# 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

[root@centos72 ~]# tar  -cvf   /app/sysconfig.tar /etc/sysconfig/ tar: Removing leading `/' from member names /etc/sysconfig/ /etc/sysconfig/ip6tables-config /etc/sysconfig/iptables-config /etc/sysconfig/cbq/ /etc/sysconfig/cbq/avpkt /etc/sysconfig/cbq/cbq-0000.example /etc/sysconfig/rdisc /etc/sysconfig/console/ /etc/sysconfig/init /etc/sysconfig/modules/ /etc/sysconfig/netconsole /etc/sysconfig/network-scripts/ /etc/sysconfig/network-scripts/ifcfg-lo /etc/sysconfig/network-scripts/ifdown /etc/sysconfig/network-scripts/ifdown-bnep /etc/sysconfig/network-scripts/ifdown-eth /etc/sysconfig/network-scripts/ifdown-ippp /etc/sysconfig/network-scripts/ifdown-ipv6 /etc/sysconfig/network-scripts/ifdown-isdn /etc/sysconfig/network-scripts/ifdown-post /etc/sysconfig/network-scripts/ifdown-ppp /etc/sysconfig/network-scripts/ifdown-routes /etc/sysconfig/network-scripts/ifdown-sit /etc/sysconfig/network-scripts/ifdown-tunnel /etc/sysconfig/network-scripts/ifup /etc/sysconfig/network-scripts/ifup-aliases /etc/sysconfig/network-scripts/ifup-bnep /etc/sysconfig/network-scripts/ifup-eth /etc/sysconfig/network-scripts/ifup-ippp /etc/sysconfig/network-scripts/ifup-ipv6 /etc/sysconfig/network-scripts/ifup-isdn /etc/sysconfig/network-scripts/ifup-plip /etc/sysconfig/network-scripts/ifup-plusb /etc/sysconfig/network-scripts/ifup-post /etc/sysconfig/network-scripts/ifup-ppp /etc/sysconfig/network-scripts/ifup-routes /etc/sysconfig/network-scripts/ifup-sit /etc/sysconfig/network-scripts/ifup-tunnel /etc/sysconfig/network-scripts/ifup-wireless /etc/sysconfig/network-scripts/init.ipv6-global /etc/sysconfig/network-scripts/network-functions /etc/sysconfig/network-scripts/network-functions-ipv6 /etc/sysconfig/network-scripts/ifdown-Team /etc/sysconfig/network-scripts/ifdown-TeamPort /etc/sysconfig/network-scripts/ifup-Team /etc/sysconfig/network-scripts/ifup-TeamPort /etc/sysconfig/network-scripts/ifcfg-ens33 /etc/sysconfig/network-scripts/ifcfg-ens37 /etc/sysconfig/readonly-root /etc/sysconfig/crond /etc/sysconfig/run-parts /etc/sysconfig/selinux /etc/sysconfig/wpa_supplicant /etc/sysconfig/ebtables-config /etc/sysconfig/grub /etc/sysconfig/irqbalance /etc/sysconfig/man-db /etc/sysconfig/rsyslog /etc/sysconfig/firewalld /etc/sysconfig/kdump /etc/sysconfig/sshd /etc/sysconfig/authconfig /etc/sysconfig/cpupower /etc/sysconfig/kernel /etc/sysconfig/network /etc/sysconfig/anaconda /etc/sysconfig/chronyd /etc/sysconfig/ntpdate /etc/sysconfig/ntpd /etc/sysconfig/keepalived /etc/sysconfig/ipvsadm-config /etc/sysconfig/nginx /etc/sysconfig/nginx-debug /etc/sysconfig/htcacheclean /etc/sysconfig/httpd

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 37988 May 3 10:22 sysconfig.tar.xz -rw-r--r-- 1 root root 47000 May 3 10:22 sysconfig.tar.gz -rw-r--r-- 1 root root 235520 May 3 10:10 sysconfig.tar ----rwx--- 1 root root 15 May 2 23:42 aa.txt -rw-r--r-- 1 root root 832545 May 2 23:37 messages -rw-r--r-- 1 root root 108052 May 2 23:28 messages.zip -rw-r--r-- 1 root root 80145 May 2 23:24 sysconfig.zip -rw-r--r-- 1 root root 831851 May 2 23:00 m1 -rw------- 1 root root 106019 May 2 22:59 m.gz.txt -rw-r--r-- 1 root root 831851 May 2 22:46 mmm -rw-r--r-- 1 root root 831851 May 2 17:58 mm -rw-r--r-- 1 root root 49513 May 2 17:58 mm.bz2 -rw-r--r-- 1 root root 197701 May 2 17:55 m.z -rw------- 1 root root 106019 May 2 17:31 m.gz

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
