tar：
NAME
tar - manual page for tar 1.23
SYNOPSIS
tar [OPTION...] [FILE]...
DESCRIPTION
GNU ‘tar’ saves many files together into a single tape or disk archive, and can restore individual files from the
archive.
Note that this manual page contains just very brief description (or more like a list of possible functionality)
originally generated by the help2man utility. The full documentation for tar is maintained as a Texinfo manual.
If the info and tar programs are properly installed at your site, the command ‘info tar’ should give you access
to the complete manual.
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
-C, --directory=DIR
change to directory DIR
-f, --file=ARCHIVE
use archive file or device ARCHIVE
-j, --bzip2
filter the archive through bzip2
-J, --xz
filter the archive through xz
-p, --preserve-permissions
extract information about file permissions (default for superuser)
-v, --verbose
verbosely list files processed
-z, --gzip
filter the archive through gzip
//常规打包文件夹，打包归档不会删除原文件，-c创建文件、-v显示打包过程、-f表示指定文件
