Copying files

[boshu]

Dear all,

I need to copy a set of files every once in a while from my build env to a shared drive.
The set of files are same, names may vary but they come with same extension.

So far I am doing it manually. I wish it could be done using a script which would be
less error prone.

List of files I need to copy every time:

*.axf
*.fls
*.txt
*.err
*.dummy
*.log
*.cfg

Build evn folder where the files are generated:

HW
HW\MODEM\
HW\MODEM\OCEAN\12345.axf
HW\MODEM\OCEAN\12345.err
HW\MODEM\OCEAN\core_dump.log
HW\MODEM\OCEAN\DUMMY\ocean.fls

I need to make sure that when I copy the files, the folder structure is maintained. That is,
I need to create the base folders first, e.g, to copy core_dump.log in example above I need to
create HW\MODEM\OCEAN\ and then copy the file underneat.

Can you please help How can I do it in a script, perl or DOS?

Thanks in advance.

File::Path
File::Find
File::Copy
File::Basename

The modules will be help to complete the needs.

For example:

#!/usr/bin/perl
use strict;
use warnings;

use File::Find;
use File::Path qw(make_path);
use File::Basename;
use File::Copy;

my @directories_to_search = ('/home/david/Programming/data');
my @suffixes = qw(.axf .fls .txt .err .dummy .log .cfg);

find(\&wanted, @directories_to_search);

sub wanted{
    my($filename, $directories, $suffix) = fileparse($File::Find::name, @suffixes);
    if ($suffix){
        my $target_dir = "/home/david/test/$directories";
        make_path($target_dir);
        copy($File::Find::name,"$target_dir/$filename$suffix") or die "Copy failed: $!";
    }

    print "Copied$filename$suffix\n";
}

Hi David

The solution works fine with all file types (I have tried .axf .fls .txt .err .dummy .log .cfg ) except for the object file (".o").

Here is the script I used:

#!/usr/bin/perl
use strict;
use warnings;

use File::Find;
use File::Path qw(make_path);
use File::Basename;
use File::Copy;

# Target Directory
my @directories_to_search = ('HW/TARGET_PLATFORM/MODEM_DEBUG');
#my @suffixes = qw( .axf .fls .txt .cfg .log );
my @suffixes = qw(.o);


find(\&wanted, @directories_to_search);
sub wanted{
    my($filename, $directories, $suffix) = fileparse($File::Find::name, @suffixes);

    if ($suffix){
	my $target_dir = "/home/mmhuqx/test/$directories";
	make_path($target_dir);
	copy($File::Find::name,"$target_dir/$filename$suffix") or die "Copy failed: $!";
    }
    print "Copied $filename$suffix\n";
    
}

Here are the object files in my env:

:/vobs/system-build> ls HW/TARGET_PLATFORM/MODEM_DEBUG/obj/cm/
cm.o       cmc_op1.o  cmm.o      cms.o  cmc.o      cmc_op2.o  cmm_op1.o  dir.dummy

When I run the script it gives me following error:

[tcsh] boshu@rom23:/vobs/system-build/HW/TARGET_PLATFORM/MODEM_DEBUG> perl ~/recursive_copy.pl

I could not figure out what causes the error. Is the file type/suffix syntax I am using wrong?

I don't see what causes that error. Taking a second look at the script I see that the print statement should be inside the if block because we only want to print info about the files with the desired extension, since they are the only files to be copied. Try putting the print statement before the copy statement so we can see what it is going to try to copy before the error occurs. The following may work, or at least print better information for debugging:

#!/usr/bin/perl
use strict;
use warnings;

use File::Find;
use File::Path qw(make_path);
use File::Basename;
use File::Copy;

# Target Directory
#my @directories_to_search = ('HW/TARGET_PLATFORM/MODEM_DEBUG');
my @directories_to_search = ('/home/david/Programming/data');
#my @suffixes = qw( .axf .fls .txt .cfg .log );
my @suffixes = qw(.o);


find(\&wanted, @directories_to_search);
sub wanted{
    my($filename, $directories, $suffix) = fileparse($File::Find::name, @suffixes);

    if ($suffix){
	#my $target_dir = "/home/mmhuqx/test/$directories";
        my $target_dir = "/home/david/Programming/test/$directories";
	make_path($target_dir);
        print "Try to copy $File::Find::name ... Extension is $suffix\n";
	copy($File::Find::name,"$target_dir/$filename$suffix") or die "Copy failed: $!";
        #print only if copied.
        #print "Copied $File::Find::name ... Extension is $suffix\n";
    }   
}

I found my mistake.
my @suffixes = qw( .axf .fls .txt .cfg .log .o);
is not quite right because each pattern is treated as a regex (regular expression) and the dot is a special regex character which needs to be 'escaped' by preceding it with a backslash in order to represent a dot character in the extension. Instead we should escape the dot in all the patterns, like this: my @suffixes = qw( \.axf \.fls \.txt \.cfg \.log \.o);

Does the following script do what you want?

#!/usr/bin/perl
use strict;
use warnings;

use File::Find;
use File::Path qw(make_path);
use File::Basename;
use File::Copy;

# Target Directory
#my @directories_to_search = ('HW/TARGET_PLATFORM/MODEM_DEBUG');
my @directories_to_search = ('/home/david/Programming/data');

#my @suffixes = qw( \.axf \.fls \.txt \.cfg \.log );
my @suffixes = qw(\.o);#Backslash to escape regex special character dot ('.')

find(\&wanted, @directories_to_search);
sub wanted{
    my($filename, $directories, $suffix) = fileparse($File::Find::name, @suffixes);

    if ($suffix){
	#my $target_dir = "/home/mmhuqx/test/$directories";
        my $target_dir = "/home/david/Programming/test/$directories";
	make_path($target_dir);
        print "Try to copy $File::Find::name ... Extension is $suffix\n";
	copy($File::Find::name,"$target_dir/$filename$suffix") or die "Copy failed: $!";
        #print only if copied.
        #print "Copied $File::Find::name ... Extension is $suffix\n";
    }   
}

Hi David. This is perfect now. Working as intended!
Many thanks.

Before closing this thread as Solved I would like to ask one more thing:
Will it work also in windows env?

[d5e5]

I haven't tested it under Windows, only Linux. However I don't see any reason why it shouldn't work just as well in a Windows environment.
