if [[ -d "$dir" ]]; then echo "Dir exists $dir"; else echo "dir $dir doesnot exists"; exit 0; fi
and think that multi-line is better readable and maintainable.
Problem #2 "test for matching files" can be solved with a file_exists function.
Code:
file_exists(){
for _i do
[ -f "$_i" ] && return
done
return 1
}
if [[ -d "$dir" ]]
then
echo "Dir exists $dir"
if file_exists "$dir/$filename"*
then
echo "Filename $filename is correct"
else
echo "Filename is not correct"
fi
else
echo "dir $dir doesnot exists"
exit 0
fi
In such a structure I can often omit an exit or return.

Hi,
I am writing a BASH script. I have a list of files and I would like to make sure that each is of a specific pattern (ie *.L2). If not I would like to remove that file. How do I test whether a filename matches a given pattern?
Thanks a lot.

Hi,
I have a directory with around 100k files and files with varying sizes(10GB files to as low as 5KB). All the files are having pipe dilimited records.
I need to append 7 pipes to the end of each record, in each file whose name contains _X3_ and need to append 10 pipes to the end of each... (3 Replies)

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
