Searching for files starting with same names
Hi All ,
I am new to UNIX.
I have a requirement where user transfers 10-15 files into a directory "/upload".
File name will be like T1234_H and T1234_D or R1234_H and R1234_D .
The _H and _D files are associated to each other.They must always be together in the server.
Once the files are transferred I need to perform a check if the file T1234_H has it associated file T1234_D and then move these files to /process/Tfiles directory.
If the file T1234_H is only present in the directory "/upload" and there is no T1234_D file or vice versa the program shouldn't move the file to /upload/Tfiles path and it should throw me an error saying _D file is missing and do the same thing to R1234_H and R1234_D and move to directory /process/Rfiles.
You may think why can't you move the files T1234_H and T1234_D directly to /upload/Tfiles directory rather than doing all this.
But the requirement is to check the files with same name(first 5 chars) say T1234_H and T1234_D both are present in the /upload path and then move these to new path(/process/Tfiles ) based on the first letter of the file name "T" or "R" for processing data in the file.
Regards,
Ravi

dbix::class::inflatecolumn::file
DBIx::Class::InflateColumn::File(3) User Contributed Perl Documentation DBIx::Class::InflateColumn::File(3)
NAME
DBIx::Class::InflateColumn::File - DEPRECATED (superseded by DBIx::Class::InflateColumn::FS)
Deprecation Notice
This component has a number of architectural deficiencies that can quickly
drive your filesystem and database out of sync and is not recommended for
further use. It will be retained for backwards compatibility, but no new
functionality patches will be accepted. Please consider using the much more
mature and actively supported DBIx::Class::InflateColumn::FS. You can set
the environment variable DBIC_IC_FILE_NOWARN to a true value to disable
this warning.
SYNOPSIS
In your DBIx::Class table class:
use base 'DBIx::Class::Core';
__PACKAGE__->load_components(qw/InflateColumn::File/);
# define your columns
__PACKAGE__->add_columns(
"id",
{
data_type => "integer",
is_auto_increment => 1,
is_nullable => 0,
size => 4,
},
"filename",
{
data_type => "varchar",
is_file_column => 1,
file_column_path =>'/tmp/uploaded_files',
# or for a Catalyst application
# file_column_path => MyApp->path_to('root','static','files'),
default_value => undef,
is_nullable => 1,
size => 255,
},
);
In your Catalyst::Controller class:
FileColumn requires a hash that contains IO::File as handle and the file's name as name.
my $entry = $c->model('MyAppDB::Articles')->create({
subject => 'blah',
filename => {
handle => $c->req->upload('myupload')->fh,
filename => $c->req->upload('myupload')->basename
},
body => '....'
});
$c->stash->{entry}=$entry;
And Place the following in your TT template
Article Subject: [% entry.subject %]
Uploaded File:
<a href="/static/files/[% entry.id %]/[% entry.filename.filename %]">File</a>
Body: [% entry.body %]
The file will be stored on the filesystem for later retrieval. Calling delete on your resultset will delete the file from the filesystem.
Retrevial of the record automatically inflates the column back to the set hash with the IO::File handle and filename.
DESCRIPTION
InflateColumn::File
METHODS
