Drag the feed's URL to the dialog box that appears. Other environments may use other systems. For example, if you are a ROX desktop user, drag the link to AddApp instead.

Alternatively, to run it from the command-line:

$ 0launch

The 0alias command can be used to create a short-cut to run it again later.

If you don't have the 0launch command, download it from the web-site, which also contains documentation about how the Zero Install system works.

Full name


GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. If you use ppss or pexec you will find GNU parallel will often make the command easier to read. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs. For each line of input GNU parallel will execute command with the line as arguments. If no command is given, the line of input is executed. Several lines will be run in parallel. GNU parallel can often be used as a substitute for xargs or cat | sh.
