== Advanced usage (by example ==
*Unrar files in parallel*
Unrarring some files in parallel can be as easy as:
`./ppss.sh standalone -d ./dir-with-rars -c 'unrar x "$ITEM" ./output-dir'
However, this may result in the outcome that all extracted files are dumped in the directory output-dir. This may not be wat you want. If you want to extract the files contained within each RAR-file into it's own directory. We need to perform two steps:
# Create a directory for each item in /output-dir
# Unrar the files into the individual directories.
Step 1: making directories based on the name of the RAR file:
`/ppss.sh standalone -d ./dir-with-rars -c 'ITEM=`basename "$ITEM"`; mkdir ./output-dir/"$ITEM"'`
Explanation: by default, each item consists of the full or relative path to that item. An item will expand as "./dir-with-rars/filename.rar". However, the directory name must be based only on the filename. So the unix build-in 'basename' is used to extract the filename from the item and use it to create the directory name.
As you can see, it is no problem to use multiple commands within the -c option, by using ';'.
Step 2: extracting the files of each RAR file into it's own directory.
`./ppss.sh standalone -d ./dir-with-rars -c 'ITEM_DIR=`basename "$ITEM"`; unrar x "$ITEM" ./output-dir/"$ITEM_DIR"'`
In this example, we use the basename command again to be able to specify the output directory based on the supplied ITEM name.
Ofcourse, it is possible to put this all in one command:
`./ppss.sh standalone -d ./dir-with-rars -c 'ITEM_DIR=`basename "$ITEM"`; mkdir ./output-dir/"$ITEM_DIR"; unrar x "$ITEM" ./output-dir/"$ITEM_DIR"'`
