expand extracts a file stored in a cabinet file (.cab).
Usage
wine expand source_file destination_file
source_file - file name of the cabinet file
destination_file - path and filename of file to be extracted.
Note: Wine's expand does not support all the command line options available from the Microsoft version of the tool.
There is a third party tool called cabextract available on many Linux
distributions which supports many advanced features not yet supported by
expand. Cabextract is free software under the GPL.
Examples
If you have a file called cow.cab which contains a file named moo.txt you could extract it with:
wine expand cow.cab moo.txt
