文件打包命令，把一组文件或目录打到一个文件里。还可以选择是否压缩、哪种压缩。或者反之把它打包的文档还原并拆成一个一个的文档。
tar
-c: 建立压缩档案
-x：解压
-t：查看内容
-r：向压缩归档文件末尾追加文件
-u：更新原压缩包中的文件
这五个是独立的命令，压缩解压都要用到其中一个，可以和别的命令连用但只能用其中一个。下面的参数是根据需要在压缩或解压档案时可选的。
-z：有gzip属性的
-j：有bz2属性的
-Z：有compress属性的
-v：显示所有过程
-O：将文件解开到标准输出
下面的参数-f是必须的
-f: 使用档案名字，切记，这个参数是最后一个参数，后面只能接档案名。
# tar -cf all.tar *.jpg
这条命令是将所有.jpg的文件打成一个名为all.tar的包。-c是表示产生新的包，-f指定包的文件名。
# tar -rf all.tar *.gif
这条命令是将所有.gif的文件增加到all.tar的包里面去。-r是表示增加文件的意思。
# tar -uf all.tar logo.gif
这条命令是更新原来tar包all.tar中logo.gif文件，-u是表示更新文件的意思。
# tar -tf all.tar
这条命令是列出all.tar包中所有文件，-t是列出文件的意思
# tar -xf all.tar
这条命令是解出all.tar包中所有文件，-x是解开的意思
压缩
tar –cvf jpg.tar *.jpg //将目录里所有jpg文件打包成tar.jpg
tar –czf jpg.tar.gz *.jpg //将目录里所有jpg文件打包成jpg.tar后，并且将其用gzip压缩，生成一个gzip压缩过的包，命名为jpg.tar.gz
tar –cjf jpg.tar.bz2 *.jpg //将目录里所有jpg文件打包成jpg.tar后，并且将其用bzip2压缩，生成一个bzip2压缩过的包，命名为jpg.tar.bz2
tar –cZf jpg.tar.Z *.jpg //将目录里所有jpg文件打包成jpg.tar后，并且将其用compress压缩，生成一个umcompress压缩过的包，命名为jpg.tar.Z
rar a jpg.rar *.jpg //rar格式的压缩，需要先下载rar for linux
zip jpg.zip *.jpg //zip格式的压缩，需要先下载zip for linux
解压
tar –xvf file.tar //解压 tar包
tar -xzvf file.tar.gz //解压tar.gz
tar -xjvf file.tar.bz2 //解压 tar.bz2
tar –xZvf file.tar.Z //解压tar.Z
unrar e file.rar //解压rar
unzip file.zip //解压zip
总结
1、*.tar 用 tar –xvf 解压
2、*.gz 用 gzip -d或者gunzip 解压
3、*.tar.gz和*.tgz 用 tar –xzf 解压
4、*.bz2 用 bzip2 -d或者用bunzip2 解压
5、*.tar.bz2用tar –xjf 解压
6、*.Z 用 uncompress 解压
7、*.tar.Z 用tar –xZf 解压
8、*.rar 用 unrar e解压
9、*.zip 用 unzip 解压

1 Usage: tar [OPTION...] [FILE]... 2 GNU `tar‘ saves many files together into a single tape or disk archive, and can 3 restore individual files from the archive. 4 5 Examples: 6 tar -cf archive.tar foo bar # Create archive.tar from files foo and bar. 7 tar -tvf archive.tar # List all files in archive.tar verbosely. 8 tar -xf archive.tar # Extract all files from archive.tar. 9 10 Main operation mode: 11 12 -A, --catenate, --concatenate append tar files to an archive 13 -c, --create create a new archive 14 -d, --diff, --compare find differences between archive and file system 15 --delete delete from the archive (not on mag tapes!) 16 -r, --append append files to the end of an archive 17 -t, --list list the contents of an archive 18 --test-label test the archive volume label and exit 19 -u, --update only append files newer than copy in archive 20 -x, --extract, --get extract files from an archive 21 22 Operation modifiers: 23 24 --check-device check device numbers when creating incremental 25 archives (default) 26 -g, --listed-incremental=FILE handle new GNU-format incremental backup 27 -G, --incremental handle old GNU-format incremental backup 28 --ignore-failed-read do not exit with nonzero on unreadable files 29 --level=NUMBER dump level for created listed-incremental archive 30 -n, --seek archive is seekable 31 --no-check-device do not check device numbers when creating 32 incremental archives 33 --no-seek archive is not seekable 34 --occurrence[=NUMBER] process only the NUMBERth occurrence of each file 35 in the archive;

1 TAR(1) User Commands TAR(1) 2 3 4 5 NAME 6 tar - manual page for tar 1.26 7 8 SYNOPSIS 9 tar [OPTION...] [FILE]... 10 11 DESCRIPTION 12 GNU `tar‘ saves many files together into a single tape or disk archive, and can restore individual files from the archive. 13 14 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 documenta‐ 15 tion 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 16 manual. 17 18 EXAMPLES 19 tar -cf archive.tar foo bar 20 # Create archive.tar from files foo and bar. 21 22 tar -tvf archive.tar 23 # List all files in archive.tar verbosely. 24 25 tar -xf archive.tar 26 # Extract all files from archive.tar. 27 28 DEFAULTS 29 *This* tar installation defaults to: 30 31 --format=gnu -f- -b20 --quoting-style=escape --rmt-command=/sbin/rmt --rsh-command=/usr/bin/rsh 32 33 Main operation mode: 34 -A, --catenate, --concatenate 35 append tar files to an archive 36 37 -c, --create 38 create a new archive 39 40 -d, --diff, --compare 41 find differences between archive and file system 42 43 --delete 44 delete from the archive (not on mag tapes!) 45 46 -r, --append 47 append files to the end of an archive 48 49 -t, --list 50 list the contents of an archive 51 52 --test-label 53 test the archive volume label and exit 54 55 -u, --update 56 only append files newer than copy in archive 57 58 -x, --extract, --get 59 extract files from an archive 60 61 Common options: 62 -C, --directory=DIR 63 change to directory DIR 64 65 -f, --file=ARCHIVE 66 use archive file or device ARCHIVE 67 68 -j, --bzip2 69 filter the archive through bzip2 70 71 -J, --xz 72 filter the archive through xz 73 74 -p, --preserve-permissions 75 extract information about file permissions (default for superuser) 76 77 -v, --verbose 78 verbosely list files processed 79 80 -z, --gzip 81 filter the archive through gzip 82 83 84 Operation modifiers: 85 --check-device 86 check device numbers when creating incremental archives (default) 87 88 -g, --listed-incremental=FILE 89 handle new GNU-format incremental backup 90 91 -G, --incremental 92 handle old GNU-format incremental backup 93 94 --ignore-failed-read 95 do not exit with nonzero on unreadable files 96 97 --level=NUMBER 98 dump level for created listed-incremental archive 99 100 -n, --seek 101 archive is seekable 102 103 --no-check-device 104 do not check device numbers when creating incremental archives 105 106 --no-seek 107 archive is not seekable 108 109 --occurrence[=NUMBER] 110 process only the NUMBERth occurrence of each file in the archive;
