linux命令tar

linux命令tar   [root@test flume]# tar --help Usage: tar [OPTION...] [FILE]... GNU `tar' saves many files together into a single tape or disk archive, and can restore individual files from the archive.   Examples:   tar -cf archive.tar foo bar  # Create archive.tar from files foo and bar.   tar -tvf archive.tar         # List all files in archive.tar verbosely.   tar -xf archive.tar          # Extract all files from archive.tar.    Main operation mode:     -A, --catenate, --concatenate   append tar files to an archive   -c, --create               create a new archive   -d, --diff, --compare      find differences between archive and file system       --delete               delete from the archive (not on mag tapes!)   -r, --append               append files to the end of an archive   -t, --list                 list the contents of an archive       --test-label           test the archive volume label and exit   -u, --update               only append files newer than copy in archive   -x, --extract, --get       extract files from an archive    Operation modifiers:         --check-device         check device numbers when creating incremental                              archives (default)   -g, --listed-incremental=FILE   handle new GNU-format incremental backup   -G, --incremental          handle old GNU-format incremental backup       --ignore-failed-read   do not exit with nonzero on unreadable files       --level=NUMBER         dump level for created listed-incremental archive   -n, --seek                 archive is seekable       --no-check-device      do not check device numbers when creating                              incremental archives       --no-seek              archive is not seekable       --occurrence[=NUMBER]  process only the NUMBERth occurrence of each file                              in the archive; this option is valid only in                              conjunction with one of the subcommands --delete,                              --diff, --extract or --list and when a list of                              files is given either on the command line or via                              the -T option;
