Hello everyone. I'm new both to the forum and to unix scripting, and this website has been very useful in putting together a script I am working on. However, I have run into a bit of a snag, which is why I have come here seeking help. First I will say what I am trying to do, and then what I have done so far.
I am trying to download weather model data for a meteorological program called GEMPAK, and the models update ever so often and filenames are based on timestamp and model type. An example filename is 2011051800_nam242.gem
These files take up a LOT of space (this directory alone is 21 gig!), so as you can imagine, after downloading the files I want to delete the old ones. Even more so, I do not need the *entire* directory, just the last 2 day's worth at most.
So, here is what I have done so far.
Now I have the entire directory downloaded in the proper hierarchy, an the script will remove items older than 4 days. However, when the script runs again, it downloads the files I just deleted all over again, and I am trying not to keep too much space with files I don't need. So, my question is, can anyone help me find a way to either download 'x' amount of files, or only after 'x' timestamp? Or maybe another way I do not know about? Thank you very much in advance.
Kindly help us... Is there a way in linux how we'll be able to check which workstation is downloading files from the internet and what file is it? Please put into consideration that our linux has a firewall.

LIQUIDSOAP(1) General Commands Manual LIQUIDSOAP(1)NAME
liquidsoap - a multimedia streaming language
SYNOPSIS
liquidsoap [options] [script|expression]
DESCRIPTION
Liquidsoap is a programming language for describing multimedia streaming systems. It is very flexible, making simple things simple but
giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators
including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support
custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or
even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is
possible via telnet or socket.
Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possi-
ble to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script
will be read from standard input if - is given as script filename. Information about scripting liquidsoap is available on our website:
http://savonet.sf.net/
If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line
scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.
OPTIONS -
Read script from standard input.
-- Stop parsing the command-line and pass subsequent items to the script.
--debug
Print debugging log messages.
--dynamic-plugins-dir path
