⑩②. 打包或解压tar 重点
- ①. 打包为 tar 格式的文件:
[root@localhost home]# tar -cvf hello.tar hello hello-hard hello-soft hello hello-hard hello-soft [root@localhost home]# ls hello hello-hard hello-soft hello.tar test test-soft [root@localhost home]#
②. 压缩为 tar.gz 格式的文件:
[root@localhost home]# tar -zcvf test.tar.gz test test-soft test/ test-soft [root@localhost home]# ls hello hello-hard hello-soft hello.tar test test-soft test.tar.gz [root@localhost home]#
③. 解打包 tar 格式的文件:
[root@localhost home]# tar -xvf hello.tar hello hello-hard hello-soft [root@localhost home]# ls hello hello-hard hello-soft hello.tar test.tar.gz [root@localhost home]#
④. 解压缩 tar.gz 格式的文件:
[root@localhost home]# tar -zxvf test.tar.gz test/ test-soft [root@localhost home]# ls hello hello-hard hello-soft hello.tar test test-soft test.tar.gz [root@localhost home]#
⑩③. 软链接 (快捷方式)
- ①. 也成为符号链接,类似于windows里的快捷方式,有自己的数据块,主要存放了链接其他文件的路径
- ②. 命令 ln –s 原文件或目录名 软链接名
- ③. 查询:通过 ls -l 就可以查看,列表属性第1位是l,尾部会有位置指向
