Test existance of a file

Hi,

I need to find out if a particular file exists and i am using if with -e option.

Scenarion is like

There is a possibility of two files having nomaincluture like below
First file = abc20101028.somthing
Second File = abc20101028.somthing.done

I need to check abc20101028.somthing exists (Somthing is anything except "done")
Code:
tdate=20101028
if [ -e abc*$tdate*]  # it should not check for done file
then
     if [-e abc*$tdate*done]
     then
         continue
     else
         echo "Done file missing"
     fi
else
    echo "Original File missing"
fi

But in the above logic in the first IF condition, it will return true eve if original is missed but "done" file exists. How can I overcome this.

I tried with
Code:
 ls abc*$tdate*[^done]

but no luck.....
Thank you....

Plack::Session::Store::File(3pm)			User Contributed Perl Documentation			  Plack::Session::Store::File(3pm)

NAME
Plack::Session::Store::File - Basic file-based session store SYNOPSIS
use Plack::Builder; use Plack::Middleware::Session; use Plack::Session::Store::File; my $app = sub { return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ]; }; builder { enable 'Session', store => Plack::Session::Store::File->new( dir => '/path/to/sessions' ); $app; }; # with custom serializer/deserializer builder { enable 'Session', store => Plack::Session::Store::File->new( dir => '/path/to/sessions', # YAML takes it's args the opposite order serializer => sub { YAML::DumpFile( reverse @_ ) }, deserializer => sub { YAML::LoadFile( @_ ) }, ); $app; }; DESCRIPTION
This implements a basic file based storage for session data. By default it will use Storable to serialize and deserialize the data, but this can be configured easily. This is a subclass of Plack::Session::Store and implements its full interface. METHODS
new ( %params ) The %params can include dir, serializer and deserializer options. It will check to be sure that the dir is writable for you. dir This is the directory to store the session data files in, if nothing is provided then "/tmp" is used. serializer This is a CODE reference that implements the serialization logic. The CODE ref gets two arguments, the $value, which is a HASH reference to be serialized, and the $file_path to save it to. It is not expected to return anything. deserializer This is a CODE reference that implements the deserialization logic. The CODE ref gets one argument, the $file_path to load the data from. It is expected to return a HASH reference. BUGS
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT. AUTHOR
