Linux Tips

linux双系统之后要执行

grub2-mkconfig -o /boot/grub2/grub.cfg
# 而且先装win是没必要的，但是这样的话需要开机按f10（或者其他）來选择系统，用f2來选择默认系统。（反正对我一般用linux的來说没关系）

Cannot change ownership to uid 1000 , gid 1000: Permission denied

tar xzf $INPUT_FOLDER/archive.tar.gz --no-same-owner -C

su 不能切换

chmod u+s,g-w,o-w /bin/su

开机调节亮度

sudo vi /etc/rc.local
: #! /usr/bin/bash
: echo 80 > /sys/class/backlight/intel_backlight/brightness
: exit 0
sudo ln -s /etc/rc.local /etc/rc.d/rc.local
sudo service rc-local start
echo $?
sudo service rc-local status

定时关机

shutdown -r now                 # 关机后重启
shutdown -h now                 # 关机后不重启
shutdown -r +10                 # 10 分钟后重启
shutdown -r 10:00               # 10 点钟重启
shutdown -h +10                 # 10分钟后关机
shutdown -h 10:00               # 10 点钟关机

#Debian, Ubuntu.
sudo ln -s /opt/lampp/lampp /etc/init.d/lampp
sudo update-rc.d lampp start 80 2 3 4 5 . stop 30 0 1 6 .

# RedHat, Fedora, CentOS. If your Linux distro uses "chkconfig" tool to install the services you can run the following commands:
sudo ln -s /opt/lampp/lampp /etc/init.d/lampp
sudo chkconfig --add lampp

yum install yum-utils
package-cleanup --oldkernels --count=1
