Linux文件归档工具——tar
Linux打包压缩命令——tar
一tar工具的介绍
Tar（Tape ARchive，磁带归档的缩写）
NAME
tar - manual page for tar 1.26 SYNOPSIS
tar [OPTION...] [FILE]... DESCRIPTION
GNU `tar' saves many files together into a single tape or disk archive, and can restore indi‐
vidual files from the archive. Note that this manual page contains just very brief description (or more like a list of possi‐
ble 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
二tar工具的使用
tar [OPTION]...
(1) 创建归档
tar -c -f /PATH/TO/SOMEFILE.tar FILE...
(2) 追加文件至归档
注：不支持对压缩文件追加
tar -r -f /PATH/TO/SOMEFILE.tar FILE...
(3) 查看归档文件中的文件列表
tar -t -f /PATH/TO/SOMEFILE.tar
(4) 展开归档
tar -x -f /PATH/TO/SOMEFILE.tar
tar -x -f /PATH/TO/SOMEFILE.tar -C /PATH/
(5) 结合压缩工具实现：归档并压缩
-j: bzip2, -z: gzip, -J: xz
（一）对文件进行打包，并且显示过程
-c表示创建打包文件，和压缩工具一样，要指明对应的后缀
-f表示打包到哪个文件里面
对整个目录进行打包

打包的文件变小了，但是实际上没有压缩
[root@centos72 ~]# ls /app/sysconfig.tar -l
-rw-r--r-- 1 root root 235520 May 3 10:10 /app/sysconfig.tar
[root@centos72 ~]# ls /app/sysconfig.tar -lh
-rw-r--r-- 1 root root 230K May 3 10:10 /app/sysconfig.tar
[root@centos72 ~]# du -sh /etc/sysconfig/
368K /etc/sysconfig/
（二）对文件进行打包并且压缩
结合压缩工具实现：归档并压缩 -j: bzip2, -z: gzip, -J: xz
[root@centos72 ~]# tar -zcf /app/sysconfig.tar.gz /etc/sysconfig/
tar: Removing leading `/' from member names
[root@centos72 ~]# tar -Jcf /app/sysconfig.tar.xz /etc/sysconfig/
tar: Removing leading `/' from member names
[root@centos72 ~]# tar -jcf /app/sysconfig.tar.bz2 /etc/sysconfig/
tar: Removing leading `/' from member names
[root@centos72 ~]# ls /app/ -lt
total 4272
-rw-r--r-- 1 root root 38103 May 3 10:27 sysconfig.tar.bz2

-rw-r--r-- 1 root root 235520 May 3 10:10 sysconfig.tar

上面提示tar: Removing leading `/' from member names无关紧要的，如果你显示，那么就在f前面加上P即可
参考文档：https://blog.51cto.com/13447608/2105102
[root@centos72 ~]# tar -jcPf /app/sysconfig.tar.bz2 /etc/sysconfig/
[root@centos72 ~]# tar -JcPf /app/sysconfig.tar.xz /etc/sysconfig/
[root@centos72 ~]# tar -zcPf /app/sysconfig.tar.gz /etc/sysconfig/
（三）查看归档文件中的文件列表
tar -t -f /PATH/TO/SOMEFILE.tar
压缩与否都有效
[root@centos72 ~]# tar -tvf /app/sysconfig.tar.gz

（四）对文件进行解压缩
展开归档
tar -x -f /PATH/TO/SOMEFILE.tar 解压到当前目录
tar -x -f /PATH/TO/SOMEFILE.tar -C /PATH/ 解压到特定的目录
[root@centos72 ~]# tar xvf /app/sysconfig.tar.gz -C /app/
[root@centos72 ~]# ls /app -lth

解压缩文件大小和原目录里面的文件大小是一样的，说明解压缩成功了
[root@centos72 ~]# du -sh /etc/sysconfig/
368K /etc/sysconfig/
[root@centos72 ~]# du -sh /app/etc/sysconfig/
368K /app/etc/sysconfig/

drwxr-xr-x. 6 root root 4096 May 2 14:46 /etc/sysconfig/
[root@centos72 ~]# ll /app/etc/sysconfig/ -d
drwxr-xr-x 6 root root 4096 May 2 14:46 /app/etc/sysconfig/
-T选项指定输入文件,-X选项指定包含要排除的文件列表
创建文件并且添加要压缩的文件
[root@centos72 ~]# cat filelist.txt
/etc/issue
/etc/passwd
/etc/services
/root/anaconda-ks.cfg
如果文件名很长可以在文件里面输入:r!ls ，文件的路径就会自动补齐
:r!ls /root/anaconda-ks.cfg，按回车键就会把文件的完整路径输入到光标指定的地方
读取文件里面的文件列表，并且进行压缩
[root@centos72 ~]# tar -T filelist.txt -Jcvf /app/fl.xz
tar: Removing leading `/' from member names
/etc/issue
/etc/passwd
/etc/services
/root/anaconda-ks.cfg
[root@centos72 ~]# ls /app

-rw-r--r-- 1 root root 101048 May 3 11:21 /app/fl.xz
[root@centos72 ~]# ls /app/fl.xz -lh
-rw-r--r-- 1 root root 99K May 3 11:21 /app/fl.xz
tar: Removing leading `/' from member names表示把文件最前面的/删除了
预览的时候可看到，这样做的好处是解压的时候文件是相对路径，不会覆盖原来的文件
[root@centos72 ~]# tar tvf /app/fl.xz
-rw-r--r-- root/root 23 2018-11-23 21:16 etc/issue
-rw-r--r-- root/root 1161 2019-05-02 14:05 etc/passwd

-rw------- root/root 1592 2019-01-13 00:22 root/anaconda-ks.cfg
分割大的 tar 文件为多份小文件：
split –b Size –d tar-file-name prefix-name
split -b 1M –d mybackup.tgz mybackup-parts
split -b 1M mybackup.tgz mybackup-parts
有些网站对文件大小有限制，那么就要先把文件切割成小份再上传
对系统目录进行打包压缩，并且切分成4M一个的文件
[root@centos72 ~]# tar cf /app/etc.tar /etc/
tar: Removing leading `/' from member names
[root@centos72 ~]# ls /app/etc.tar -lh
-rw-r--r-- 1 root root 32M May 3 11:31 /app/etc.tar
