTest folder:

release2Production.pl rel1.3

Open in new window



When it said no coflicts, I chose 1 and nothing happened. Nothing is copied.

With that command, you are missing the source/base dir.  If you are in add2PathTest, you still need to specify the dir (.) so it should be:
release2Production.pl . rel1.3

Open in new window

The command you specified says to use rel1.3 as the source/base dir and to copy files from no product dirs (eg nothing is specified on the command line except rel1.3 base dir).

You can tell because the output from your command should look something like:

base dir rel1.3
checking ...
(note the nothing listed as being checked).

Here's a slight mod that will make sure at least 1 product dir is specified...

Now it works as expected in terms of copying files. However, when it comes to detecting same files, it does not work as expected.

This is what happens:

I have some files in rel1.3 directory in the bin and lib directories.

Then I ran the following command:

perl release2Production.pl . rel1.3

Open in new window


This copied the files as expected. This is the output:

Name "Text::Wrap::Columns" used only once: possible typo at release2Production.pl line 373.
base dir .
checking rel1.3...
no conflicts
------------
0) quit                   
1) no conflicts - continue


what to do? (0 - 1) 1

Open in new window



I have the same files are also in rel1.4 directory in the bin and lib directories.

I ran the following command:

perl release2Production.pl . rel1.4

Open in new window


This is the output:

Name "Text::Wrap::Columns" used only once: possible typo at release2Production.pl line 373.
base dir .
checking rel1.4...
no conflicts
------------
0) quit                   
1) no conflicts - continue

Open in new window


The unexpected behavior is, it says "no conflicts" when I try to copy the same files from rel1.4 to the target directory even though all the files are already in the target bin and lib folders because I already copied them from rel1.3 folder. But the code does not detect this conflict.

To clarify: The conflict should be checked between the source and the target folders.

Can you please help me to resolve this part?

Ah.  I thought the conflict detection should only be between the multiple source (product) folders.  I'll update the code - it may take a bit (but I should be able to do it today).

Great. I am waiting for your solution.

Btw, to clarify: The conflict detection should only be between the source the target folders.

For example: If there is already a file in the target location with the same name then the code should notify the user by telling which files causes the conflict.

Shouldn't it also find a conflict if prodA and prodB both contain bin/something.pl (whether or not ./bin/something.pl exists)?

No, it shouldn't find the conflicts between the products. The only conflict that is important is between the product and the target location (./)

The script I posted will both check for conflicts with the dest dir and with other products specified on the command line (it ignores any products not specified when you run the script).

I tried it and it works as expected. But there is a slight usage problem.

When I ran the script the first time there are no conflicts and it works ok. If I ran the script the second time, I have to approve all the conflicting files one by one. And if I have 50 files I have to make a choice for 50 times.

Instead of doing this, is it possible to make it as the following:

If there is a conflict then list all the conflicting files and ask the user to continue or to quit in order to resolve the problem.

This way the user will only make a choice once.

It seems like you have significantly changed your intended use (and requirements) as this question has progressed.

The big problem with what you are now asking is then it will not work for the case in your original question (when there is a conflict between prodA and prodB).  If you describe how you want to resolve this type of conflict, it is definitely possible.

May I suggest closing this question (and awarding points since the code does everything requested in the original question and more) and creating a new question for this modification?  The only "payment" experts get is points for our time.

Sure. I started this new question:

http://www.experts-exchange.com/Programming/Languages/Scripting/Perl/Q_28329207.html

And, the problem you mentioned is not requirement actually. I don't need to check the conflicts between prodA and prodB. If this is already in the code we can just remove it.

The only conflict that I care are:

prod/bin and bin/ 
prod/lib and lib/

@wilcoxon: In the code you sent me, there are sub functions called:

prompt, rangeit, menuit, termwrap anf get_width.

Did you write these functions or are there from different Perl modules?

And can you please tell me why and how we use them in the code?

Thanks,

They are copied from Term::Prompt.  I copied the Term::Prompt code and then removed any subs that weren't used in my code or in code I was calling in Term::Prompt.

In the code, lines 54 and 61 call prompt which calls get_width, menuit, and termwrap.  menuit calls rangeit.

All of them have to do with the options display and getting user input.

Ok. So, these sub functions does not need code review because they are from Term::Prompt to get user input.

And, I assume you did this because I didn't have Term::Prompt module.

Yes.  I did that since you didn't have Term::Prompt installed and said it would be very difficult or impossible to get it installed (see this comment and the following 2 from above).
