Parallel processing
I have 10,000 + files, each of which I need to zip using bzip2.
Is ti possible to use bash to create 8 parallel streams sending a new file to be processed from the list when one of the others has finished?

ARK(1) KDE User's Manual ARK(1)
NAME
ark - KDE archiving tool
SYNOPSIS
ark [-b] [-a] [-e] [-c] [-f suffix] [-p] [-t file] [-d] [-o directory] [KDE Generic Options] [Qttm Generic Options]
DESCRIPTION
Ark is a program for managing various compressed file formats within KDE. Archives can be viewed, extracted, created and modified with Ark.
The program can handle various formats such as tar, gzip, bzip2, zip, rar (when the appropriate libraries or command-line programs are in-
stalled).
OPERATION MODES
Ark can be used either as a stand-alone GUI program as well as a command-line program in order to perform some specific tasks.
If invoked without the -b (--batch) or -c (--add) options, Ark is started as a normal GUI program.
When the -b (--batch) option is used, Ark can be used to extract the contents of one or more files directly from the command-line, without
launching its GUI.
When the -c (--add) option is used, Ark prompts for files that should be added to a new archive or to an existing archive.
OPTIONS
-d, --dialog
Show a dialog for specifying the options for a batch or add operation.
-o, --destination directory
Default the extraction directory to directory. If not passed, the current path is used.
Options for adding files
-c, --add
Query the user for an archive filename and add specified files to it. Quit when finished.
-t, --add-to filename
Add the specified files to filename. Create archive if it does not exist. Quit when finished.
-p, --changetofirstpath
Change the current directory to the first entry and add all other entries relative to this one.
-f, --autofilename suffix
Automatically choose a filename, with the selected suffix (for example rar, tar.gz, zip or any other supported types).
Options for batch extraction
b, --batch
Use the batch interface instead of the usual dialog. This option is implied if more than one url is specified.
-e, --autodestination
The destination argument will be set to the path of the first file supplied.
-a, --autosubfolder
Archive contents will be read, and if detected to not be a single folder archive, a subfolder by the name of the archive will be
created.
EXAMPLES
ark --batch archive.tar.bz2
Will extract archive.tar.bz2 into the current directory without showing any GUI.
ark -b -d archive.tar.bz2 archive2.zip
Will first show an extraction options dialog and then extract both archive.tar.bz2 and archive2.zip into the directory chosen in the
dialog.
ark --add-to my-archive.zip photo1.jpg text.txt
Will create my-archive.zip if does not exist and then add photo1.jpg and text.txt to it.
