linux sha256sum 检查已安装rpm包

sha256sum 对比sha-256散列值

• 为了方便查看目录结构，安装了tree软件包，现在检查一下它。

# rpm -qa | grep tree
tree-1.7.0-18.oe1.aarch64

# rpm -ql tree-1.7.0-18.oe1.aarch64 --dump

• 要比较的是这一条

/usr/bin/tree 134664 1584991303 7ed43d5d984321e3ea4ca7bc471f2210630d0a976bea7baede2c98c35e00b7e4 0100755 root root 0 0 0 X

对比所属的用户和用户组

# cd /usr/bin/
