linux怎么查询台账信息

1)系统安装时间

passwd -S root[(27) root@Fedora~]#passwd -S rootroot PS 2017-05-27 0 99999 7 -1 (密码已设置，使用SHA512算法)输出信息：root：代表查询的用户PS:表示已经存在密码或者已经被锁。NP 表示没有密码  LK 表示用户被锁2017-05-27 ：表示上次用户密码更改时间0    ：密码更改最小日期99999    ：密码更改最大日期7    ：密码过期提醒期限-1   ：密码过期后仍可使用的时间原文： -S     Report  password  status  on  the  named account. The first part           indicates if the user account is locked (LK),  has  no  password           (NP),  or  has  an  existing or locked password (PS). The second            part gives the date of the last password change. The next  parts            are the minimum age, maximum age, warning period, and inactivity            period for the password.

2)查询MAC

[(33) root@Fedora~]#ifconfigenp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 10.20.41.182  netmask 255.255.0.0  broadcast 10.20.255.255        inet6 fe80::223:9eff:fe03:da00  prefixlen 64  scopeid 0x20<link>        ether 00:23:9e:03:da:00  txqueuelen 1000  (Ethernet)        RX packets 1148342  bytes 300679175 (286.7 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 877017  bytes 302273584 (288.2 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0        device interrupt 3  其中ether就是MAC地址查询mac地址第二种方法：lshw -c network[(32) root@Fedora~]#lshw -c network  *-network                      description: Ethernet interface       product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller       vendor: Realtek Semiconductor Co., Ltd.       physical id: 0       bus info: pci@0000:02:00.0       logical name: enp2s0       version: 0c       serial: 00:23:9e:03:da:00       size: 100Mbit/s       capacity: 1Gbit/s       width: 64 bits       clock: 33MHz       capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation       configuration: autonegotiation=on broadcast=yes driver=r8168 driverversion=8.042.00 duplex=full ip=10.20.41.182 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s       resources: irq:3 ioport:5000(size=257) memory:58100000-58101000 memory:58200000-58204000其中serial就是MAC地址

3)查询硬盘序列号：
