Class tar

java.lang.Object
  com.ice.tar.tar

All Implemented Interfaces:

TarProgressDisplay

public class tar
extends Object
implements TarProgressDisplay

The tar class implements a weak reproduction of the traditional UNIX tar command. It currently supports creating, listing, and extracting from archives. It also supports GZIP-ed archives with the '-z' flag. See the usage (-? or --usage) for option details.

 usage: com.ice.tar.tar has three basic modes:
 
   com.ice.tar -c [options] archive files...
      Create new archive containing files.
 
   com.ice.tar -t [options] archive
      List contents of tar archive
 
   com.ice.tar -x [options] archive
      Extract contents of tar archive.
 
 options:
    -f file, use 'file' as the tar archive
    -v, verbose mode
    -z, use GZIP compression
    -D, debug archive and buffer operation
    -b blks, set blocking size to (blks * 512) bytes
    -o, write a V7 format archive rather than ANSI
    -u name, set user name to 'name'
    -U id, set user id to 'id'
    -g name, set group name to 'name'
    -G id, set group id to 'id'
    -?, print usage information
    --trans, translate 'text/*' files
    --mime file, use this mime types file and translate
    --usage, print usage information
    --version, print version information
 
 The translation options will translate from local line
 endings to UNIX line endings of '\\n' when writing tar
 archives, and from UNIX line endings into local line endings
 when extracting archives.
