How to download and record any video stream to disk using VLC

in

You can download, view and record any type of video stream (including Real) VLC 0.8.x can handle. This works perfectly well using Mac OS X as well.

In most cases, you must go for the link inside the site's source code. An example is a news video stream which uses the WMP plug-in: view the page source, copy the MMS link, and paste it in the proper field in the VLC dialog window (see below). Then, assuming VLC is already running:

Copy files and directories recursively with tar

in

Copying a directory tree and its contents to another filesystem using


cp -pR directory /newplace

doesn't always do the job.

Using tar instead will preserve ownership, permissions, and timestamps. This neat trick allows using tar to perform a recursive copy without creating an intermediate tar file and overcoming all cp shortcomings.

To copy all of the files and subdirectories in the current working directory to the directory /target, use:


tar cf - * | ( cd /target; tar xfp -)
