經(jīng)過(guò)長(zhǎng)時(shí)間學(xué)習(xí)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(yīng)用，在這里拿出來(lái)和大家分享一下，希望對(duì)大家有用。

Linux基本命令：
who查看當(dāng)前user
ps aux (我經(jīng)常多一個(gè)‘－’，有一行錯(cuò)誤信息)
netstat (具體man or info to CC)
shutdown reboot關(guān)機(jī)命令
shutdown語(yǔ)法：
／sbin/shutdown[-t秒]［－arkhncfF時(shí)間］［警告信息］
eg:
／sbin/shutdown -h 10 'Server will be shutdowned after 10 mins'

man下的參數(shù)：
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(diǎn)關(guān)機(jī)
shutdown -h ＋1010mins后關(guān)機(jī)
shutdown -r now (reboot at once)
shutdown -r +30 'System will reboot in 30mins'
shutdown -k 'System will reboot'(發(fā)送警告信息)

reboot命令
shutdown -r now幾乎與reboot相同，關(guān)機(jī)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(jī)模式root）
