講解Linux基礎命令之：man、reboot
經過長時間學習Linux基本命令，man與reboot命令還是比較常用的，于是我研究了一下man與reboot應用，在這里拿出來和大家分享一下，希望對大家有用。
Linux基本命令：
who查看當前user
ps aux (我經常多一個‘－’，有一行錯誤信息)
netstat (具體man or info to CC)
shutdown reboot關機命令
shutdown語法：
／sbin/shutdown[-t秒]［－arkhncfF時間］［警告信息］
eg:
／sbin/shutdown -h 10 'Server will be shutdowned after 10 mins'
man下的參數：
OPTIONS
◆-r Requests that the system be rebooted after it has been brought down.
◆-h Requeststhatthesystembe either halted or powered off after it has been brought down, with the choice as to which left up to the system.
◆-H Requests that the system be halted after it has been brought down.
◆-P Requests that the system be powered off after it has been brought down.
◆-c Cancels a running shutdown.TIME is not specified with this option,the first argument is MESSAGE.
◆-k Onlysendoutthe warning messages and disable logins, do not actually bring the system down.
eg:
shutdown -h now/0
shutdown -h 10:00 /*10點關機
shutdown -h ＋1010mins后關機
shutdown -r now (reboot at once)
shutdown -r +30 'System will reboot in 30mins'
shutdown -k 'System will reboot'(發送警告信息)
reboot命令
shutdown -r now幾乎與reboot相同，關機之前輸入回填指令：
sync;sync;sync;reboot
fsck - check and repair a Linux file system
fsck /dev/hda7:
To clear the wrong disk block of /dev/hda7 （單人單機模式root）
