se.sics.coffee is a library for the Coffee File System. It is able to
|
||||
generate file system images and to extract information from existing
|
||||
images.
|
||||
|
||||
Building:
|
||||
|
||||
./build.sh
|
||||
|
||||
Usage:
|
||||
|
||||
java -jar coffee.jar [-i|e <Coffee file> <file>] [-r <Coffee file>]
|
||||
[-l|s] <file system image>
|
||||
|
||||
Options:
|
||||
|
||||
-i Inserts a new file into the file system.
|
||||
-e Extracts a file from the file system and saves it locally.
|
||||
-r Removes a file from the file system.
|
||||
-l Lists all files.
|
||||
-s Prints file system statistics.
