I have a cut command and i want to make it parameterized.
e.g
Code:
cut -f1-$some_value -d"/" $file_path
so in above e.g $some_value could be a number. $file_path is a path to a file.
But I am not able to execute the above.
The $file_path actually opens the file .....I want it to be just some path e.g /a/b/c/ and cut fields from 1-$some_value
How can this be achieved ?

plack::session::store::file
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.
